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.
