Abstract
Provided is a thin film transistor having an oxide semiconductor material for an organic light emitting diode display and a method for manufacturing the same. The organic light emitting diode display includes a gate electrode formed on a substrate; a gate insulating layer formed on the gate electrode; a semiconductor layer formed on the gate insulating layer to overlap with the gate electrode, and including a channel area and source and drain areas which extend from the channel area to both outsides, respectively and are conductorized; an etch stopper formed on the channel area and exposing the source area and the drain area; a source electrode contacting portions of the exposed source electrode; and a drain electrode contacting portions of the exposed drain electrode.
