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.
Claims7
A display comprising:
- a first substrate and a second substrate;
- a liquid crystal sandwiched between said first substrate and said second substrate;
- a reflective film having at least one opening, said reflective film covering side edges of said first substrate, and said at least one opening providing an at least exposed portion of said side edges;
- and
- at least one light source located within said at least one opening to provide light through said a least exposed portion.
An electronic apparatus having a display, said display comprising:
- a first substrate and a second substrate;
- a liquid crystal sandwiched between said first substrate and said second substrate;
- a reflective film having at least one opening, said reflective film covering side edges of said first substrate and said at least one opening providing an at least exposed portion of said side edges;
- and
- at least one light source which provides light through said at least exposed portion.
