Abstract: An organic light emitting diode display device includes a substrate, an active layer disposed on the substrate and including a metal oxide-based semiconductor, a gate electrode disposed on the active layer, an insulating layer disposed on the gate electrode, source and drain electrodes disposed on the insulating layer, a light emitting element on the source and drain electrodes, and a gate insulating layer between the active layer and the gate electrode. The gate insulating layer includes first and second gate insulating layers. The first gate insulating layer directly contacts the active layer and has a first amount of nitrogen. The second gate insulating layer is disposed on the first gate insulating layer and has a second amount of nitrogen that is different from the first amount of nitrogen.

Abstract: A thin film transistor substrate includes: a substrate; an oxide semiconductor layer disposed on the substrate; a gate electrode disposed on the substrate; a gate insulating layer interposed between the oxide semiconductor layer and the gate electrode; and a source electrode and a drain electrode connected to the oxide semiconductor layer, the source electrode and the drain electrode being spaced apart from each other. The gate insulating layer includes: a first gate insulating layer having an oxygen content lower than that of a stoichiometric composition; and a second gate insulating layer including a material substantially the same as a material which the first gate insulating layer may include, and having an oxygen content higher than that of the first gate insulating layer, and the first gate insulating layer and the oxide semiconductor layer directly contact each other.

Abstract: A display device, having relatively high side visibility and transmittance, includes a first substrate having a plurality of red, green, and blue pixel regions; a lower electrode disposed on the red, green, and blue pixel regions; and an upper electrode disposed on the red, green, and blue pixel regions. The upper electrode is insulated from the lower electrode, and includes a plurality of upper branch electrodes disposed on the lower electrode. A width and height of the upper branch electrode in at least one of the red, green, and blue pixel regions are respectively different from a width and a height of the upper branch electrode in another of the red, green and blue pixel regions.
