A liquid crystal display device is provided to properly form the first optical pattern and the second optical pattern, thereby improving brightness uniformity without loss of a viewing angle. A plurality of lamps(120) is installed in a lower side of an LCD(Liquid Crystal Display) panel(150) in predetermined array. An optical member(135) is arranged between the liquid crystal panel and lamps. The optical member comprises the first optical pattern(135b) and the second optical pattern(135c) of a convex shape. The first optical pattern is formed in predetermined array. The first optical pattern disperses light provided from the lamp. The second optical pattern is formed in a non-linear type between the first and second optical patterns. The second optical pattern concentrates light from the lamp. |
