Abstract: Disclosed is an organic light emitting diode display device. The disclosed organic light emitting diode display device includes an overcoat layer disposed on a substrate that is divided into an emissive area and a non-emissive area, and has multiple micro lenses in the emissive area and at least one depression in the non-emissive area. The organic light emitting diode display device further includes: a first electrode disposed on the overcoat layer, wherein the first electrode is disposed in the entire emissive area and in a part of the non-emissive area; a bank pattern disposed in the non-emissive area so as to be superposed on the depression; an organic light emitting layer disposed on the substrate; and a second electrode disposed on the organic light emitting layer. Accordingly, the organic light emitting diode display device may prevent light leakage.
