Abstract

A display panel includes: a substrate including a main display area, a component area, and a peripheral area; a main sub-pixel and a main pixel circuit, the main sub-pixel being in the main display area on the substrate, and the main pixel circuit being connected to the main sub-pixel; a plurality of auxiliary sub-pixels in the component area on the substrate; a plurality of auxiliary pixel circuits in the peripheral area on the substrate; a plurality of connecting lines connecting the plurality of auxiliary sub-pixels to the plurality of auxiliary pixel circuits, respectively; and a dummy line extending in a direction in which the plurality of connecting lines extend in the component area.

First claim

What is claimed is:

1. A display panel comprising:
a substrate including a main display area, a component area, and a peripheral area;
a main sub-pixel and a main pixel circuit, the main sub-pixel being in the main display area on the substrate, and the main pixel circuit being connected to the main sub-pixel;
a plurality of auxiliary sub-pixels in the component area on the substrate;
a plurality of auxiliary pixel circuits in the peripheral area on the substrate; and
a plurality of connecting lines connecting the plurality of auxiliary sub-pixels to the plurality of auxiliary pixel circuits, respectively;
wherein the plurality of connecting lines include a first connecting line and a second connecting line adjacent to each other, and include portions having different intervals from each other between centers of the first connecting line and the second connecting line in the component area.

2. The display panel of claim 1 , wherein the first connecting line has a first width and a second width that are different from each other.

3. The display panel of claim 1 , wherein the first connecting line and the second connecting line each include a bent portion.

4. The display panel of claim 1 , wherein the first connecting line and the second connecting line are each comprise a plurality of first connecting lines and a plurality of second connecting lines, respectively,
the plurality of first connecting lines are at a different layer from the plurality of second connecting lines, and
at least one of the plurality of first connecting lines is between two adjacent second connecting lines from among the plurality of second connecting lines.

5. The display panel of claim 4 , wherein the plurality of first connecting lines at least partially overlap the plurality of second connecting lines.

6. The display panel of claim 1 , wherein, among the plurality of auxiliary sub-pixels, an auxiliary sub-pixel emitting light of a same color as the main sub-pixel has a size greater than a size of the main sub-pixel.

7. The display panel of claim 1 , further comprising additional connecting lines connecting the plurality of connecting lines to the plurality of auxiliary pixel circuits, wherein the additional connecting lines include a material different from a material in the connecting lines.
