Due to the worldwide adoption to digital television, many home appliance vendors are investing in liquid-crystal-display television (LCD TV). With the phenomenal potential for the LCD TV market, non-traditional TV vendors are also stepping in. Although there are various ways to view digital content such as set-top box, digital download and others, most consumers choose to buy LCD TV because of its price, price-on-performance and others. This thesis is to prove why people (buyers and sellers) prefer LCD TV over other technologies and how the global market is reacting to this adoption. By using brainstorming and Porter’s five force analysis, different aspects were considered such as current TV market by vendors and regions, other TV technologies, market drivers, competitive rivals and threats of suppliers, buyers, substitutes and potential entrances. After viewing those perspectives, LCD TV is the right technology at the right time. Keywords: liquid-crystal display television, LCD TV, TV technology, digital TV

液晶面板是跨世紀的新發明，這個產業更是百年產業，隨著技術的演進與產業的更替，這個產業最重要且關鍵殺手級的應用－平面電視機，終於在近些年逐漸引爆且蓬勃發展。本研究應用經濟學寡佔模型中的部分理論，分別就大尺寸電視液晶面板產業的競爭與合作關係依價格與產能兩大關鍵因素進行探討，並運用相關賽局理論探討各競爭廠商的策略思維，以期能對未來產業的競爭或相關類似產業架構的產業提供些許建議。 / The industry of TFT-LCD draws much attention for decades because of the world class business opportunities. The most important killer application, FPD（Flat-Panel Display）,starts booming these recent years. This study tries to apply some economy theories such as Oligopoly, Cournot Model and Bertrand Model to analyze the competition between prices and quantities. And we also analyzed the interaction of competition from the view of Game Theory and so on.

近年來，由於液晶顯示器市場中的企業，目前正進入「最適經營模式」之關鍵時刻，也就是企業均處於一個最佳的營運模式，據以維持或提高企業在市場上的競爭力。然而，國內在此產業中之相關企業大多數係以降低成本為提昇競爭力的主要策略之一，但如此經營策略並非完全適合國內企業的經營模式。因此，為能進一步瞭解C公司經營績效的良窳，且探究經營績效之影響因素。 　　有鑑於此，本研究擬針對C公司之銷售數量與額度的影響因素，進行探究，藉以瞭解該公司之銷售地區、產品等級、產品種類等因素的影響關係。其研究結果顯示： 1. 地區對產品等級與產品種類的選擇有顯著影響； 2. 台灣地區的銷售額度顯著較其他地區為高； 3. A產品銷售額度顯著較其他種類產品為高； 4. 平均每月銷售額度會受前一期的影響。

Taiwan and Korean are in fierce competition in the LCD panel industry and together dominate over 70% of the international market share. Business strategies in Taiwan rely on Original Equipment Manufacturers (OEMs) whereas Korea focuses principally on vertical integration, including development of its own international brand architecture. Taiwan is one of the world’s largest providers of LCD panel. In 1998, Taiwan accounted for only 1% of market share worldwide, but by 2002 its market share was over 30%. This study examines the causes behind Taiwanese LCD makers, CMI, AUO, growth and analysis their competitors (Korean makers). TFT-LCD manufactures’ strategies and activities help to develop a greater understanding. With respects to the Taiwanese LCD industry, many previous studies have concluded that the Taiwanese government played a major role in the initial stages of development. - Government support, Tax incentive - LCD manufacturer’s activities on marketing and cost effectiveness With regard to recent business movement between LCD manufacturers, strategic alliance is to be a popular way to enhance their competitiveness. But common alliance among same business fields is not good enough to be a market leader. Based on supply chain analysis and case study, intimate cooperation with other business field is proved as more powerful competitive strategic alliance. This new alliance will lead more efficient development lead time and productivity.

