Abstract: A performance of a display apparatus is improved. A display apparatus has a display region, a transparent region and a frame region. The display apparatus includes a plurality of scan signal lines extending in an X direction in the display region and a plurality of image signal lines extending in a Y direction in the display region. The plurality of image signal lines include a first wiring (image signal line) and a second wiring (image signal line). The first wiring includes a first bypass wiring portion arranged in the frame region and a first extension wiring portion connected to an end of the first bypass wiring portion and extending in the Y direction. The second wiring includes a second bypass wiring portion arranged in the frame region and a second extension wiring portion connected to an end of the second bypass wiring portion and extending in the Y direction. In a plan view, the first wiring and the second wiring intersect with each other at the frame region.
