Abstract:
Provided is a display apparatus which has a sufficient luminance even when viewed at a large viewing angle, and which can overcome a problem of color change. The display apparatus is a display apparatus including a display device showing a color change in accordance with viewer's viewing angle, and an anisotropic optical film having a diffusing property changed in accordance with the incident angle of light radiated thereinto. The anisotropic optical film has at least one scattering central axis, and an angle made between the scattering central axis and a direction along which the display device shows a minimum color change is from 20 to 65°, or −20 to −65°.
