Abstract: A display device includes a first thin film transistor disposed on a substrate. A first insulating interlayer covers the first thin film transistor. An active pattern is disposed on the first insulating interlayer. The active pattern includes indium-gallium-zinc oxide (IGZO) having a thickness in a range of about 150 Å to about 400 Å. A gate insulation layer covers the active pattern. A gate pattern is disposed on the gate insulation layer. A second insulating interlayer covers the gate pattern.

Abstract: A display device comprises a substrate; a circuit array layer comprising pixel drivers, data lines, first dummy lines, and second dummy lines; and a light emitting array layer. The display area comprises middle, first side, and second side regions. The data lines comprise first, second, and third data lines disposed in the middle, first side, and second side regions, respectively. The first dummy lines comprise a first data detour line disposed in the first side region and adjacent to a part of the second data line, and auxiliary lines. The second dummy lines comprise a second data detour line configured to connect the first data detour line to the third data line, and additional lines. The auxiliary lines comprise a bias auxiliary line to which a bias power is applied; and a second power auxiliary line to which a second power is applied.
