Abstract
An organic light emitting diode (OLED) display apparatus, including a substrate, at least one thin film transistor (TFT) on the substrate, an insulating layer covering the at least one TFT and having a via hole and a groove, a first electrode on the insulating layer and electrically connected to the at least one TFT through the via hole, a pixel define layer on the first electrode and the groove, the pixel define layer having an opening that exposes the first electrode; an intermediate layer electrically connected to the first electrode through the opening, the intermediate layer including an organic emissive layer, and a second electrode on the intermediate layer. The organic emissive layer may be easily formed in the opening because a step between the organic emissive layer and the pixel define layer may be reduced as a portion of pixel define layer fills the groove.
