Abstract

Each pixel region of an active matrix substrate includes a thin-film transistor, an interlayer insulating layer that includes an organic insulating layer, a transparent connection layer formed on the interlayer insulating layer, an inorganic insulating layer formed on the transparent connection layer, and a pixel electrode formed on the inorganic insulating layer. The transparent connection layer contacts a drain electrode inside of a first contact hole formed in the interlayer insulating layer. The pixel electrode contacts the transparent connection layer inside of a second contact hole formed in the inorganic insulating layer. The first contact hole and the second contact hole do not overlap with one another when a substrate is viewed from a normal direction. Inside the first contact hole, a bottom surface and sidewalls of the first contact hole are covered by the transparent connection layer, the inorganic insulating layer, and the pixel electrode.
