An optical sheet of the present invention includes a specific wavelength absorption layer that contains a polycarbonate as a main material and a light absorbing agent that absorbs light of a specific wavelength out of light in a wavelength range of 350 nm to 740 nm, in which the polycarbonate has a viscosity average molecular weight Mv of 20,000 to 30,000. In addition, the specific wavelength absorption layer further includes an ultraviolet absorbing agent that absorbs light in a wavelength range of 100 nm to 420 nm.

Optical sheet and optical component

An optical sheet of the present invention is an optical sheet that has flexibility and is used in a curved state of being curved in one direction, and includes a polarized layerthat polarizes incident light and a specific wavelength absorption layer provided on a curved concave side from the polarized layerand containing a resin material and a light absorbing agent that absorbs light in a specific wavelength range out of light in a wavelength range of 350 nm to 740 nm. In addition, the resin material is preferably a polycarbonate having a viscosity average molecular weight Mv of 20,000 to 30,000.
