Abstract
The invention discloses a liquid crystal display including in succession a first polarizer, a first glass layer, a liquid crystal, a second glass layer, a second polarizer, a purely reflective reflector, a light source and a reflector film surrounding the edge of the second glass layer while preserving at least one opening for letting light pass that is emitted by the source through the glass layer. Such an arrangement provides a liquid crystal display, which has an efficient and uniform irradiance without the aid of a light guide which renders the display lighter and flatter than the conventional displays.
