Abstract: A display device includes a first light emitting component emitting light having a first wavelength in a wavelength range of blue light as a dominant wavelength, a second light emitting component emitting light having a second wavelength that is in the wavelength range of blue light as a dominant wavelength and longer than the first wavelength, first and second color filters that are disposed on a light exit side with respect to the first and second light emitting components and selectively transmit blue light in the wavelength range of blue light. The first color filter has a transmission spectrum in which a peak wavelength is a third wavelength in the wavelength range of blue light and the second color filter has a transmission spectrum in which a peak wavelength is a fourth wavelength in the wavelength range of blue light. The fourth wavelength is longer than the third wavelength.
