Abstract:
1. A method for forming a liquid crystal display having a plurality of scan lines and a plurality of video data lines crossing each other to define a plurality of pixel regions on a substrate, the method comprising: forming a plurality of pixel electrodes in the pixel regions, wherein two adjacent scan lines and two adjacent video data lines define a pixel region, and each pixel region includes a pixel electrode, each pixel electrode is formed by a first sub-pixel electrode and a second sub-pixel electrode, wherein the second sub-pixel electrode is adjacent and directly connected to the first sub-pixel electrode without through other element to form the pixel electrode; forming a plurality of switching devices in the pixel regions respectively, wherein each of the switching devices comprises a first switching transistor and a second switching transistor and has at least one gate electrode connected to a corresponding scan line, at least one source electrode connected to a corresponding pixel electrode and at least one drain electrode connected to a corresponding video data line; and forming a plurality of storage capacitors in the pixel regions respectively, each of the pixel regions includes at least a first storage capacitor and a second storage capacitor coupling to video data lines through corresponding switching device, and the first storage capacitor corresponds to said first sub-pixel electrode and the second storage capacitor corresponds to said second sub-pixel electrode, wherein, in at least one of the pixel regions, the first storage capacitor and the second storage capacitor are formed by different process rounds to have different process parameters respectively.
