ABSTRACT:
An electronic apparatus with a liquid crystal display (LCD) such as a folding cellular phone, by which display contents on the LCD is viewable even when the apparatus is closed, and thus improving the visibility of the LCD. The folding electronic apparatus comprises a display unit housing and an operation unit housing, which are connected by a hinge in a manner permitting a turning movement of each housing. The display unit housing is fitted with a transmissive LCD, both sides of which are viewable, and the operation unit housing has input keys. The apparatus further comprises a display control means for controlling the LCD to display reversed display contents if necessary depending on whether a user views the front side of the LCD or its backside. One side of the operation unit housing, which is in face-to-face contact with the LCD when the apparatus is folded, is reflectorized for reflecting the light to the LCD. Besides, a light source, which is disposed inside the operation unit housing for lighting the input keys, can also illuminate the LCD when the apparatus is folded.
