A flat panel display capable of preventing a pixel circuit from electrically short-circuiting, and a method of manufacturing the flat panel display are disclosed. In one embodiment, the flat panel display includes an insulating film (120) having an aperture (121), a pixel electrode (131) having a portion exposed by the aperture of the insulating film, a conductor (140) formed on the insulating film (120), and a capping layer (150) covering the conductor. According to embodiments of the present invention, the conductor is formed from a conductive paste and the rough surface of the conductive paste is passivated by a capping layer formed on the conductor, and thus, a short circuit between the conductor and an opposing pixel electrode can be prevented.
