Abstract: A display panel includes a common electrode formed in an upper layer above a data line, a first insulating layer covering the common electrode, a touch sensor line formed in an upper layer of the first insulating layer and in a first opening provided in the first insulating layer, and connected to the common electrode via the first opening, a second insulating layer covering the touch sensor line, and a pixel electrode formed in an upper layer of the second insulating layer. The first insulating layer is formed with a second opening between the common electrode and the pixel electrode. The second insulating layer is disposed in an interior of the second opening and formed with a recessed portion recessed downward into a portion above the second opening. At least a portion of the pixel electrode is disposed in the recessed portion of the second insulating layer.

Abstract: An active matrix substrate includes pixel regions each including a pixel electrode and an oxide semiconductor TFT including an oxide semiconductor layer. Each pixel electrode is electrically connected to one of adjacent two of source bus lines. The oxide semiconductor layer in the oxide semiconductor TFT of each pixel region overlaps the pixel electrode of a first adjacent pixel region. The pixel electrode of the each pixel region partially overlaps the oxide semiconductor layer in a second adjacent pixel region. The source bus lines include first and second source bus lines adjacent to each other. Pixels sets each including two pixel regions whose pixel electrodes are connected to the first source bus line and pixel sets each including two pixel regions whose pixel electrodes are connected to the second source bus line are arranged alternately between the first and second source bus lines.
