Abstract: A phase difference plate and a liquid-crystal layer are provided between a polarizing plate and a selective reflection layer formed of cholesteric liquid crystal. A first color filter layer is provided on the polarizing plate side of the selective reflection layer. On the back side of the selective reflection layer, a second color filter layer is arranged. On the back side of the second color filter layer, a backlight is provided. When a liquid-crystal display device functions as a reflective liquid-crystal display device, light entering through the polarizing plate is reflected totally by the selective reflection layer and passes through the first color filter layer twice. When the liquid-crystal display device functions as a transmission liquid-crystal display device, light from the backlight passes through the selective reflection layer. Then, the light passes through the second and first color filter layers once and is outputted.

The light guide has a light emitting surface and a reflecting surface in addition to a light incident face placed near the tubular light source to receive light emitted from the tubular light source. The light guide has a plurality of projections or grooves arrayed on the light emitting surface to extend parallel to each other along a longitudinal direction of the tubular light source so as to cause the light incident from the light incident face to emerge from the light emitting surface. The height or depth of each of the projections or grooves increases from the central portion to the two end portions in the longitudinal direction of the tubular light source.

Abstract: On a light exit surface which is the first principal plane of a light guide, multiple projections are fabricated in specific rows. These projections have light exit surfaces and continuous multiple slopes, and are fabricated from optically identical materials having the same refractive index as the substrate of the light guide. The slope farthest from the light entry edge surface is formed as a light exit surface, i.e., a surface which breaks the conditions for the total reflection of the incident light. On the other hand, the slope nearest the light entry edge surface which is the total reflection surface is formed such that the incident light is totally reflected.
