a rotating apparatus for a liquid crystal display comprises : a main body provided with a mounting recess having a predetermined radius of curvature ; a liquid crystal display provided , at its bottom surface , with a curved portion corresponding to the mounting recess so that the curved portion rotates in surface contact with the surface of the mounting recess ; and an angle regulator for guiding the rotation , in a predetermined direction , of the lcd and setting a position of the lcd when rotated to a predetermined position . the angle regulator includes : a plurality of bosses protruding from the bottom surface of the lcd ; guide holes formed along a curvature of the mounting recess so as to form passageways through which the bosses are rotated ; guide rails protruding from both sides of the guide holes toward the bottom surface of the mounting recess ; and sliders which slide along the guide rails and engage the bosses .
