Abstract

PURPOSE:To obtain the effect of uniform visibility, a wide angle of field, and high contrast, by providing a light diffusion element on the side opposite to an irradiating device for parallel light with a liquid crystal panel in-between. CONSTITUTION:The incident angle of the parallel rays incident to a transmission type liquid crystal panel 2 from an irradiating device 1 for parallel light is in the direction where the contrast of the transmitted light is maximized in the panel 2. With the liquid crystal display of such constitution, the parallel rays or nearly parallel rays are made incident to the panel 2 so as to transmit therethrough in the direction where the max. contrast is obtained; therefore, the display of high contrast is inevitably obtained, and further the parallel rays transmitted through the panel 2 are refracted by a concave lens 3 and are diffused as if the rays are radiated from the focus of said lens 3, so that the observers 5a, 5b in the different observation directions are able to observe the same display with the same visibility.
