Light guide plate and display device
A display device includes a light guide plate. A light incident on the light guide plate from a linear light source is reflected by a reflecting surface of each of prisms and emitted from a lower surface of the light guide plate. The emitted light is irradiated onto a liquid crystal panel, reflected by a reflecting layer provided within the liquid crystal panel and advances toward a front direction of a screen. Herein, the light guide plate has on its lower surface as an emission surface a number of minute protrusions each having a shape of triangle in vertical cross-section in a manner that the protrusions cover with no space therebetween a whole effective area of the lower surface, and thereby to obtain an antireflection effect.
