Abstract

PURPOSE:To form a bright image even with a small aperture part by providing a couple of lenticular lenses or compound lenses at both sides of a liquid-crystal layer corresponding to positions of picture elements, and making the focal points of the couple of the lenses coincident with each other. CONSTITUTION:Liquid crystal 20 which has picture element electrodes 16 and opaque parts 18 on one surfaceis clamped between substrates 10. Polarizing plates 30 and 30 are laminated outside of them and numbers of lenticular lenses (or compound lens) 40 and 40' having optical axes in parallel are provided further outside. The focal point F1 of the lens 40 and the focal point F2 of the lens 40' are at the same position and parallel input light beams L1 appear at an output side through the picture element electrodes 16. Namely, the parallel incident light L1 is emitted as parallel light beam L1 without being cut off by the opaque parts 18. A light beams which is made incident slantingly is also passed through a picture-element electrode 16 similarly. Consequently, a bright image is formed even with a small aperture part and the visual field is widened, so that this device is used suitably for a large-size projector.
