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.

Abstract: An AV device comprises a processing section for carrying out a process for view and listening, a signal output section for outputting a signal to the processing section, first signal input sections including a mobile audio input terminal, a first detecting section for detecting insertion/removal of a plug into/from the mobile audio input terminal, and a first control section for controlling the connection between the first signal input sections and the signal output section according to the result of the detection by the first detection section. Another AV device is provided in which insertion/removal of a plug into/from a second signal input section and indication information is outputted to a second video display section according to the detection result. With such constitutions, various processings can be carried out according to insertion/removal of a plug.
