Currently the major TFT-LCD manufacturers cluster in South Korea, Taiwan and Japan, which totally contribute more than 80% sales in global market. These TFT-LCD manufacturers all face the five industry characteristics, including the intensive capital, the intensive technology, the short product life cycle and high technology renewal speed of production lines, the fluctuating prices easily influenced by market demand/supply condition and business cycle, and the international division of labor. Nowadays, TFT-LCD monitor has become the mainstream of display panel products in ICT (Information and Communications Technology) industry. Japan, Taiwan and South Korea are focusing on the developing of the panel display industry, and China is also ambitious and its intelligence can't be neglected in the future. In view of the rapid growth of global demand, TFT-LCD manufacturers face a tremendous competition environment. Therefore, how to configure the best resource allocation and create more profits tend to be a major issue for the managers of the TFT-LCD industry. The empirical research results of this study found that South Korean firms had relatively better stable operation performances; the performances of the firms in Taiwan and Japan were relatively worse and varied over time. After referring to the disclosure statements and industrial experts' opinions, this paper also found that the reason of Sony Corporation with great performance in 2007 was the hot sales of high-level touch panels which lead to the high gross profit ratio of 50% and rapidly increasing pretax profit in 2007. As a result, how to develop high-level or multi-function panels is a significant issue for the TFT-LCD manufacturers in Taiwan
