Abstract

A display device may include a substrate, a display area, a peripheral region, a driving circuit and a dummy wire. A display area formed on a side of the substrate and in which a plurality of pixels are provided. A peripheral region surrounds the display area. A driving circuit provided in the peripheral region, which provides a driving voltage to the plurality of pixels and includes a driving voltage terminal for receiving the driving voltage. A dummy wire portion provided in the peripheral region, separated from the display area with the driving circuit therebetween, and includes a plurality of dummy wires. The driving voltage terminal of the driving circuit is connected to at least one of the plurality of dummy wires.

First claim

What is claimed is:

1. A display device comprising:
a substrate;
a display area formed on the substrate and including a plurality of pixels;
a peripheral region surrounding the display area;
a driving circuit formed in the peripheral region, providing a driving voltage to the plurality of pixels, and including a driving voltage terminal for receiving the driving voltage; and
a wire portion formed in the peripheral region and including a plurality of wires, wherein each of the wires is connected to a ground terminal that provides a ground voltage each of the wires is extended lengthwise in a first direction,
wherein the driving circuit is between the display area and the wire portion,
wherein the driving voltage terminal includes:
a terminal body connected to the plurality of pixels; and
a plurality of protrusions protruding toward the wire portion from the terminal body,
wherein each of the protrusions is extended lengthwise in a second direction substantially perpendicular to the first direction, each of the protrusions overlaps a first wire of the plurality of wires, and each of the protrusions is connected to the first wire via a contact hole to connect the driving voltage terminal to the first wire, and wherein each of the protrusions is spaced apart from each other.

2. The display device of claim 1 , further comprising
a passivation layer for covering a part of the display area and the peripheral region,
wherein the passivation layer is made of a polyimide material and covers the driving voltage terminal, except for the plurality of protrusions.

3. The display device of claim 1 , wherein
the wire portion further includes a wire insulating layer for covering the plurality of wires, and
the driving voltage terminal is electrically connected to the plurality of wires through the contact holes passing through the wire insulating layer.

4. The display device of claim 3 , wherein
each of the plurality of protrusions is connected to one of the plurality of wires through a pair of the contact holes.

5. The display device of claim 1 , wherein the plurality of wires are separated by gaps.

6. The display device of claim 5 , wherein the gaps are formed in a wire insulating layer.
