| titleOfInvention | Light filter |
| abstract | The invention provides an optical filter having a small incident angle dependency of light having a wavelength of 500nm or less and a high average transmittance in a visible light region. The optical filter has a light absorbing layer and a light reflecting layer, and satisfies the following requirements (i) and (ii). (i) In a spectral transmittance curve at an incident angle of 0 DEG, the average transmittance at a wavelength of 430nm to 620nm is 80% or more, the average transmittance at a wavelength of 430nm to 450nm is 76% or more, the average transmittance at a wavelength of 735nm to 1100nm is 5% or less, and the average transmittance at a wavelength of 350nm to 395nm is 5% or less. (ii) In the spectral transmittance curve at the incidence angle of 0 DEG, the light has a wavelength lambda of 50% transmittance in the wavelength region of 400nm to 425nm 0 (UV) having a wavelength lambda of 50% transmittance in a wavelength region of 400nm to 425nm in a spectral transmittance curve at an incident angle of 30 DEG 30 (UV) and the absolute value of the difference in the above wavelengths | λ 0 (UV)－λ 30 (UV) | is 5nm or less. |
