Abstract
A first metal layer, an inorganic insulating film, and a second metal layer are provided. A first wiring line led to a peripheral edge of a cutout portion is provided in the first metal layer. A second wiring line led to the peripheral edge of the cutout portion is provided in the second metal layer. The first lead wiring line and the second lead wiring line overlap each other through intermediation of the inorganic insulating film.
Claims20
A display device comprising:
- a display region in which a cutout portion is formed;
- and
- a frame region,
- wherein the display region includes
- a plurality of data signal lines configured to transmit a data signal,
- a plurality of scanning signal lines intersecting the plurality of data signal lines,
- a plurality of light emission control signal lines, and
- a plurality of subpixel circuits being provided correspondingly to intersection points of the plurality of data signal lines and the plurality of scanning signal lines,
- the display device is provided with
- a drive circuit being electrically coupled to the plurality of data signal lines,
- a drive circuit being electrically coupled to the plurality of scanning signal lines, and
- a drive circuit being electrically coupled to the plurality of light emission control signal lines,
- the frame region in a periphery of the cutout portion includes
- a first lead wiring line being electrically coupled to a first signal line as one of the plurality of data signal lines, or one of the plurality of scanning signal lines, or one of the plurality of light emission control signal lines, and extending from the display region to the cutout portion, and
- a second lead wiring line being electrically coupled to a second signal line as another one of the plurality of data signal lines, or another one of the plurality of scanning signal lines, or another one of the plurality of light emission control signal lines, and extending from the display region to the cutout portion, the second signal line being adjacent to the first signal line,
- the first lead wiring line is provided in a first metal layer,
- the second lead wiring line is provided in a second metal layer being different from the first metal layer, and
- the first lead wiring line and the second lead wiring line are superposed on each other through intermediation of an inorganic insulating film,
- wherein, in the display region, the first signal line and the second signal line are formed adjacent to each other in the first metal layer.
