Title:
OPTICAL FILM LAYER AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/155281
Kind Code:
A1
Abstract:
Disclosed are an optical film layer (250) and a display device (10). The optical film layer (250) comprises an anisotropic optical layer with a single optical axis (251) and an isotropic optical layer (252), wherein multiple grooves are formed on one side of the anisotropic optical layer with a single optical axis (251); the isotropic optical layer (252) comprises a plate-shaped portion (2521), and multiple raised structures (2522) which are attached to one side of the plate-shaped portion (2521) and match the grooves in terms of shape and size; and the refraction index (ns2) of the isotropic optical layer (252) is greater than an extraordinary light refraction index (ne1) of the anisotropic optical layer (251) with a single optical axis.
