A backlight includes a light source in which blue LEDs are planarly arranged in a matrix with a first interval, and a color conversion sheet disposed covering the light source. First red quantum dots that receive blue light and emit red light, and first green quantum dots that receive blue light and emit green light are dispersed in the color conversion sheet. An RG quantum dot layer, in which second red quantum dots that receive blue light and emit red light and second green quantum dots that receive blue light and emit green light are dispersed, is disposed around each of the blue LEDs in planar view.
