Document Type and Number:
WIPO Patent Application WO/2022/145824
Kind Code:
A1
Abstract:
An embodiment of the present invention provides an optical film having an optical transmittance change (ΔTT) of 0% (exclusive) to 0.5% (inclusive) as measured for a thickness of 50㎛ before and after heat treatment at 150℃ for 30 minutes and exposure to visible light for 150 hours. The optical film may have a slope of optical transmittance of 1.65 [%/nm] or higher in the wavelength region of 370 nm to 430 nm on the basis of a thickness of 50㎛. In addition, an embodiment of the present invention provides a display device including the optical film.
