Abstract
Areflective color LCD of high quality, low power consumption, light weight and thin structure is an important device for highly portable information terminals. In this report, we numerically analyzed the relationship between the electro-optical properties and the driving voltage in a single-polarizer reflective DTN-LCD with a quarter-wave plate. We found that the LCD exhibits an achromatic image of high luminous reflectance and high contrast ratio, even if the on-voltage of TFT-LCD is reduced to 2V, the power consumption can thus be decreased to about 1/6 to 1/7 of that of a current reflective TFT-LCD of 5V at on-state.
