摘要： A backlight includes light emitting diodes; a substrate on which light emitting diodes are mounted; and a reflection sheet. The surface on which the light emitting diodes are mounted of the substrate is opposed to a rear surface of the liquid crystal display panel. The liquid crystal display panel and the substrate each have a shape in which a common width in a first direction is longer than a width in a second direction, which is orthogonal to the first direction. The width of the substrate in the second direction is shorter than the width of the liquid crystal display panel in the second direction. The substrate is opposed to, while avoiding being opposed to both end portions of the liquid crystal display panel in the second direction, a central portion between the both end portions of the liquid crystal display panel.

摘要： A backlight unit has a light source area. The width of the light source area in a first direction is shorter than the width of a liquid crystal panel in the first direction. A plurality of LED modules (31) are arranged along the second direction perpendicular to the first direction. End lenses (41A, 41B) and a middle lens (42) for enlarging a light divergence angle are disposed on the plurality of LED modules (31). The direction in which the end lens (41A, 41B) enlarges the light divergence angle differs from that in which the middle lens (42) enlarges the divergence angle. This structure can reduce difference in brightness of the liquid crystal panel, while reducing the number of light sources.

摘要： In a liquid crystal display device including a liquid crystal display panel, and a backlight disposed on the rear surface of the liquid crystal display panel, the backlight is provided with a plurality of white light-emitting diodes arranged in a plane opposing the liquid crystal display panel. Based on a chromaticity coordinate value representing a color of emission identified for each of the white light-emitting diodes, the white light-emitting diodes are selectively combined for arrangement in proximity in such a manner that the color of emission as a result of averaging over the white light-emitting diodes (1a, 1b) to be arranged in proximity takes a predetermined value of chromaticity coordinates. Accordingly, the resulting liquid crystal display device can offer, although using the white light-emitting diodes having the problem of impairing the uniformity of the color of emission, higher-quality display images using a backlight with less non-uniformity of color and light emission as a whole, and prevents the increase of the manufacturing cost.
