Abstract

A display panel having at least one hole inside a display area includes: a substrate; a plurality of display elements arranged in a plane around the at least one hole; and a plurality of signal lines extending in a first direction, wherein the at least one hole includes a first hole having a first width in a second direction and having two sides with asymmetric shapes with respect to a first central line passing through a center of the first width, wherein each of first and second neighboring signal lines extends in the first direction, the first signal line detours around a first side of the first hole, and the second signal line detours around a second side of the first hole opposite to the first side, and wherein the first and second signal lines are asymmetric with respect to a first virtual line therebetween.

First claim

What is claimed is:

a substrate having an upper surface and a lower surface opposite to the upper surface, wherein the substrate has a first hole and a second hole each passing from the upper surface to the lower surface; a plurality of display elements on the upper surface of the substrate, the plurality of display elements being arranged two-dimensionally around the first hole and the second hole; and a plurality of signal lines electrically connected to the plurality of display elements and extending in a first direction, wherein the first hole has a first width in a second direction crossing the first direction, the first width being between a first portion of a perimeter of the first hole and a second portion of the perimeter of the first hole, the first hole includes a first side and a second side that are asymmetric with respect to a first central line passing through a center of the first width along the first direction, wherein the plurality of signal lines comprises a first signal line, detouring around the first side of the first hole, and a second signal line detouring around the second side of the first hole, and wherein a first distance between the first portion of the perimeter of the first hole and a detouring portion of the first signal line is the same as a second distance between the second portion of the perimeter of the first hole and a detouring portion of the second signal line.

2 . The display panel of the claim 1 , wherein a portion of the first side of the first hole has a first radius of curvature, and a portion of the second side of the first hole has a second radius of curvature that is different from the first radius of curvature.

3 . The display panel of the claim 2 , wherein the first radius of curvature is greater than the second radius of curvature.

4 . The display panel of the claim 1 , wherein the second hole has a second width in the second direction, the second hole having two sides that are symmetric with respect to a second central line passing through a center of the second width along the first direction.

5 . The display panel of the claim 4 , wherein the first width is greater than the second width.

6 . The display panel of the claim 1 , wherein the second hole has a second width in the second direction, and a shape of the first hole and a shape of the second hole are different from each other.

7 . The display panel of the claim 1 , wherein the first width is a greatest width of the first hole along the second direction.

8 . A display panel, the display panel comprising:
a substrate having an upper surface and a lower surface opposite to the upper surface, wherein the substrate has a first hole and a second hole each passing from the upper surface to the lower surface; a plurality of display elements on the upper surface of the substrate, the plurality of display elements being arranged two-dimensionally around the first hole and the second hole; and a plurality of signal lines electrically connected to the plurality of display elements and extending in a first direction, at least one of the plurality of signal lines detouring around the first hole, wherein the first hole has a first width in a second direction crossing the first direction, the second hole has a second width in the second direction, and the first width is greater than the second width, wherein the first hole includes a first side and a second side opposite to the first side with respect to a first central line passing through a center of the first width along the first direction, a first portion of the first side of the first hole has a first radius of curvature, and a second portion of the second side of the first hole has a second radius of curvature that is different from the first radius of curvature, wherein the plurality of signal lines comprises a first signal line, detouring around the first side of the first hole, and a second signal line detouring around the second side of the first hole, and wherein a portion of the first signal line extending around the first portion of the first side and a portion of the second signal line extending around the second portion of the second side of the first hole are asymmetric with respect to the first central line.

9 . The display panel of the claim 8 , wherein a shape of the first hole and a shape of the second hole are different from each other.

10 . The display panel of the claim 8 , wherein the first side and the second side are asymmetric with respect to the first central line.

11 . The display panel of the claim 10 , wherein the first radius of curvature is greater than the second radius of curvature.

12 . The display panel of the claim 8 , wherein the second hole has two sides that are symmetric with respect to a second central line passing through a center of the second width along the first direction.

13 . The display panel of the claim 8 , wherein a first distance between the first side of the first hole and a detouring portion of the first signal line is the same as a second distance between the second side of the first hole and a detouring portion of the second signal line.

14 . The display panel of the claim 8 , wherein the first width is a greatest width of the first hole along the second direction, the first signal line is closest to the first side of the first hole from among the plurality of signal lines, and the second signal line is closest to the second side of the first hole from among the plurality of signal lines.

15 . An electronic apparatus comprising:
a display panel having a first hole and a second hole spaced from the first hole; and at least one component corresponding to at least one of the first hole or the second hole of the display panel, wherein the display panel comprises:
a substrate having an upper surface and a lower surface opposite to the upper surface, wherein the first hole and the second hole each pass from the upper surface to the lower surface of the substrate;
