Disclosed are a light guiding plate having a slimmed thickness and small volume, a manufacturing method of the light guiding plate and a liquid crystal display (LCD) having the light guiding plate. The light guiding plate has a light reflection face with at least one brightness enhancement recess, which allows a light having an optical distribution of a planar light source to be supplied toward the LCD panel. A brightness concentration recess is formed in the light output face to concentrate the brightness. The brightness enhancement recess and the brightness concentration recess allow an enhancement in the brightness and an increase in the uniformity in the brightness. The light guiding plate excludes use of the diffusion sheet, the prism sheet and the reflection plate from a backlight assembly, thereby significantly decreasing the total weight and volume of the LCD.
