| description | To provide a light emitting device and a liquid crystal display device that are thin and high in luminance uniformity, and can obtain high luminance.SOLUTION: A light emitting device 10 has: a substrate 11; a plurality of light emitting elements 12 which are arranged discretely on one principal surface of the substrate 11; a reflection layer 13 which is arranged on the surface of the substrate 11 where the light emitting elements 12 are arranged; and a luminance uniformizing film 14 which is arranged on the surface side of the substrate 11 where the light emitting elements 12 are arranged, and transmits part of light of wavelength that the light emitting elements 12 emit and reflects part of it. A light emitting elements 12 have a 440-460 nm center value of light emission wavelength, and is 100 μm or less in thickness in a direction perpendicular to the principal surface of the substrate 11. The reflection layer 13 is either of a dielectric multilayer film and a cholesteric liquid crystal layer, and has a reflection factor of 45% or larger at a wavelength of 450 nm. The reflection layer 13 has a through hole 13a at the position of the light emitting element 12 when viewed from the direction perpendicular to the principal surface of the substrate. The reflection layer 13 is less thick than the light emitting element 12.SELECTED DRAWING: Figure 1
