WAVELENGTH SELECTION FILTER, METHOD OF MANUFACTURING WAVELENGTH SELECTION FILTER, AND DISPLAY DEVICE

摘要

Provided is a wavelength selection filter, wherein the thickness of a first high refractive index part is T1, the thickness of a second high refractive index part is T2, the refractive index of the material of a high refractive index layer is n1, the refractive index of the material of an uneven structure layer is n2, the refractive index of the material of an embedded layer is n3, the area ratio of the first high refractive index part is R1, and the area ratio of the second high refractive index part is R2. n1n2, n1n3, and R1+R21. The value of T1×{n1×R1+n2×(1-R1)} is a first parameter, the value of T2×{n1×R2+n3×(1-R2)} is a second parameter, and the ratio of the second parameter to the first parameter is 0.7-1.3.
