  • Publication number: 20100033660
    Abstract: An array substrate includes scanning lines, signal lines, switching elements, an insulating film, a reception pattern which has a first frame, and a second frame, in which a groove is formed between the first frame and second frame, a projection which is formed in a part of the groove adjacent to the first frame, extended in a first coating direction, and controls the flow of light-shielding material, and a frame-like light-shielding pattern, which includes a first light-shielding part formed by coating the groove with the light-shielding material in the first coating direction by using an ink-jet method or a dispenser method, and is formed by coating the groove several times with the light-shielding material by using an ink-jet method or a dispenser method.

  • Publication number: 20080055524
    Abstract: Provided is a liquid crystal display device that makes it possible to prevent coating unevenness of a colored layer from occurring. The liquid crystal display device includes a first colored layer, a second colored layer and a third colored layer, which layers are formed in a display area. In the liquid crystal display device, the first colored layer is arranged in a grid pattern in a manner of surrounding the second colored layer and the third colored layer. In addition, when (n, m) denotes the coordinates of a pixel having a grid square formed therein in the display area, grid squares are omitted in at least pixels of (n?1, m?1), (n?1, m+1), (n+1, m?1) and (n+1, m+1).
