Abstract: An organic light emitting device includes: a first electrode disposed on a substrate; a pixel defining layer disposed on the substrate e and patterned so that at least a portion of the first electrode is exposed in a light emitting region; a hole injection layer disposed over the pixel defining layer and the at least a portion of the first electrode exposed in the light emitting region; an organic thin film layer disposed over the hole injection layer; an electron injection layer disposed over the organic thin film layer; and a second electrode disposed on the electron injection layer, the second electrode having an opening configured to expose the electron injection layer in the light emitting region. The organic light emitting device may be implemented in a display device having excellent color-reproduction, when applied to the display device using white light as a light source and the large area display device.
