Abstract:
1. An organic light emitting diode display device comprising: a first electrode formed on a substrate; a reflective plate at a low portion of the first electrode to prevent light from being leaked onto the substrate, wherein the reflective plate is formed on every pixel region of the substrate; a partition wall having hydrophilicity and formed on the first electrode, the partition wall having a plurality of openings, wherein the partition wall is formed by a surface treatment using a material belonging to an amine group through pen like device, and the material belonging to the amine group is one of 3-aminopropyltrimethoxysilane and 3-aminopropyl-triethoxysilane; red, green and blue organic light emitting layers having hydrophobicity and formed on the plurality of openings of the partition wall, respectively, wherein each of the red, green and blue organic light emitting layers is formed to be thicker than the partition wall, wherein the partition wall having hydrophilicity attracts a material having hydrophilicity and pushes out a material having hydrophobicity so that the organic light emitting layers run onto the partition wall are not spread onto a neighboring organic light emitting layer; and a second electrode formed on each of the hydrophobic red, green and blue organic light emitting layers.
