Abstract
A pixel electrode is formed from a transparent conducting film. A gate insulating layer includes a region including a portion of a thin-film transistor that makes contact with a semiconductor layer and a thinned region. The pixel electrode is disposed over a part of the thinned region. A dielectric layer is in direct contact with another part of the thinned region. An upper surface of the gate insulating layer has a stepped portion. The stepped portion includes a stepped portion that extends flush with a side surface of a lower layer of a drain electrode. The pixel electrode extends over at least a part of the stepped portion and at least a part of the side surface of the lower layer of the drain electrode from above the thinned region and is connected to an upper layer of the drain electrode.
