OPTICAL SHEET AND DISPLAY OPCTICAL FILTER

摘要

An optical sheet and a display optical filter are provided to improve a light room contrast ratio and definition by reducing diffused reflection of light emitted from a display. An optical sheet includes a transparent film(110), optical absorption patterns(120), and a fluent adhesion layer(130). The optical absorption patterns are formed on one surface of the transparent film. The fluent adhesion layer is formed on the one surface of the transparent film on which the optical absorption patterns are formed. The fluent adhesion layer is formed by coating a fluent adhesive on the transparent film and includes an absorption pigment with the maximum absorption wavelength in a range of 580 to 600nm.
