Abstract: An OLED device includes a substrate, a first active layer, a first gate electrode, a second gate electrode, first source and first drain electrodes, a first high dielectric constant (high-k) insulation structure, and a light emitting structure. The substrate has a first region and a second region. The first active layer is disposed in the first region on the substrate. The first gate electrode is disposed on the first active layer, and has a first thickness. The second gate electrode is disposed on the first gate electrode. The first source electrode and first drain electrode are disposed on the second gate electrode, and constitutes a first semiconductor element together with the first active layer and the first gate electrode. The first high-k insulation structure is disposed between the first gate electrode and the second gate electrode, and is spaced apart from the first source electrode and first drain electrode.

Abstract: A display device includes a thin film transistor, a gate insulting layer, an interlayer insulating layer, a data line, a spacer, and a pixel. The thin film transistor includes a semiconductor layer and a gate electrode. The semiconductor layer includes a source region and a drain region on respective sides of the channel region. The gate insulating layer is between the semiconductor layer and the gate electrode. The interlayer insulating layer covers the thin film transistor. The data line contacts the semiconductor layer via a hole passing through the gate insulating layer and the interlayer insulating layer. The spacer is on an inner wall of the hole and contacting the data line. The pixel electrode is electrically connected to the thin film transistor.
