Patent ID: 8358388

Claim:
A display device comprising: a planar light source including a plurality of light-emitting elements; and a display panel, wherein the planar light source illuminates the display panel, each of the plurality of light-emitting elements is comprised of a combination of a semiconductor light-emitting element for emitting primary light and fluorescent substances for absorbing the primary light and emitting secondary light having a longer wavelength than the primary light, and each of the plurality of light-emitting elements emits combination light of the primary light and the secondary light, the plurality of light-emitting elements are divided into at least a first chromaticity group having chromaticity close to central chromaticity (x+Δx, y+Δy) and a second chromaticity group having chromaticity close to central chromaticity (x−Δx, y−Δy), the light-emitting elements belonging to the first chromaticity group and the light-emitting elements belonging to the second chromaticity group are alternately provided in at least a partial area of the planar light source, in a longitudinal direction and a transverse direction, respectively, and chromaticity of the planar light source ranges from (x−A·Δx, y−A·Δy) to (x+A·Δx, y+A·Δy) where A is chromaticity unevenness and is 20% or lower.
