The present invention discloses a flat panel display with sliding loudspeaker structure. The flat panel display comprises a display body, a sliding rail, and a sliding loudspeaker portion. The loudspeaker portion comprises a loudspeaker body, a sliding member and a connecting portion. By the matching structure of the sliding member and the sliding rail, the effect of allowing a user to freely adjust the loudspeaker body to different positions can be achieved. Besides, by further using the pivot of the loudspeaker body, the present invention allows the user to freely adjust the loudspeaker to different angular positions. Therefore, the problems of an immovably fixed loudspeaker position and angularly non-adjustable loudspeaker sound field on a conventional display are solved.
