Abstract: An organic light emitting display device includes a substrate, an active layer, a gate electrode, a first high dielectric constant (hereinafter “high-k”) insulation structure, source and drain electrodes, and a light emitting structure. The active layer is disposed on the substrate. The gate electrode is disposed on the active layer. The first high-k insulation structure is disposed on the gate electrode and includes a carbon-doped first high-k insulation layer and a first ammonia layer on the carbon-doped first high-k insulation layer. The source and drain electrodes are disposed on the first high-k insulation structure and constitute a semiconductor element together with the active layer and the gate electrode. The light emitting structure is disposed on the source and drain electrodes.

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.
