A display device includes: a color filter including a first transmissive filter, a second transmissive filter, and a third transmissive filter, the first, second and third transmissive filters being configured to transmit respective light beams having peak wavelengths different from each other; a first selective-wavelength-reflection layer adjacent to an optical-input surface of the first transmissive filter, the first selective-wavelength-reflection layer being configured to reflect light of a wavelength band that passes through the third transmissive filter; a second selective-wavelength-reflection layer adjacent to an optical-input surface of the second transmissive filter, the second selective-wavelength-reflection layer being configured to reflect light of a wavelength band that passes through the third transmissive filter, the second selective-wavelength-reflection layer being identical in composition to the first selective-wavelength-reflection layer; and a light emitter configured to emit light that travels toward the color filter.
