Document Type and Number:
WIPO Patent Application WO/2023/287038
Kind Code:
A1
Abstract:
Disclosed are a light control barrier film, a wavelength converting film comprising same, and a display panel. The light control barrier film comprises: a base film composed of a plurality of nano-laminated films having different refractive indices; an organic planarizing layer located on at least one surface of the base film; a barrier layer located on one surface of the organic planarizing layer that does not face the base film; and an organic-inorganic adhesive layer located on one surface of the barrier layer that does not face the organic planarizing layer, wherein the organic-inorganic adhesive layer has a pencil hardness of HB or more, and the light control barrier film may satisfy both Equations 1 and 2 below: Average light transmittance at a light wavelength of 430 nm to 480 nm > 85% Average light transmittance at a light wavelength of 500 nm to 750 nm < 35%
