摘要： 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.
