Summary:A method of forming an organic light emitting diode (OLED) display device is discussed. The method according to an embodiment includes forming a first bank pattern on a substrate and in an emission region and a non-emission region; forming a second bank pattern on the first bank pattern; forming an organic emission layer on the substrate in the emission region; and forming a planarization film on the substrate to include an opening under the first and second bank patterns in the non-emission region. The second bank pattern is on the first bank pattern in the non-emission region, and the first bank pattern is in the opening of the planarization film in the non-emission region.
