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.
