Claim Text:
1. A semiconductor device comprising: a transistor over a substrate, the transistor including a gate electrode, a first conductive layer, a second conductive layer, and an oxide semiconductor layer, wherein the gate electrode overlaps with the oxide semiconductor layer; a third conductive layer over the substrate; a first insulating layer over the oxide semiconductor layer, the first conductive layer, the second conductive layer, and the third conductive layer; a second insulating layer over the first insulating layer, the second insulating layer including an opening; a pixel electrode over the first insulating layer and the second insulating layer, the pixel electrode electrically connected to one of the first conductive layer and the second conductive layer; and a color filter between the first insulating layer and the pixel electrode, wherein the pixel electrode includes a first region and a second region, wherein the first region is overlapping with the opening, wherein the pixel electrode is in contact with a top surface of the first insulating layer in the first region, and wherein the pixel electrode is in contact with a top surface of the second insulating layer in the second region, wherein the pixel electrode in the first region overlaps with the third conductive layer with the first insulating layer interposed between the pixel electrode and the third conductive layer.
