Display device having sub-pixels that share a horizontal power line

A display device comprising:

• a first pixel disposed on a substrate;
• a second pixel spaced apart from the first pixel in a first direction;
• a first vertical power line extending in the first direction and receiving a first power source;
• and
• a first horizontal power line extending in a second direction intersecting the first direction between the first pixel and the second pixel and receiving the first power source, wherein
• each of the first pixel and the second pixel includes a first sub-pixel, a second sub-pixel and a third sub-pixel sequentially disposed in the first direction,
• the first pixel includes a first common pattern disposed between the first sub-pixel of the first pixel and the second sub-pixel of the first pixel to extend in the second direction,
• the first sub-pixel of the first pixel and the second sub-pixel of the first pixel share the first common pattern and are electrically connected to the first vertical power line by way of the first common pattern, and
• the third sub-pixel of the first pixel and the first sub-pixel of the second pixel share the first horizontal power line and
• the first common pattern forms a channel area of a transistor of each of the first sub-pixel of the first pixel and the second sub-pixel of the first pixel.
