摘要： A backlight unit is provided. The backlight unit includes a light guide panel (LGP); at least one point light source emitting light at an edge of the LGP; and a refraction member being positioned between the point light source and the LGP and refracting the light emitted from the point light source toward the optical axis of the point light source in order to reduce the azimuth angle of the light that is incident upon the LGP. The refraction member comprises a prism array in which a V-shaped prism pattern is repeatedly arrayed, the apex of the prism pattern facing the edge of the LGP. The refraction member further comprises a transparent portion that prevents the light from being totally reflected by the prism pattern in a region along an optical axis of the light source.

摘要： A backlight unit includes a point light source (120,220) emitting light and a light guide panel (110,210) including a holographic pattern (130,230) formed of shapes having a common center at the point light source. The shapes forming the holographic pattern (130) can be concentric circles. The shapes forming the holographic pattern (230) can be concentric polygons. Thus, since the incident azimuth angle of light incident on the holographic pattern can be made constant, an efficiency of light exhausted through the light exhaust surface can be improved. Also, since the distribution of the exhaust azimuth angle of the exhaust light can be made uniform, a uniform brightness can be obtained from the exhaust surface.
