Abstract
A liquid crystal display device contains a liquid crystal panel and a light transmission member disposed below the liquid crystal panel. A reflection sheet is disposed below the light transmission member and a light source is disposed adjacent to one end of the light transmission member. A reflector encases the light source. The periphery of the reflector has reflection walls and forms an opening continuous with the reflection walls. Light direction control walls are formed near the opening of the reflector to control the direction of the light from the light source. The light direction control walls cut off light directed in directions other than a predetermined set of directions. An inner surface of the light direction control walls is composed of reflection layers formed from a different material from the material that forms the reflection walls.
