POLARIZING ELEMENT FORMED BY STACKING FILM HAVING HIGH RETARDATION AND LAYER CONTAINING DICHROIC DYE, AND DISPLAY DEVICE PROVIDED WITH SAME

摘要

The purpose of the present invention is to provide a polarizing element that can be easily manufactured and has excellent polarization performance, and a display device that is provided with the polarizing element. A polarizing element of the present invention is characterized in that a stretched film having a retardation of 3000-50000 nm and a layer containing at least one type of dichroic dye are stacked therein and in that the thickness of the stretched film is 20-500 μm. This polarizing element employing this specific stretched film exhibits a high degree of polarization, specifically, a degree of polarization of 85% or higher, and exhibits high dichroism, specifically, dichroism of five or higher.
