An all-in-one light guide plate, a backlight apparatus employing the same,
and a method of manufacturing the all-in-one light guide plate are
provided. The all-in-one light guide plate has a structure in which a
plurality of protrusion type refractive elements for outputting light are
integrated into the light guide member. It is possible to improve optical
properties by more densely arranging the refractive elements with
distance from the light source.
