Abstract
A liquid crystal display unit (20) includes a main housing (21), a mirror housing (22) and a sub housing (23) which are successively connected with each other in a rotatable manner. The main housing (21) is provided on both sides with a pair of rearwardly extending arms (24 and 25), so that engaging projections (27) of the sub housing (23) are slidably engaged with sliding guide grooves (28) of the arms (24 and 25). Thus, the display unit (20) can be selectively brought into a folded condition in which the mirror housing (22) and the sub housing (23) are superposed along the arms (24 and 25) with the engaging projections (27) slid frontwardly and an opened condition in which the mirror housing (22) is downwardly inclined and the sub housing (23) is opened from the mirror housing (22). The sub housing (23) is provided with a liquid crystal display panel (38) adapted for transmission of light. In the opened condition, the light (D) transmitted from above through the liquid crystal display panel (38) is reflected forward by a mirror (31) provided on the mirror housing (22) for observation by a user holding the unit (20) with the upper surface of the panel upward and the surface of the…
