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

1. A display panel comprising:

a display region including an array of a plurality of pixels each constituted by a sub-pixel; and

a frame region provided around the display region,

wherein a plurality of pixels located in a contour section of the display region include a pixel lacking at least one sub-pixel on a side of the frame region, and

the contour section of the display region is defined by a plurality of sub-pixels arranged stepwise by single sub-pixel units.

11. A display device comprising

the display panel according to claim 1.

2. A display panel comprising

a display region including an array of a plurality of pixels each constituted by a plurality of sub-pixels,

wherein a contour section of the display region is defined by a plurality of pixels arranged stepwise by single pixel units.

12. A display device comprising

the display panel according to claim 2.

3. 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 the 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 a side of a frame region; and

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

4. The display panel according to claim 3,

wherein the sub-pixels constituting the pixel for a contour have similar aperture shapes to one another.

5. The display panel according to claim 3,

wherein the sub-pixels constituting the pixel for a contour have different aperture shapes from one another.

6. The display panel according to claim 3,

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

the sub-pixels constituting the plurality of pixels for a contour have aperture regions having similar aperture areas to one another in respective pixels for 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 for a contour vary stepwise along the contour of the display region.

7. The display panel according to claim 3 further comprising a light-shielding member,

wherein the light-shielding member defines the aperture area of each of the sub-pixels constituting the pixel for a contour.

8. The display panel according to claim 7,

wherein the display panel comprises a substrate, and

the light-shielding member is a black matrix provided on the substrate.

9. The display panel according to claim 7,

wherein the display panel comprises a substrate and a wiring provided on the substrate, and

the light-shielding member comprises the same layer as the wiring.

10. The display panel according to claim 3,

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

the pixel electrode defines the aperture area of each of the sub-pixels constituting the pixel for a contour.

13. A display device comprising

the display panel according to claim 3.
