Abstract:
A light absorbing member includes a first dichroic dye and a second dichroic dye. The first dichroic dye has an absorption peak wavelength between a first emission peak wavelength of the first light-emitting layer and a second emission peak wavelength of a second light-emitting layer. The second dichroic dye has an absorption peak wavelength between the second emission peak wavelength of the second light-emitting layer and a third emission peak wavelength of the third light-emitting layer. An angle of a molecule of the first dichroic dye in an absorption axis and an angle of a molecule of the second dichroic dye in an absorption axis with respect to a normal direction of the reflective layer are from 70 degrees to 90 degrees.
