Abstract:
1. A thin film transistor substrate, comprising: a substrate; a thin film transistor provided on the substrate; a first insulating layer provided over the thin film transistor; a lower layer transparent electrode provided over the first insulating layer; a second insulating layer covering the lower layer transparent electrode; and a pixel electrode provided on the second insulating layer, wherein the lower layer transparent electrode, the second insulating layer, and the pixel electrode form an auxiliary capacitance, wherein the thin film transistor and the pixel electrode are electrically connected to each other in a contact hole penetrating the first insulating layer and the second insulating layer through a connecting transparent electrode disposed in the contact hole, the connecting transparent electrode being separate from the lower layer transparent electrode, wherein the thin film transistor includes a semiconductor layer consisting a channel, and the semiconductor layer and the contact hole are disposed so as to overlap in a direction normal to the substrate, and wherein the semiconductor layer and the connecting transparent electrode are in direct contact with each other.
