ABSTRACT:
A flat panel display includes a pixel electrode having an opening portion formed on an insulating substrate, a semiconductor layer formed over a surface of the insulating substrate, spaced apart from the pixel electrode, having source and drain regions formed to both end portions thereof, a first insulating layer formed over the surface of the insulating substrate excluding the opening portion of the pixel electrode, a gate electrode formed on the first insulating layer over the semiconductor layer, and a second insulating layer formed over the surface of the insulating substrate excluding the opening portion of the pixel electrode. The present invention provides an organic EL display manufactured with reduced mask processes which has excellent electrical characteristics and improved light transmittance.
