Abstract
Single cell gap transflective liquid crystal display mode with vertically aligned negative liquid crystal was developed. Reflectance curve as a function of voltage matched exactly with transmittance curve. Threshold voltage in reflectance curve was around 2.0V, as in transmittance curve, and the voltage for maximum reflectance was around 4.5V∼5.0V, which gave also the maximum transmittance. Reflective region was divided into two parts. First reflective part was driven by the voltage supplied by switching transistor directly, while the second reflective part was driven by the voltage lower than that of first part using the voltage-dividing capacitor connected to switching transistor in series. Normal 8 mask-count process was applied to fabrication of real panels. No special optical film or extra driving circuit was required.
