Abstract

The invention provides a patterned polarization plate that contributes to reduction of crosstalk. The invention is a patterned polarization plate disposed on an observation-side surface of a display panel, having at least a patterned phase difference layer in which at least one of slow axes and retardation are mutually different and stripe-shaped first and second phase difference patterns are mutually disposed, a patterned phase difference film having a film that supports the patterned phase difference layer, and a polarization film, in which a pattern cycle direction in the patterned phase difference layer and absorption axes in the polarization film are in parallel with each other, and the polarization film is a patterned polarization plate having the absorption axes disposed in parallel with the up and down directions of a display surface of the display panel.
