It is an object of the present invention to maintain high brightness of output light while ensuring sufficient color reproducibility in a liquid crystal display device. A liquid crystal display device 10 or 10′ according to the present invention includes a backlight device 12 or 40 and a liquid crystal panel 11. The backlight unit 12 or 40 includes LEDs 24 or 44 as light sources. The backlight unit 12 or 40 irradiates the liquid crystal panel 11 with light. The liquid crystal panel 11 includes a pair of substrates 11a and 11b, and a liquid crystal layer 11c. The CF substrate 11a of the liquid crystal panel 11 includes a color filter 19. The color filter 19 includes a plurality of the respective color sections R, G, B, and Y that exhibit the colors of red, green, blue, and yellow, respectively. The color filter 19 is configured such that the chromaticity of a blue color of output light obtained by passing light from the LEDs 24 or 44 through the color sections R, G, B, and Y in the color filter 19 lies outside a common region A3 of a NTSC chromaticity region A1 according to a NTSC standard and a EBU chromaticity region A2 according to a EBU standard in both a CIE1931 chromaticity diagram and a CIE1976 chromaticity diagram.
