Abstract: The present invention provides a display device that facilitates product inspection and maintenance. A button section is mounted to a back cabinet, and a power-source circuit board is fitted into a circuit-board fitting slit. Furthermore, the power-source circuit board is locked and fixed by a first circuit-board locking claw, and a main circuit board is locked and fixed by a second circuit-board locking claw. A speaker integrally assembled in a speaker holder is locked and fixed by a speaker locking claw, and thereafter a display panel is caused to be held by a display panel standing holding portion in a standing manner. The wire connection work of a display panel, each of the circuit boards, and the like is performed, the display panel is brought down and placed on a display panel placement portion, a front cabinet is mounted, and a leg portion is mounted to a leg-portion mounting portion.

Abstract: A cabinet-fixing locking nail and a locking stopper are formed at a fixing unit which is integrally attached to a button portion. The button portion is fixed to a back cabinet through the fixing unit, by locking the cabinet-fixing locking nail and the locking stopper to the back cabinet. A power circuit board is clipped to circuit board engagement slits which are guide grooves formed at the fixing unit and the button portion, and the power circuit board is locked by a first circuit board locking nail which is formed at the back cabinet to be fixed. The power circuit board and the button portion can be readily fixed only by a locking unit such as the cabinet-fixing locking nail, the locking stopper, the circuit board engagement slits the first circuit board locking nail and the like without using screw.
