Abstract: A display portion is divided by scan lines and signal lines into sections where pixels are provided. Contact holes each for connecting common wiring and a common electrode together are not formed for all the pixels, but decimated so as to be arranged in zigzags.

Abstract: An active matrix substrate of a channel protection type having a gate electrode, a drain electrode and a pixel electrode isolated from one another from layer to layer by insulating films. The active matrix substrate is to be prepared by four masks. A gate electrode layer, a gate insulating film and an a-Si layer are processed to the same shape on a transparent insulating substrate to form a gate electrode layer (102 of FIG. 6) and a TFF area. A drain electrode layer (106 of FIG. 6) is formed by a first passivation film (105 of FIG. 6) via a first passivation film (105 of FIG. 6) formed as an upper layer. In a second passivation film (107 of FIG. 6) formed above it are bored an opening through the first and second passivation films and an opening through the second passivation film. A wiring connection layer is formed by ITO (108 of FIG. 6) provided as an uppermost layer. A storage capacitance unit, comprised of the first and second passivation films sandwiched between the gate electrode and an electrode layer formed as a co-layer with respect to the gate electrode, is provided in the pixel electrode.

Abstract: The method of fabricating a liquid crystal display device includes the steps of (a) fabricating a switching device on a substrate, (b) forming an interlayer insulating film on the substrate such that the switching device is covered with the interlayer insulating film, and (c) forming a transparent electrode on the interlayer insulating film, the transparent electrode being electrically connected to the switching device through the interlayer insulating film, the step (c) including (c1) depositing electrically conductive, transparent and amorphous material on the interlayer insulating film, (c2) patterning the material into the transparent electrode, and (c3) turning the transparent electrode into polysilicon by thermal annealing carried out after formation of an alignment film.
