Abstract: Provided is a flat-panel display for improving a structure of a shape of a through-hole of a backlight cover that is a resin-made member, which is passed through when making a PWB contact a metal plate member, so that a gasket can be mechanically fixed. This flat-panel display includes: a metal plate member (30) arranged on a rear side of a display panel; a non-conductive plate member (20) arranged so as to face a rear side of the metal plate member (30) and including a through-hole (42); a circuit board (50) arranged so as to face a rear side of the non-conductive plate member (20) ; and a gasket (90) arranged in the through-hole (42) and holding conduction of the metal plate member (30) and the circuit board (50), in which the non-conductive plate member (20) includes a gasket fixation portion (44) formed around the through-hole (42) in a convex shape.
