Laser induced thermal imaging method, method of patterning organic layer using the same and method of fabricating organic light emitting diode display device using the same

A method of patterning an organic layer, comprising:

• preparing a substrate including an organic layer;
• preparing a donor substrate including a base layer and a light-to-heat conversion layer disposed on the base layer;
• aligning the substrate with the donor substrate;
• and
• irradiating laser to the base layer of the donor substrate,
• wherein the laser is irradiated to the base layer in a region excluding a region corresponding to a pattern to be formed on the substrate.

A method of manufacturing an organic light emitting diode (OLED) display device, comprising:

• forming a first electrode layer on a substrate;
• forming an insulating layer on the first electrode layer to define a first pixel region, a second pixel region, and a third pixel region;
• applying a first light-emitting material to the entire surface of the substrate including the first, second and third pixel regions;
• preparing a donor substrate including a base layer and a light-to-heat conversion layer disposed on the base layer;
• aligning the substrate with the donor substrate;
• and
• irradiating a laser to the base layer of the donor substrate,
• wherein the laser is irradiated to the base layer in a region excluding a region corresponding to the first pixel region.
