Light guide plate and two -sided display panel

The utility model provides a light guide plate and two -sided display panel, light guide plate include the light guide plate body, the upper surface of light guide plate body and lower surface be all as going out a plain noodles, and the lateral wall is as going into the plain noodles, light from the lateral wall gets into the light guide plate this internal and from upper surface and lower surface jet out be formed with on the upper surface of light guide plate body or the lower surface and be used for the partly light of reflection and see through partly reflection of light layer, make there is the luminance difference between the upper surface of light guide plate body and the luminance that the lower surface jetted out. The utility model provides a light guide plate and two -sided display panel not only can improve the utilization ratio of light, reduces the energy consumption, but also the optics diaphragm that a display screen that may not need luminance to have relatively high expectations corresponds adopts the higher optics diaphragm of gain to can reduce cost.
