Abstract
It is an object of the present invention to obtain high brightness and high color reproducibility in a liquid crystal display device. A liquid crystal display device 10 according to the present invention includes a liquid crystal panel 11 and a backlight unit 12. The liquid crystal panel 11 includes a pair of substrates 11a and 11b, and a liquid crystal layer 11c. The liquid crystal layer 11C includes liquid crystal between the substrates 11a and 11b. The liquid crystal is a substance having optical characteristics that vary with application of an electric field. The backlight unit 12 includes a light source. The back light unit 12 is configured to irradiate light onto the liquid crystal panel 11. At least one of the substrates 11a and 11b of the liquid crystal panel 11 includes a color filter 19 with a plurality of color sections R, G, B, and Y that exhibit the colors of blue, green, red, and yellow, respectively. The backlight unit 12 includes LEDs 24 as the light source. Each LED 24 includes an LED element as a light emitting source and a phosphor configured to emit light when excited by the light from the LED element. The phosphor includes at least two types of phosphors with different dominant emission wavelengths in a range of 480 nm to 580 nm.
