Abstract

An electronic device includes a display panel that includes a plurality of light emitting elements, and an input sensor disposed on the display panel and that includes a plurality of mesh patterns. The mesh patterns include a plurality of openings formed therein and spaced apart from each other in a first direction and a second direction that crosses the first direction. The mesh patterns include a plurality of conductive patterns spaced apart from each other in a direction that cross the first and second directions, where a center opening of the plurality of openings is disposed therebetween, and a plurality of mesh lines disposed along an edge of the center opening and connected to the conductive patterns. Each of the conductive patterns includes at least one cut-away portion opened toward one of the openings.

a plurality of openings formed therein and that are spaced apart from each other in a first direction and a second direction that crosses the first direction;
a plurality of conductive patterns that are spaced apart from each other in a direction crossing the first and second directions, wherein a center opening of the openings is disposed therebetween; and
a plurality of mesh lines disposed along an edge of the center opening and connected to the conductive patterns, wherein each of the conductive patterns includes a cut-away portion that opens toward one of the openings.

2 . The electronic device of claim 1 , wherein the conductive patterns comprise:
first and second conductive patterns spaced apart from each other in a third direction that crosses the first and second directions wherein the center opening is disposed therebetween; and third and fourth conductive patterns spaced apart from each other in a fourth direction substantially perpendicular to the third direction wherein the center opening is disposed therebetween, and wherein the mesh lines comprise: first mesh lines that extend in the first direction and connect the first conductive pattern to the third conductive pattern or connect the second conductive pattern to the fourth conductive pattern; and second mesh lines that extend in the second direction and connect the first conductive pattern to the fourth conductive pattern or connect the second conductive pattern to the third conductive pattern.

3 . The electronic device of claim 2 , wherein each of the first conductive pattern and the second conductive pattern includes the cut-away portion that opens toward the center opening.

4 . The electronic device of claim 3 , wherein at least one of the cut-away portion of the third conductive pattern or the cut-away portion of the fourth conductive pattern opens toward the center opening.

5 . The electronic device of claim 3 , wherein the cut-away portion of the third conductive pattern and the cut-away portion of the fourth conductive pattern open toward different openings.

6 . The electronic device of claim 2 , wherein the cut-away portion of the first conductive pattern and the cut-away portion of the second conductive pattern open toward different openings.

7 . The electronic device of claim 2 , wherein the center opening overlaps one of the plurality of light emitting elements, and a shortest separation distance between the one light emitting element and the conductive patterns is equal to a shortest separation distance between the one light emitting element and the mesh lines, when viewed in a plan view.

8 . The electronic device of claim 1 , wherein each of the conductive patterns includes one cut-away portion.

9 . The electronic device of claim 1 , wherein at least one of the conductive patterns includes a plurality of cut-away portions that open toward different openings.

10 . The electronic device of claim 1 , wherein the conductive patterns comprise:

11 . The electronic device of claim 1 , wherein the openings have a same size as each other when viewed in a plan view.

12 . The electronic device of claim 1 , wherein the openings include two or more openings that have different sizes, when viewed in a plan view.

13 . The electronic device of claim 2 , wherein the openings comprise:
first and second openings that are spaced apart from each other in the first direction wherein the center opening is disposed therebetween; and third and fourth openings that are spaced apart from each other in the second direction wherein the center opening is disposed therebetween, wherein each of the center opening, the first opening, the second opening, the third opening, and the fourth opening overlaps the light emitting elements, respectively.

14 . The electronic device of claim 13 , wherein a light emitting element that overlaps the center opening emits light that has a color that differs from those of light emitting elements that overlap the first to fourth openings.

15 . The electronic device of claim 13 , wherein a light emitting element that overlaps the first opening and a light emitting element that overlaps the second opening emit a same color light as each other.

16 . The electronic device of claim 13 , wherein cut-away portions of the first to fourth conductive patterns open toward the first opening or the second opening, and a light emitting element that overlaps the center opening emits light having a wavelength shorter than a wavelength of light emitted from a light emitting element that overlaps the first opening.

17 . The electronic device of claim 16 , wherein the light emitting elements that overlap the third and fourth openings, respectively, emit light that has colors that different from those of light emitted from the light emitting elements that overlap the first and second openings, respectively.

18 . The electronic device of claim 13 , wherein cut-away portions of the first to fourth conductive patterns open toward the first opening or the second opening, and a size of the center opening is less than a size of the first opening and a size of the second opening, when viewed in a plan view.

19 . The electronic device of claim 18 , wherein each of a size of the third opening and a size of the fourth opening is greater than the size of the first opening.

20 . An electronic device, comprising:
