Abstract
A display device capable of emitting sufficient fluorescence is provided without an increase in the thickness of the liquid crystal layer. The device includes: a fluorescent emission layer () having fluorescent pigment molecules that absorb light to emit fluorescence; and a liquid crystal layer () capable of switching between a transparent state and a scattering state. The fluorescent pigment molecules are dichroic fluorescent pigment molecules () with different emission intensities depending on the direction of emission. The dichroic fluorescent pigment molecules () in the fluorescent emission layer () are oriented so as to have transition dipole moments with the same direction.
