ABSTRACT:
An optical guide inserted between a liquid crystal display panel and a diffusion plate is formed by using a large number of optical fibers each obtained by coating a core with a cladding layer, and its exit surface is inclined with respect to an incident surface by a predetermined angle .theta.1. Accordingly, in assembly, it suffices to incorporate this optical guide, thus facilitating the assembling operation. In this case, image light emerging from the exit surface of the optical guide obliquely upward to the left is refracted by a refractor in a direction perpendicular to the exit surface of the refractor.
