## Abstract

A display device includes a substrate including a display area in which a plurality of pixels is disposed, and a non-display area in a peripheral area of the display area; an insulating layer disposed on the substrate; a metal wiring disposed on the substrate; and a plurality of dummy patterns disposed in the non-display area of the substrate. The plurality of dummy patterns includes a plurality of first patterns including an insulating material and a plurality of second patterns including a metal material.

## Claims

### Claim 1

A display device comprising:
a substrate including:
a display area on which a plurality of pixels is disposed, and
a non-display area near the display area;
a metal wiring disposed on the substrate and including at least one of a gate electrode layer, a source electrode layer and a drain electrode layer;
an insulating layer including a first insulating layer and a second insulating layer on the substrate; and
a plurality of dummy patterns disposed on a surface of the non-display area of the substrate,
wherein the plurality of dummy patterns includes a plurality of first patterns formed of the same material as the insulating layer, and a plurality of second patterns formed of the same material as the metal wiring,
wherein the plurality of first patterns and the plurality of second patterns are disposed on the non-display area adjacent to one side of the display area, and
wherein the plurality of first patterns and the plurality of second patterns are spaced apart from each other in a plane parallel to the surface of the non-display area of the substrate and none of the plurality of first patterns overlap any of the plurality of second patterns in a direction perpendicular to the surface of the substrate.
