A liquid crystal display device includes: a liquid crystal display panel that includes red color filters, green color filters, and blue color filters; and an illumination device that illuminates the liquid crystal display panel with white light. The illumination device includes light-emitting elements that emit blue light, a green phosphor that absorbs a portion of the blue light emitted from the light-emitting elements and then emits green light, and a red phosphor that absorbs a portion of the blue light emitted from the light-emitting elements and then emits red light. The blue color filters are made of a colored material that contains a dye, and the chromaticity values x and y of the white light emitted from the illumination device satisfy the relationships 0.24<x and 0.24<y.
