Pixel structure and fabricating method thereof

摘要

The pixel structure includes a scan line, a data line, a thin-film transistor, a first electrode layer, a protective layer and a second electrode layer. The thin-film transistor is electrically connected to the scan line and the data line, and includes a gate, an oxide semiconductor layer, an insulating layer, a source and a drain. The first electrode layer is in the same layer as the oxide semiconductor layer, and is surrounded by the scan line and the data line. The second electrode layer is located on the first electrode layer, and the protective layer is located between the first electrode layer and the second electrode layer, wherein one of the first and second electrode layers is electrically connected to the thin-film transistor, and the other is connected to a common voltage. The second electrode layer includes a plurality of slits exposing an area of the first electrode layer.
