1997 marked the 10th year since the mass production of TFT- LCD was started. During the intervening years, as TFT-LCD advanced rapidly to become an industry of its own, its market size reached about 4 billion dollars in 1996. In addition, there are opportunities for future growth, and the market is expected to grow to 15 billion dollars by the year 2000. New applications for TFT-LCDs are emerging such as car navigation, personal data assistants and monitor displays. In this paper, through looking back on these 10 years of progress, the technical requirements for future expansion of TFT-LCDs are discussed. The trends of manufacturing, the relationship between the process technology and equipment, and a representative key technical term are shown as its market size expands. Four periods are defined such as 'The Beginning, 1987-90', 'The expansion, 1991-94', 'The Fall, 1995' and 'Today and the near future 1996-99'.
