Abstract:
1. A liquid crystal display device, comprising: a first substrate; a second substrate opposing to the first substrate; columnar spacers provided on the second substrate for keeping a specific gap with respect to the first substrate; a liquid crystal material filled in the gap; a first metal layer provided partially on the first substrate; an insulating film provided on the first substrate and on the first metal layer; a semiconductor layer provided partially on the insulating film; a second metal layer provided on the insulating film and on the semiconductor layer; a first wiring formed with the first metal layer; a second wiring formed with the second metal layer; sub-pixels formed in each of a plurality of regions sectioned by the second wirings neighboring to each other and the first wirings neighboring to each other, wherein plural of said sub-pixels define a pixel; and storage capacitors formed with the first metal layer, the insulating film, and the second metal layer, wherein each of the sub-pixels of the liquid crystal display device further comprise a step film formed with the semiconductor layer, each of the step films having a same area in all the sub-pixels in a forming part of the storage capacitor, the plurality of sub-pixels includes a sub-pixel in which the step film is provided at a position where the columnar spacer abuts, and a sub-pixel in which the step film is provided at a position away from the columnar spacer, and the columnar spacers are formed at same positions in the sub-pixels in which the columnar spacers are provided.
