Abstract:
There is provided an optical member that can realize a liquid crystal display apparatus that is excellent in mechanical strength and has high illuminance. An optical member according to an embodiment of the present invention includes a polarizing plate, a reflective polarizer, and a prism sheet in the stated order. The optical member has a reflectance of 70% or more for linearly polarized light having a wavelength of 650 nm entering the reflective polarizer at 45°.
