Patent ID: 8305503

Claim:
A display device comprising: a display panel being driven according to an image signal; a backlight unit irradiating the display panel; and a phase difference element provided on a side opposite to the backlight unit with respect to the display panel, wherein the phase difference element includes: a base film having optical anisotropy, and a phase difference layer having optical anisotropy formed on the base film, wherein the phase difference layer has at least two kinds of phase difference regions with slow axes having different directions from each other, the at least two kinds of the phase difference regions are adjacently arranged in an in-plane direction of the base film, wherein the display panel has a first polarizer in a face on the phase different element side, and a second polarizer in a face opposite to the phase different element, and a slow axis of the base film faces in a direction parallel or vertical to a transmission axis of the first polarizer.
