Abstract: Disclosed is an organic light emitting display having reduced thickness and weight. The organic light emitting display with a touch sensor removes the necessity of an additional adhesion process by directly forming a touch sensor including a touch sensing line and a touch driving line and a color filter on the encapsulation layer covering a light emitting device, thereby simplifying a manufacturing process and reducing manufacturing costs.

Abstract: A method for manufacturing a semiconductor device is discussed. The method includes forming a gate electrode on a substrate, forming a gate insulating film over the substrate, depositing an In—Ga—Zn oxide over the gate insulating film while heating the substrate to a temperature of 200 to 300° C., an atomic percent ratio of Zn in the In—Ga—Zn oxide as-deposited being higher than that of In or Ga, heat-treating the deposited In—Ga—Zn oxide at a temperature of 200 to 350° C., thereby forming an active layer crystallized throughout an entire thickness of the active layer, and forming a source electrode and a drain electrode.
