Disclosed is a display device that may include a thin film transistor array substrate that includes a plurality of first sub-pixels and a plurality of second sub-pixels, wherein one of the plurality of first sub-pixels includes a first emission region and a first non-emission region, and one of the plurality of second sub-pixels includes a second emission region and a second non-emission region; a first bank pattern in the first and second non-emission regions, the first bank pattern including a hydrophilic material; and a second bank pattern on an upper surface of the first bank pattern, the second bank pattern includes a hydrophobic material.

Thin film transistor array substrate and method of fabricating the same

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.
