Method of producing elliptically polarizing plate and image display using the ellipticallly polarizing plate

摘要

The present invention provides: a method of producing a broadband and wide viewing angle elliptically polarizing plate having excellent characteristics in an oblique direction as well; and an image display using the elliptically polarizing plate obtained through the method. The method of producing an elliptically polarizing plate according to the present invention includes the steps of: subjecting a surface of a transparent protective film to alignment treatment; forming a first birefringent layer by applying a liquid crystal composition onto the surface of the transparent protective film subjected to the alignment treatment; laminating a polarizer on a surface of the transparent protective film opposite to the surface subjected to the alignment treatment; and forming a second birefringent layer by laminating a polymer film on a surface of the first birefringent layer, in which the elliptically polarizing plate has a relationship represented by the following expression (1) 2± + 40° < ² < 2± + 50° in the expression (1), ± represents an angle between an absorption axis of the polarizer and an alignment direction of the transparent protective film, and ² represents an angle between the absorption axis of the polarizer and a slow axis of the second birefringent layer.
