A flat panel display has an insulating substrate at the upper part of which a pixel electrode is equipped; an opaque conductive film formed on the front surface of the insulating substrate except at the pixel electrode; an insulating film equipped with a contact hole exposing a portion of the opaque conductive film; and a thin film transistor equipped with a gate electrode, and conductive patterns for source/drain electrodes connected to the opaque conductive film through the contact hole.
