Abstract
A display apparatus includes a rear chassis configured to support a liquid crystal display panel and a backlight assembly; a vibration region formed as a part of the rear chassis adjacent to an edge of the rear chassis, the vibration region being isolated from a remaining part of the rear chassis by a vibration blocking part so that vibration is not transmitted to the remaining part of the rear chassis; a vibrator disposed in the vibration region; a rear housing configured to surround the rear chassis and including a discharge port communicating with the vibration region of the rear chassis to discharge sound generated in the vibration region to an outside; and a waveguide disposed on the rear chassis and configured to guide sound generated in the vibration region to the discharge port of the rear housing.
