1. A liquid crystal display device including an under light type back light unit in which light emitted from a plurality of linear light sources is reflected by a reflecting sheet disposed at a rear side of the plurality of linear light sources, then transmitted through a light modulation film and a light diffusion plate to form a planar light source with a first uniform luminance indirectly irradiating a first portion of a liquid crystal panel from a rear side thereof,wherein one end portion of the light modulation film is shielded by a light shielding plate, and light emitted from one of the plurality of linear light sources is shielded by the light shielding plate and transmitted through only the light diffusion plate to irradiate a second portion of the liquid crystal panel from the rear side thereof with a second luminance higher than the first luminance.
