Problems solved by technology

[0005] However, in order to improve the brightness and uniformity of the light emitted from the light guide plate, multiple optical films such as diffusion film, prismatic film, and protective film are used in the backlight assembly, which increases the manufacturing cost and the thickness of the product is relatively thick.

Abstract

A back light assembly and a liquid crystal display having the same manufactured at low price are provided to reduce manufacturing cost by reducing an optical sheet and improving luminance. A light source generates the light. A light guide plate(200) comprises the entrance face, lower-part and upper side. The entrance face receives the light from the light source. A lower part comprises a first prism pattern(250). First prism patterns are separated from each other. The first prism pattern comprises the first incline and the second incline. The first inclined plane is formed to be inclined from the plateau of the shear to the upper side direction. A reflective sheet(120) is arranged in the lower part of the light guide plate. One or more optical sheet(130) is arranged on the top of the light guide plate. The first inclined plane 35-50 inclines based on the normal of the upper side.

Description

technical field [0001] The invention relates to a backlight assembly, in particular to a backlight assembly which can improve brightness and reduce manufacturing cost. Background technique [0002] A liquid crystal display device is a flat panel display device that uses liquid crystals to display images. Compared with other display devices such as CRTs and PDPs, it has the advantages of thinner, lighter, lower driving voltage and less power consumption, and is widely used in the entire industry. [0003] The liquid crystal display panel in the liquid crystal display device that displays images is a non-light-emitting element that does not emit light itself. Therefore, it is necessary to provide a backlight assembly that provides light to the liquid crystal display panel. [0004] Generally, a backlight unit includes a lamp that emits light, a light guide plate (LGP) that guides light supplied from the lamp toward a liquid crystal display panel, and a reflective film disposed...
