Disclosed is an organic light emitting diode (OLED) display device including a substrate including a pixel region and a boundary region outside the pixel region. The pixel region comprises an area having a short side and a long side. The pixel region comprises an array of pixels to emit light. The OLED display device includes a substrate in the pixel region and in the boundary region The OLED display device further includes a first electrode of a light emitting device in the pixel region over the substrate, a first bank covering edges of the first electrode in the pixel region on the substrate in the boundary region, wherein a width of an edge of the first bank along the short side of the pixel region is different from a width of an edge of the first bank along the long side of the pixel region, and a second bank on a portion of the first bank in the boundary region.
