Abstract(in English) In this study, the characteristics of a TFT driven OCB-mode LCD, which has been successfully made in our lab, will be reported. The electro-optical properties as well as the response time as a function of temperature were investigated in a detail manner. It is found that the response time between gray scale switching is still less than 600 ms even at the temperature -3℃. The initial switching time is dependent on the initial switching voltage and it can be reduced to 139 seconds as the initial switching voltage is up to 10 volts at -30℃. But the power-off switching time is independent of the voltage. We also illustrate the dependency of viewing angle properties, including the iso-contrast and the gray scale inversion, on temperature. From the experimental data, we conclude that within 0℃ to 40 ℃, the viewing angle can extend to 40 degrees.
