A large number of liquid crystal display devices is formed on a single plane, each of the liquid crystal display devices being formed by arranging liquid crystal between transparent substrates which allow light from a light source to pass through. Display portions of the respective liquid crystal display devices are covered by a masking member (23) and a light guide which is formed of light guide devices, one or more of which being provided for each of said liquid crystal display devices, and junctions between the liquid crystal display devices are also covered by the light guide. With this structure, when the light guides are formed such that the junctions between the plurality of liquid crystal display devices are also covered, lattice-like non-display lines do not appear, thereby providing substantially visually uniform brightness throughout the entire screen of the large-sized liquid crystal display and improving the entire image.
