THIN FILM TRANSISTOR, METHOD OF MANUFACTURING THE SAME, AND ORGANIC LIGHT EMITTING DISPLAY DEVICE INCLUDING THE SAME

PROBLEM TO BE SOLVED: To provide a thin film transistor that solves a problem of an arc generated in a process of crystallizing an amorphous silicon layer with conducted heat of a metal film, to provide a method of manufacturing the same, and to provide an organic light emitting display device including the same. SOLUTION: The thin film transistor includes: a substrate having a pixel portion and an interconnection portion; a buffer layer positioned on the substrate; a gate electrode positioned on the buffer layer and positioned at the pixel portion; a gate interconnection positioned at the interconnection portion; a gate insulating film positioned over the entire surface of the substrate; a semiconductor layer positioned on the gate electrode; a source/drain electrode electrically connected to the semiconductor layer; and a metal pattern positioned on the gate interconnection. There are also provided the method of manufacturing the same and the organic light emitting display device including the thin film transistor. COPYRIGHT: (C)2010,JPO&INPIT
