PURPOSE: A LCD structure is provided to improve brightness by using a lenticle screen instead of a conventional first polarizing plate and a prism sheet. CONSTITUTION: A backlight unit includes a light guide plate and a prism sheet. A lenticular screen(300) has waves in the upper and the lower direction. Convex portions(301~30n) are consecutively formed in the upper surface of the glass substrate in the lenticular screen. The convex portions form a convex lens shape.
