Abstract:
In front of a liquid crystal display element, a surface light source is arranged which emits a light toward the liquid crystal display element and lets lights coming from its front and its back permeate therethrough. The liquid crystal display element has reflection/permeation means which is provided behind a liquid crystal cell and a liquid crystal layer, and which reflects a part of a light that comes to each of a plurality of pixels from the front of the liquid crystal cell, and lets the other part of the light permeate the reflection/permeation means.
