Abstract

A display panel includes: a plurality of first wirings extending in a row direction; a plurality of second wirings extending in a column direction; and a plurality of pixels each arranged in proximity to an intersection of each of the first wirings and each of the second wirings. Two wirings of the plurality of first wirings or two wirings of the plurality of second wirings are disposed in a common region interposed between two pixels next to each other, and layouts of the respective two wirings in a thickness direction are different from each other at least in a part of each of the layouts.

wherein two wirings of the plurality of first wirings or two wirings of the plurality of second wirings are disposed in a common region interposed between two pixels next to each other, and layouts of the respective two wirings in a thickness direction are different from each other at least in a part of each of the layouts, the thickness direction being orthogonal to the row and column directions, and

wherein the two wirings of the plurality of first wirings or the two wirings of the plurality of second wirings are disposed in respective layers different from each other, in a display region of the display panel.

2. The display panel according to claim 1 , wherein each of the two wirings is a signal line to which a signal according to an image signal is applied.

3. The display panel according to claim 1 , wherein interconnection lengths of the respective two wirings are equal to each other.

4. The display panel according to claim 1 , wherein in the two pixels between which the two wirings are interposed, a layout of one of the two pixels is a reverse of a layout of the other pixel.

5. The display panel of claim 1 ,

wherein the two wirings that are disposed in the common region are separated from each other by a minimum distance D 2 , where D 2 is greater than a width of one of the two wirings that are disposed in the common region.

6. The display panel of claim 1 ,

wherein the two wirings that are disposed in the common region include a wiring A and a wiring B, and the wiring A and the wiring B are disposed in the same layer as each other in at least one portion of a display region of the display panel and are disposed in different layers than each other in at least one other portion of the display region.

7. The display panel of claim 6 ,

wherein interconnection lengths of the respective two wirings are equal to each other.

8. A display unit comprising:

a display panel including a substrate, a plurality of first wirings formed on the substrate extending in a row direction, a plurality of second wirings formed on the substrate extending in a column direction, and a plurality of pixels formed on the substrate and respectively arranged in proximity to intersections of the first wirings and the second wirings; and
