The utility model discloses a side light type glass board that is shaded this, it includes glass substrate, glass substrate has light source incident surface, reflection of light face and light source output face, and wherein, only the light source incident surface is the transparent surface, and reflection of light face and light source output face are anti -dazzle face, are provided with transparent reflection of light dot matrix on the reflection of light face. The utility model discloses being shaded from the sun the board with monolithic glass and having replaced the backlight unit who comprises multiple optical element, it is low to have reduced the transmissivity that the multilayer coating materials led to the fact, problem that the optical loss is big, the attenuate thickness, lightened weight, reduced power consumption, luminance has improved, more high temperature resistant than acryl light guide plate, be difficult to the deformation to can use as LCD's back shroud.
