An organic light emitting diode display device comprises a substrate including a pixel region, the pixel region including a first portion and a second portion, a first electrode in the second portion of the pixel region, a bank layer separating the first portion and the second portion of the pixel region, an emitting layer in the second portion of the pixel region but not in the first portion of the pixel region, an emission assisting layer extending in the first portion of the pixel region and in the second portion of the pixel region, the emission assisting layer in the first portion of the pixel region being more conductive than the emission assisting layer in the second portion of the pixel region, and a second electrode on the emission assisting layer in the first portion of the pixel region and in the second portion of the pixel region.
