(57) [Summary] [Problem] To provide high contrast, good viewing angle characteristics, Another object is to provide an elliptically polarizing plate used in a field-effect liquid crystal display device having excellent display uniformity. An elliptically polarizing plate disposed so as to sandwich a liquid crystal layer of a liquid crystal display device, wherein the elliptically polarizing plate for absorbing polarized light in a specific direction is tightly laminated with a transparent protective film in a sandwich form, and the protective film is provided. Has birefringence, its slow axis crosses the absorption axis of the elliptically polarizing plate, and its phase difference is 0.005 to 0.25 μm. Polarizer. |
