ABSTRACT:
A light emitting layer produces light having peak intensities in a wavelength range of not less than 460 nm and not more than 510 nm and a wavelength range of not less than 550 nm and not more than 640 nm, respectively. Each of a red color filter layer, green color filter layer, and blue color filter layer has a transmittance of 50% or more in a prescribed wavelength range and a transmittance of 10% or less in a prescribed wavelength range. The ratio of an intensity value of the light emitted from the light emitting layer at a wavelength of 575 nm to an intensity value of the light emitted at a wavelength of 475 nm is not less than 0.4 and not more than 4.0.
