Abstract
An optical sheet and a display optical filter which can increase a contrast ratio in a bright room are provided. The optical sheet for the display optical filter includes a transparent substrate including a plurality of pattern grooves formed thereon; and a light shielding pattern formed of a light absorbent material filled in the plurality of pattern grooves. The light shielding pattern may be formed of a material for either absorbing or shielding light filled in the plurality of pattern grooves. In particular, when an external illuminance increases from 0 Lux to 250 Lux, a reduction rate of a color gamut in CIE color coordinates may be 9% or less with respect to NTSC, and the reduction rate of the color gamut is relatively less in comparison with the case where the optical sheet of the present invention is not used.
