Abstract

See full text

An embodiment of a display device includes a substrate, a semiconductor layer, a first gate insulating layer, a gate electrode, a second gate insulating layer, a first storage electrode, a first interlayer insulating layer, a second interlayer insulating layer, a data line, and a driving voltage line. The semiconductor layer is disposed on the substrate. The first gate insulating layer is disposed on the semiconductor layer. The gate electrode is positioned on the first insulating layer. The second gate insulating layer is disposed on the gate electrode. The first storage electrode is positioned on the second gate insulating layer. The first interlayer insulating layer is disposed on the first storage electrode and has an opening surrounding the semiconductor layer, the gate electrode, and the first storage electrode. The second interlayer insulating layer is disposed on the first interlayer insulating layer and fills the opening. The data line and the driving voltage line are positioned on the second interlayer insulating layer. The semiconductor layer, the gate electrode, and the storage electrode are included in a pixel region. The display device includes a plurality of pixel regions. The data line and the driving voltage line cross the pixel circuit region. A portion of the semiconductor layer is in contact with the second interlayer insulating that fills the opening.