在節能、無輻射、高解析度、更具時尚的設計等優勢下，全球液晶電視取代傳統CRT電視的趨勢已經愈來愈明顯，各液晶電視品牌電視大廠對於委外生產的比例亦逐年提高。因此吸引了台灣許多廠商爭相跨足液晶電視代工的行列。 在發展液晶電視代工的廠商中，本研究針對廠商的特性將發展液晶電視的代工廠商歸類傳統家電廠、面板廠、筆記型電腦代工廠、監視器專業製造廠商四大類。本研究以邱志聖教授的策略行銷4C架構來分析這四類製造廠商的發展演進，並對這四類製造廠商未來發展提出看法，以做為液晶電視代工業者未來擬定策略的參考方向。 / With the advantages of less energy consumption and radiation, higher resolution, good looking in design, the trend that LCD TV replaces traditional CRT TV is very obvious. In the mean time, the outsourcing percentage for brand name customer is also getting higher and higher. Therefore, many manufacturing companies in Taiwan are aggressive to put their resources in this competition in order to get more outsourcing LCD TV order. The companies involving the LCD TV OEM/ODM can be divided by Home Appliance companies、panel makers、notebook OEM manufacturers and monitor OEM manufacturers. In this research, systematic analysis is done based on “Strategic Marketing Analysis” for the four kinds of companies. Hope it can provide some good information and reference to those companies when developing their LCD TV OEM/ODM strategy in the future.

水晶体のようにレンズを動かすことなく，その焦点距離の制御を行うため、本論文では複屈折性をもつ液晶材料を利用した小型かつ薄型で耐環境性の高い可変焦点レンズ（液晶レンズ）の開発を目指している．特に、従来のように液晶の分子配向制御に電界を用いず、超音波振動により分子配向を静的に制御する手法とそのメカニズムの解明を目的とする。 / Variable-focus ultrasound liqui dcrystal lenses combining ultrasonic waves and liquid crystal materials were developed and investigated, focusing on the multifunctional properties that were not possible with conventional optical lenses. In particular, control of the effective lens aperture, control of the focal point in the radial direction for image stabilizationt, and expansion of the focal length variation range, which had been considered a problem from a practical standpoint, were investigated. / 博士(工学) / Doctor of Philosophy in Engineering / 同志社大学 / Doshisha University

液晶顯示器(LCD)產業是二十一世紀最令人矚目的產業，不僅因為液晶顯示器是一項融合了高科技與大量經濟投資的產業，更因為液晶顯示器的各種應用與消費者的日常生活習習相關，因此具有無限潛力的特色。 近年來，液晶顯示器隨著面板價格的快速滑落，使得液晶顯示器的售價越來越能讓消費者接受，也吸引了眾多的廠商投入，包含原日、韓及其他國家顯示器及電視大廠，歐美之資訊品牌或通路，台灣廠商也積極切入液晶顯示器和電視廠商之OEM及ODM代工，少數台商也切入自有品牌，也由於液晶顯示器價格的大幅滑落，新技術的興起，及眾多廠商的競逐其中，造成當前液晶顯示器產業之異常激烈競爭環境，而LCD 產業為台灣兩兆雙星產業之一，故其競爭力之提升不僅攸關該產業各相關企業存亡，對台灣維繫其日益流失之競爭優勢亦具樞紐地位，所以如何加強競爭力，並結合政府及民間之力量，從容面對日本、韓國之威脅，是國內目前產官學界所必須共同努力之目標。 經研究結果發現，個案公司之主要競爭優勢在於掌握關鍵零組件之生產、彈性之製造管理能力及全球通路行銷，積極進行策略聯盟以尋求與供應商上中下游及行銷通路間的垂直整合，以強化企業之競爭優勢。因此業者必須掌握企業核心競爭力、認清液晶循環趨勢及擬定企業競爭策略;進而尋求企業合併，並且建議政府提供穩定的投資環境與提昇廠商研發能力，藉以在液晶顯示器產業中取得持續性的競爭優勢。 本研究運用包含「五力分析」、「鑽石模型」、「競爭策略」及「SWOT」等產業分析理論，來研究企業如何建立核心能力，進一步歸納出液晶顯示器廠商競爭優勢的經營策略，並從中萃取出產業關鍵成功因素，以期望能提供作為業界參考及學習之用，並作為公司擬定其未來策略方針之用。
