Abstract
A liquid crystal displaying device uses an inexpensive incandescent lamp or xenon lamp without sacrificing luminous intensity of a reflector, while maintaining an ease of installation. In the displaying device, a liquid crystal displaying panel, an incandescent lamp, a reflector, a lens and a heat-ray absorbing filter have a common optical axis and are secured to a bracket. The lamp is held by a socket and installed on the bracket transversely to the optical axis of the reflecting surface of the reflector. Further, the liquid crystal displaying panel has polarizing plates on both sides thereof. A coating to diffuse light from the lamp is disposed on one of the polarizing plates on the light incident side of the displaying panel. The polarizing direction of the polarizing plate on the other side of the displaying panel is selected so that the polarizing direction of the incident light waves on a reflective layer which is disposed on the front windshield glass provides a transversal or horizontal wave.
