A rotor of an AC generator includes a field coil, a pole core having a plurality of claw poles disposed in the circumferential direction to enclose the field coil to provide a plurality of magnetic fields when the field coil is energized and a cylindrical permanent magnet disposed inside the plurality of claw poles to supplement the plurality of magnetic fields. This uncured cholesteric liquid crystal layer 18 is cured by applying to it ultraviolet light with a low intensity under such conditions that one surface of the uncured cholesteric liquid crystal layer is brought into close contact with the alignment film 16 on the glass substrate 12 so that it will not come into contact with oxygen and that the other surface of the same is exposed to air. The top case may include a coupling portion formed in a lateral surface thereof to be coupled to the lateral surface of the display module and an edge portion of the back cover.
