Organic light emitting diode display
First Claim
1. An organic light emitting diode display comprising:
- a substrate including a display area and a non-display area;
a display unit formed in the display area, the display unit including a plurality of subpixels arranged in a matrix form;
a main ground line that is formed to surround the non-display area and is formed using the same material as source and drain electrodes of a transistor unit included in each subpixel; and
an auxiliary ground line that is formed to surround the non-display area, overlaps at least a portion of the main ground line at a first side of the non-display area, is electrically connected to the main ground line, and is formed using the same material as a lower electrode of the organic light emitting diode included in each subpixel,wherein the material of the ground line is different from the material of the auxiliary ground line.
