Abstract: An inventive array substrate for the transflective liquid crystal display device includes a pixel electrode, a reflective electrode, and an interposed insulation layer. When the pixel electrode is under the reflective electrode, the sum of the thickness of the insulation layer and the reflective electrode is less than 0.5 micrometers. In other embodiments, upper surfaces of the reflective and pixel electrodes are on the same plane. This results from adjusting the thickness and changing the structure such as adopting a drain supplementary electrode extended from the drain electrode of the thin film transistor or positioning the pixel electrode within the transmitting hole of the reflective electrode.

Abstract: A transflective liquid crystal display device includes a liquid crystal panel, which can be used in the transparent mode and reflective mode, selectively. The transflective liquid crystal panel includes the pixel electrode having the transparent electrode and reflective electrode and the reflective film having the transmitting hole. Therefore, the light generated from the backlight device can pass through the transmitting hole and transparent electrode into the liquid crystal. Moreover, the light reflected in the reflective film can also pass through them into the liquid crystal without being absorbed by the lower polarizer. That is, the brightness of the transflective LCD device is improved.
