OPTICAL FILM COMPRISING LUMINESCENT MATERIAL AND OPTICAL DISPLAY APPARATUS COMPRISING THE SAME

摘要

PURPOSE: An optical film including luminescent materials and an optical display apparatus including the same are provided to obtain a high refractive index and brightness and to minimize a failure rate caused by foreign materials by preventing scratches. CONSTITUTION: An optical film(100) comprises a base film(110) and an optical functional layer(120). One of the base film and the optical functional layer includes luminescent materials. The base film includes a resin film made of transparent materials. The luminescent materials include one or more fluorescent materials or phosphors. The absorption wavelength of the luminescent material is 240 to 380 nm or 420 to 380 nm, and an emission wavelength is 520 to 580 nm. The optical functional layer is formed on the base film, concentrates, diffuses, penetrates, refracts, or reflects the light and includes an optical pattern.
