Abstract:
A channel layer is formed of an oxide semiconductor. A first insulating film is provided on the channel layer, a source line, and a drain electrode, and includes a drain contact hole which reaches the drain electrode. A pixel electrode is provided on the first insulating film, includes a connection conductive layer which is connected to the drain electrode by the drain contact hole, and is formed of a transparent conductive material. The pixel electrode is covered with a second insulating film. A common electrode is provided on the second insulating film, includes an opening which faces the pixel electrode in a thickness direction, and is formed of a transparent conductive material. A metal layer, in conjunction with a part of the common electrode, forms a laminated structure, and includes a light-shield part which overlaps the channel layer at least partially in plan view.
