Abstract
A pixel structure having the following structure is provided. A light-shielding layer with a flat layer covering thereon is disposed on a substrate. A channel layer, a data line and a first pad are disposed on the flat layer. A source and a drain partially cover two sides of the channel layer. A gate dielectric layer with a gate, a scan line and a second pad disposed thereon covering the channel layer, the source and the data line exposes the drain and the first pad. A protection layer covering the gate and the scan line exposes the drain, the first and second pads. A patterned transparent conductive layer includes a pixel electrode disposed on the protection layer, a first retain portion disposed on the first pad and a second retain portion disposed on the second pad.
Claims12
A pixel structure, comprising:
- a light-shielding layer, disposed on a substrate;
- a flat layer, covering the light-shielding layer;
- a channel layer, disposed on the flat layer and located above the light-shielding layer;
- a source and a drain, partially covering two sides of the channel layer and electrically connected to the channel layer, respectively;
- a data line and a first pad, disposed on the flat layer, wherein the data line is connected between the source and the first pad;
- a gate dielectric layer, covering the channel layer, the source and the data line, and exposing the drain and the first pad;
- a gate, disposed on the gate dielectric layer and located above the channel layer;
- a scan line and a second pad, disposed on the gate dielectric layer, wherein the scan line is connected between the gate and the second pad;
- a protection layer, covering the gate and the scan line, and exposing the drain, the first pad and the second pad;
- and
- a patterned transparent conductive layer, including a pixel electrode, a first retain portion and a second retain portion, wherein the pixel electrode is disposed on the protection layer and electrically connected to the drain, and the first and second retain portions are located on the first pad and the second pad, respectively.
