A light guide panel of a backlight unit and a backlight unit having the same are provided to increase a central luminance and accomplish uniformity by narrowing a reflection angle and maximizing reflection characteristics. A light guide panel(100) has a reflective surface(102) with an intaligo pattern formed such that a plurality of first V-shaped grooves(110) extend in the first direction and a plurality of second V-shaped grooves(120) extend in the second direction. The first and second V-shaped grooves(110,120) cross each other, and the depth of the first V-shaped grooves(110) is lower than the second V-shaped grooves(120). A plurality of third V-shaped grooves(130) formed on a light output surface(101) of the light guide panel(100) and extend in the third direction. The first V-shaped grooves(110) has a depth of 1/2 or 1/4 of the depth of the second V-shaped grooves(120). |
