OPTICAL FILM AND DISPLAY FILTER COMPRISING THE SAME

摘要

PURPOSE: An optical film and a display filter including the same are provided to prevent brilliant by having a reflection-preventing function and a near infrared ray absorption function in one film. CONSTITUTION: A base film(10) is a transparent polymer. Visible ray electric light transmittance of a first pigment is greater than or equal to 82%. Near-infrared ray region transmittance of the first pigment is less than or equal to 20%. A near-infrared ray absorbing layer(20) comprises the first pigment and a second pigment. The second pigment has an absorbing function in a wavelength area of 380-780nm. The weight ratio of the first pigment and the second pigment is 1:0.0001-0.5. A reflection-preventing layer is formed at the other side of the base film.
