摘要： An Organic Light Emitting Display (OLED) and its fabrication method has a pixel defining layer provided on a first electrode which is formed with a gas vent groove to allow gas to vent when the pixel defining layer is being formed, so that gas is not left in a pixel but vented when a donor film is laminated by a Laser-Induced Thermal Imaging (LITI) method, thereby decreasing edge open failures.

摘要： A method of fabricating an OLED is provided. The method includes providing a substrate, in which a pixel electrode is formed. In addition, the method includes laminating a donor substrate attached to a frame on an entire surface of the substrate, and irradiating a laser to a predetermined region of the donor substrate to form an organic layer pattern on the pixel electrode. The present invention provides a method of fabricating the OLED capable of suppressing generation of contaminants such as particles and so on, and preventing the donor substrate from sagging or bending, as well as improving transfer efficiency since the donor substrate and the substrate are readily adhered to each other to maintain vacuum state.
