Abstract

A display device includes a plurality of signal lines formed in a display area, a pixel array connected to the plurality of signal lines and including a plurality of pixels arranged in a matrix, a scan driving circuit and a data driving circuit formed in a non-display area and electrically connected to the plurality of signal lines, and a dummy pattern formed in the non-display area in a position adjacent to the pixel array along an outer boundary of the pixel array. The dummy pattern is formed to be parallel to a first pixel in a position spaced apart from the first pixel located at an edge of the pixel array in the non-display area by a predetermined distance.

First claim

What is claimed is:

1 . A display device comprising:
a plurality of signal lines formed in a display area; a pixel array connected to the plurality of signal lines, the pixel array including a plurality of pixels; a scan driving circuit and a data driving circuit located in a non-display area and electrically connected to the plurality of signal lines; and a dummy pattern formed in the non-display area in a position adjacent to the pixel array along an outer boundary of the pixel array, wherein the dummy pattern is formed to be parallel to a first pixel in a position spaced apart from the first pixel located at an edge of the pixel array in the non-display area by a predetermined distance.

2 . The display device of claim 1 , wherein:
the predetermined distance is the same as a distance between pixel patterns adjacent to each other in two pairs of adjacent pixels.

3 . The display device of claim 1 , wherein:
a thickness of the dummy pattern is the same as a thickness of the adjacent pixel patterns in the two pairs of pixels.

4 . The display device of claim 1 , wherein:
the dummy pattern includes a first dummy pattern formed at an outer boundary region between the pixel array and the scan driving circuit, and a second dummy pattern formed at an outer boundary between the pixel array and the data driving circuit.

5 . The display device of claim 4 , wherein:
the first dummy pattern and the second dummy pattern are formed on the same layer.

6 . The display device of claim 4 , wherein:
the first dummy pattern and the second dummy pattern are formed on different layers to be electrically connected to each other in the form of a bridge.

7 . The display device of claim 5 , wherein:
the first dummy pattern and the second dummy pattern are formed in any one of an active layer, a gate layer, and a data metal layer included in the organic light emitting device.

8 . The display device of claim 6 , wherein:
the first dummy pattern and the second dummy pattern are formed in any one of an active layer, a gate layer, and a data metal layer included in the organic light emitting device.

9 . The display device of claim 1 , wherein:
both ends of a wiring line included in the dummy pattern are connected to a ground wiring line or a power wiring line to be used as a static electricity shielding circuit.

10 . The display device of claim 1 , wherein:
a static electricity diode circuit is connected to a wiring line included in the dummy pattern.
