Abstract

The present invention provides an irregularly-shaped display panel having a display region with a contour section having a good appearance, which is easily designed and produced. The present invention is a display panel comprising a display region including: an array of a plurality of pixels each constituted by a plurality of sub-pixels; and a plurality of wirings provided along boundaries of the plurality of sub-pixels, wherein a plurality of pixels include a pixel for a contour located in a contour section of the display region; the sub-pixels constituting the pixel for a contour have aperture regions having similar aperture areas to one another and contour lines each running in parallel with a drawing direction of one of the wirings at least on the side of a frame region; and the aperture area of the pixel for a contour is smaller than an aperture area of a pixel located at an inner side of the contour section of the display region.

Claims (22)

1. A display panel comprising:

a display region including:

an array of a plurality of pixels each including a plurality of sub-pixels; and

a plurality of wirings provided along boundaries of the plurality of sub-pixels;

wherein the plurality of pixels include a pixel of a contour located in a contour section of the display region;

the sub-pixels included in the pixel of a contour have aperture regions having similar aperture areas to one another and contour lines each running in parallel with a drawing direction of one of the wirings at least on a side of a frame region;

the aperture area of the pixel of a contour is smaller than aperture area of a pixel located at an inner side of the contour section of the display region;

the display panel includes a light-shielding member, the light-shielding member defining an aperture area of each of the sub-pixels included in the pixel of a contour;

the display panel includes a substrate and a wiring layer of a scanning line or a data signal line provided on the substrate; and

the light-shielding member is provided by the same wiring layer as the scanning line or the data signal line.

2. The display panel according to claim 1 ,

wherein the sub-pixels included in the pixel of a contour have similar aperture shapes to one another.

3. The display panel according to claim 1 ,

wherein the sub-pixels included in the pixel of a contour have different aperture shapes from one another.

4. The display panel according to claim 1 ,

wherein the plurality of pixels include a plurality of the pixels of a contour located in a contour section of the display region;

the sub-pixels included in the plurality of pixels of a contour have aperture regions having similar aperture areas to one another in respective pixels of a contour and contour lines each running in parallel with a drawing direction of one of the wirings at least on a side of a frame region; and

aperture areas of the plurality of the pixels of a contour vary stepwise along the contour of the display region.

5. The display panel according to claim 1 ,

wherein the display panel includes a pixel electrode provided on the substrate, and

the pixel electrode defines the aperture area of each of the sub-pixels included in the pixel of a contour.

6. A display device comprising the display panel according to claim 1 .
