Title: Backlight, liquid crystal display device and electronic equipment
Inventor: BABA MASATAKE
IPC: F21V8/00
Filed: 2001-02-15
Abstract: PROBLEM TO BE SOLVED: To realize a display of a liquid crystal panel by the use of a surrounding light even when a light source is off and to achieve high luminance at the same time. SOLUTION: As light emitted from a light irradiation face 15 after being reflected mainly at a reflective face of a prism face is not diffused uselessly and has relatively strong directivity, it is not necessary to arrange multiple prism sheets between a light guide panel and a liquid crystal panel for convergence. Due to this arrangement, light coming from the liquid crystal panel, ambient light for example, reaches a light guide panel 3 without large attenuation, even if it is weak. If, further, ambient light, for example, enters a backlight 1 from the liquid crystal side, it mainly reaches a transmission face of a prism face 14 of the light guide panel 3.  Then, the light reaches a reflective sheet 4 to be reflected by it and returns to the light irradiation face 15 whether after passing through the transmission face or being reflected by it, and is irradiated on the liquid crystal panel to be used for illumination.
