Abstract:
1. A pixel structure of a transflective liquid crystal panel having a single gap, comprising: a first substrate and a second substrate substantially corresponding to the first substrate, wherein the first substrate comprises a plurality of pixel regions, each pixel region comprising at least one reflection region covered with a reflective electrode and at least one transmission region; a liquid crystal layer disposed between the first substrate and the second substrate; a first quarter-wave plate disposed on a lower surface of the first substrate; a first polarizer, disposed under the first quarter-wave plate, having a first transmissive axis; a second quarter-wave plate disposed on an upper surface of the second substrate; and a second polarizer, disposed on the second quarter-wave plate, having a second transmissive axis, wherein the first transmissive axis of the first polarizer and the second transmissive axis of the second polarizer are substantially parallel to each other; wherein as no voltage is applied, the liquid crystal layer in the transmission region and in the reflection region has a phase difference of half wavelength, and wherein as a voltage is applied, the liquid crystal layer in the transmission region has no phase difference, and the liquid crystal layer in the reflection region has a phase difference of quarter wavelength.
