Display device

A display device comprising:

• a base substrate comprising a front surface having an active area and a peripheral area, and a rear surface opposite to the front surface;
• a plurality of pixels on the active area;
• a plurality of first signal lines on the active area, the first signal lines extending in a first direction, spaced apart from each other in a second direction crossing the first direction, and connected to the pixels;
• a plurality of second signal lines on the active area, crossing the first signal line in an insulation manner, and connected to the pixels;
• a plurality of first conductive patterns on the peripheral area, spaced apart from each other in the first direction, and connected to the second signal lines;
• a second conductive pattern overlapping the first conductive patterns on a plane in the peripheral area and having a top surface waved in the first direction;
• and
• an optical member on the second conductive pattern and overlapping the active area and the peripheral area,
• wherein the top surface of the second conductive pattern comprises flat portions and protruding portions that are alternately arranged in the first direction, and the protruding portions protrude from the flat portions toward the optical member, and
• a gap between the protruding portions in the first direction is about 1.5 μm.
