  • Patent number: 9733529
    Abstract: In an array substrate, a first pixel is arranged at one end of an active area, and a second pixel is arranged adjacent to the first pixel more inside of the active area than the first pixel. A common electrode extends to the first and second pixels, and an insulating layer is formed on the common electrode. First and second pixel electrodes are formed on the insulating layer in the first and second pixels. The pixel electrodes include electrode portions forming slits facing the common electrode. A second substrate includes a shield layer arranged outside the active area. The first pixel electrode is formed more widely than the second pixel electrode, and extends to outside of the active area. The first pixel electrode includes an extending portion extending to outside of the active area and facing the shield layer.

  • Patent number: 7102725
    Abstract: A substrate includes a valid area and a invalid area located outside the valid area, the valid area providing an array substrate, and a colored layers is formed in the valid area and the invalid area. A conductive film is formed on the colored layers in the valid area for forming a plurality of pixel electrodes, and the conductive film is simultaneously is formed on the colored layer in the invalid area. The substrate with the conductive film formed thereon is divided along the periphery of the valid area, thereby cutting the array substrate.
