Abstract

A display device includes: a pixel part in which sub-pixels are disposed, and at least one transparent part disposed in an area adjacent to the pixel part. The at least one transparent part passes external light therethrough. The pixel part may include: first, second, third and fourth extension parts extending in directions different from each other and including wires; and first, second, third and fourth circuit parts. Each of the first, second, third and fourth circuit parts is disposed between adjacent pairs of the first, second, third and fourth extension parts and includes circuit elements of a respective sub-pixel of the sub-pixels.

first, second, third and fourth circuit parts, each of the first, second, third and fourth circuit parts being disposed between a respective adjacent pair of the first, second, third and fourth extension parts and including circuit elements of a respective sub-pixel of the sub-pixels, and
wherein each of the first, second, third and fourth circuit parts has a three sided shape, the three sided shape including:
a first side in contact with one of the first, second, third and fourth extension parts adjacent thereto;
a second side in contact with another of the first, second, third and fourth extension parts adjacent thereto; and
a third side in contact with the transparent part.

2. The display device of claim 1 , wherein
each of the first, second, third and fourth extension parts has shape symmetrical to others of the first, second, third and fourth extension parts adjacent thereto relative to a first axis and a second axis, the second axis being intersecting with the first axis, and
each of the first, second, third and fourth circuit parts has shape symmetrical to others of the first, second, third and fourth circuit parts adjacent thereto relative to the first axis and the second axis.

3. The display device of claim 1 , wherein a length of the third side is longer than a length of a fourth side, the fourth side being located at a respective extension part of the first, second, third and fourth extension parts and being in contact with the at least one transparent part.

4. The display device of claim 1 , wherein distances between each of the first, second, third and fourth extension parts and a center of a respective transparent part adjacent thereto are substantially the same.

5. The display device of claim 1 , wherein the at least one transparent part is surrounded in part by the third side of the circuit part and those of the first, second, third and fourth extension parts adjacent to the circuit part.

6. The display device of claim 1 , wherein the wires comprise:
at least one first power line configured to apply a first potential drive voltage to the sub-pixels, and
