Abstract
Abstract A liquid crystal display including many speakers within a stand and having a display unit, a display angle of which can be adjusted by a cam in order that a user can conveniently see it. The stand supports the display unit through a support and has an inclined part between a front part and a rear part. In addition, a speaker for outputting a high-pitched sound is installed within the front part of the stand and speakers for outputting a middle-low pitched sound are installed within the both sides of the stand. The support is rotatably connected to the display unit and the stand by a driving of the cam and contacted with the cam provided to toe inclined part of the stand and the angle of the support is adjusted by a rotation of the cam and so an angle of the display unit is adjusted.
