Abstract
The polarizing plate of the present invention includes a polarizer and an optical element that rotates a polarization plane of polarized light emitted from the polarizer, an orientation direction on a surface of the optical element on a polarizer side is parallel to an absorption axis of the polarizer, an orientation direction on a surface of the optical element opposite to the polarizer is perpendicular to the absorption axis of the polarizer, and Δnd and a birefringence parameter Rof the optical element fall in a range of a predetermined region in an orthogonal coordinate in which Δnd is indicated along a vertical axis and the birefringence parameter Ris indicated along a lateral axis.
