PROBLEM TO BE SOLVED: To provide a display device in which display with high contrast can be obtained.SOLUTION: The display device includes: a light source; a liquid crystal element that controls the polarization state of light emitting from the light source; a phosphor that absorbs the light transmitted through the liquid crystal element and emits fluorescent light in a wavelength region different from a wavelength region of the original light; a pair of polarizing plates disposed at an incident side and an exiting side of the liquid crystal element; and a band-pass filter disposed between the light source and the phosphor. The pair of polarizing plates, when arranged in a cross-Nicol condition, has an absorption band including the maximum absorption wavelength in the wavelength region of the light. The band-pass filter has a non-transmission band of light out of the absorption band. |
