Provided is a display device including: a light guide member for mixing light from a blue LED element coated with a translucent resin mixed with phosphor particles which converts blue light into green light with light from a red LED element to make white light exit from a light exit surface; and a non-self light emission display element provided on an irradiating surface side of the light guide member. Therefore, the display element is irradiated with white light whose sufficient wavelength region is 600 nm or more and whose intensity efficiency is high. When the display device further includes a circuit for separately controlling light emission intensities of the red LED element and a blue LED element, chromatic balance can be adjusted even after manufacturing and an intensity of the display device and color reproducibility thereof can be easily set in an optimum range even after assembly.
