Abstract
According to one embodiment an array substrate includes a semiconductor layer scanning and signal lines first and second insulating layers a pedestal and a pixel electrode. The scanning line is opposed to the semiconductor layer. The first insulating layer is provided above the semiconductor layer. The signal line and the pedestal are connected to the semiconductor layer through first and second contact holes in the first insulating layer. The second insulating layer is provided above the pedestal. The pixel electrode is connected to the pedestal through a third contact hole in the second insulating layer. The signal line and the pedestal are provided in layers different from each other.
Claims5
A display device comprising:
- a semiconductor;
- a scanning line opposed to the semiconductor;
- a signal line connected to the semiconductor;
- a wiring connection layer which is in contact with both of the signal line and the semiconductor;
- a pedestal electrode which is in contact with the semiconductor and is formed in a same layer as that of the wiring connection layer;
- a first insulating layer covering the wiring connection layer and the pedestal electrode;
- and
- a pixel electrode connected to the pedestal electrode through a first contact hole formed in the first insulating layer
- wherein
- a thickness of the pedestal electrode is smaller than a thickness of the signal line,
- the signal line is connected to the wiring connection layer through a second contact hole formed in the first insulating layer, and
- an area of the wiring connection layer is smaller than an area of the pedestal electrode.
