ORGANIC LIGHT EMITTING DIODE DISPLAY AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: An organic light emitting diode display device and a manufacturing method thereof are provided to precisely control the growth of a first crystallization area by an inclination thickness part of an insulating layer pattern, thereby effectively crystallizing a part of a crystallization semiconductor layer used in one thin film transistor. CONSTITUTION: An insulating layer pattern(120) is formed on a substrate body(111). The insulating layer pattern includes a first thickness part(121) and a second thickness part(122) thinner than the first thickness part. A polycrystalline semiconductor layer(130) is formed on the insulating layer pattern. The polycrystalline semiconductor layer is classified into a first crystallization area(131) and the second crystallization area(132). The second crystallization area is crystallized into a solid phase.
