Abstract

A display panel including: a substrate; a pixel electrode disposed on the substrate; a pixel-defining layer having an opening, wherein the pixel-defining layer covers an edge of the pixel electrode, and the opening exposes a center of the pixel electrode; and a first line positioned between the substrate and the pixel electrode and having a first portion overlapping the pixel-defining layer and a second portion overlapping the opening, wherein, when viewed from a direction perpendicular to the substrate, a shape of the first portion differs from a shape of the second portion.

First claim

What is claimed is:

1 . A display panel comprising:
a substrate; a pixel electrode disposed on the substrate; a pixel-defining layer having an opening, wherein the pixel-defining layer covers an edge of the pixel electrode, and the opening exposes a center of the pixel electrode; and a first line positioned between the substrate and the pixel electrode and having a first portion overlapping the pixel-defining layer and a second portion overlapping the opening, wherein, when viewed from a direction perpendicular to the substrate, a shape of the first portion differs from a shape of the second portion.

2 . The display panel of claim 1 , wherein, when viewed from the direction perpendicular to the substrate, the first portion is straight in a direction in which the first line extends, and the second portion is curved.

3 . The display panel of claim 2 , wherein, when viewed from the direction perpendicular to the substrate, the second portion is a repeating curve.

4 . The display panel of claim 1 , further comprising a second line positioned between the substrate and the pixel electrode and having a third portion and a fourth portion, wherein the third portion overlaps the pixel electrode and the pixel-defining layer, the fourth portion overlaps the opening, and, when viewed from the direction perpendicular to the substrate, a shape of the third portion differs from a shape of the fourth portion.

5 . The display panel of claim 4 , wherein, when viewed from the direction perpendicular to the substrate, each of the first portion and the third portion is straight in a direction in which the first line extends, and each of the second portion and the fourth portion is curved.

6 . The display panel of claim 5 , wherein, when viewed from the direction perpendicular to the substrate, each of the second portion and the fourth portion is a repeating curve.

7 . The display panel of claim 5 , wherein the second portion has a first convex portion protruded in a direction toward the second line, and the fourth portion has a second convex portion protruded in a direction away from the first line.

8 . The display panel of claim 7 , wherein a first imaginary straight line passing through the first convex portion and perpendicular to the direction in which the first line extends is spaced apart from a second imaginary straight line passing through the second convex portion and perpendicular to the direction in which the first line extends.

9 . The display panel of claim 4 , wherein the second portion has first convex portions protruded in a direction toward the second line, and the fourth portion has second convex portions protruded in a direction away from the first line.

10 . The display panel of claim 9 , wherein first imaginary straight lines passing through the first convex portions and perpendicular to the direction in which the first line extends are spaced apart from second imaginary straight lines passing through the second convex portions and perpendicular to the direction in which the first line extends.

11 . The display panel of claim 10 , wherein the first imaginary straight lines and the second imaginary straight lines are alternately arranged in the direction in which the first line extends.

12 . The display panel of claim 4 , wherein the first line includes a driving voltage line and the second line includes a data line.

13 . The display panel of claim 4 , wherein, when viewed from the direction perpendicular to the substrate, the first line has a fifth portion that overlaps the opening and is spaced apart from the second portion in the opening, wherein the second portion and the fifth portion are connected to the first portion.

14 . The display panel of claim 13 , wherein, when viewed from the direction perpendicular to the substrate, each of the first portion and the third portion is straight in the direction in which the first line extends, and each of the second portion, the fourth portion, and the fifth portion is curved.

15 . The display panel of claim 14 , wherein, when viewed from the direction perpendicular to the substrate, each of the second portion, the fourth portion, and the fifth portion is a repeating curve.

16 . The display panel of claim 14 , wherein the second portion has a first convex portion protruded in a direction toward the second line, the fifth portion has a third convex portion protruded in the direction toward the second line, and the fourth portion has a second convex portion protruded in a direction away from the first line.

17 . The display panel of claim 16 , wherein a first imaginary straight line passing through the first convex portion and perpendicular to a direction in which the first line extends is spaced apart from a second imaginary straight line passing through the second convex portion and perpendicular to the direction in which the first line extends, and a third imaginary straight line passing through the third convex portion and perpendicular to the direction in which the first line extends coincides with the first imaginary straight line.

18 . The display panel of claim 14 , wherein the second portion has first convex portions protruded in a direction toward the second line, the fifth portion has third convex portions protruded in the direction toward the second line, and the fourth portion has second convex portions protruded in a direction away from the first line.

19 . An electronic apparatus comprising:
a display panel; and a lower cover constituting an exterior of the electronic apparatus and having an opening portion that exposes a portion of the display panel, wherein the display panel comprises: a substrate; a pixel electrode disposed on the substrate; a pixel-defining layer having an opening, wherein the pixel-defining layer covers an edge of the pixel electrode, and the opening exposes a center of the pixel electrode; and a first line positioned between the substrate and the pixel electrode and having a first portion overlapping the pixel-defining layer and a second portion overlapping the opening, wherein, when viewed from a direction perpendicular to the substrate, a shape of the first portion differs from a shape of the second portion.

20 . A display panel comprising:
a substrate; a pixel electrode disposed on the substrate; a pixel-defining layer configured to define an opening that exposes a portion of the pixel electrode, wherein the pixel-defining layer at least partially covers the pixel electrode; and a conductive line positioned between the substrate and the pixel electrode, the conductive line including a first region overlapping the pixel-defining layer and a second region overlapping the opening, wherein, in a plan view, the first region has a shape distinct from the shape of the second region.
