LIGHT GUIDE PLATE, AND BACKLIGHT UNIT AND DISPLAY DEVICE INCLUDING THE SAME
First Claim
1. A backlight unit comprising:
- a light source which generates light used by a display panel of a display device to display an image; and
a light guide plate which receives the light from the light source and emits the light toward the display panel of the display device,wherein the light guide plate comprises;
a light emission surface through which the emitted light exits from the light guide plate toward the display panel of the display device;
a base layer;
a light transmitting layer on the base layer, the light transmitting layer defining the light emission surface of the light guide plate; and
a light transmitting particle provided in plurality between the base layer and the light transmitting layer, the light transmitting particles contacting the base layer,wherein the light transmitting particle has a refractive index higher than a refractive index of the light transmitting layer.

Abstract
A backlight unit and a display device includes a light source which generates light used by a display panel to display an image; and a light guide plate which receives the light from the light source and emits the light through a light emission surface thereof. The light guide plate includes: a base layer; a light transmitting layer on the base layer and defining the light emission surface of the light guide plate; and a light transmitting particle provided in plurality between the base layer and the light transmitting layer. The light transmitting particle has a refractive index higher than a refractive index of the light transmitting layer.
