DISPLAY DEVICE, DISPLAY MODULE, AND ELECTRONIC APPARATUS

WIPO Patent Application WO/2019/135147

A1

Provided is a liquid crystal display device that has a high aperture ratio. A display device in which pixels have a transistor, a first insulation layer, a second insulation layer, a third insulation layer, a first conduction layer, a pixel electrode, a common electrode, and a liquid crystal layer. The first insulation layer is positioned on a channel formation region of the transistor. The first conduction layer is positioned on the first insulation layer. The second insulation layer is positioned on the transistor, the first insulation layer, and the first conduction layer. The pixel electrode is positioned on the second insulation layer, the third insulation layer is positioned on the pixel electrode, the common electrode is positioned on the third insulation layer, and the liquid crystal layer is positioned on the common electrode. The common electrode has a region that overlaps the first conduction layer with the pixel electrode therebetween. The pixels have: a first connection part at which the pixel electrode is electrically connected to the transistor; and a second connection part at which the first conduction layer is electrically connected to the common electrode. The first conduction layer, the pixel electrode, and the common electrode can each transmit visible light.
