ABSTRACT:
A liquid crystal display apparatus comprises a first and second housing portions. The first and second housing portions are coupled so that the angle of the opposing surfaces may be adjustable. A light transmitting portion is formed on the upper surface of the first housing portion. The light beam received by the light transmitting portion is further transmitted through a liquid crystal plate and a colored filter housed in the first housing portion and then is led to impinge upon the mirror provided on the second housing portion. An image formed on the liquid crystal plate can be observed as a multicolored image through a light beam reflected from the mirror.
