[Problem to be Solved] Provided are: a polarizing plate and an image display apparatus, in which bright-place contrast can be improved; and a method for improving visibility. [Solution] According to one embodiment of the present invention, there is provided a polarizing plate 10 including: a polarizer 11; and a light transmissive film 12 with a birefringent property in a plane, disposed on one surface of the polarizer 11, wherein the light transmissive film 12 satisfies a relationship of the following expression (1):
where a refractive index in a slow-axis direction which is a direction with a greatest refractive index in a plane of the light transmissive film 12 is n x , a refractive index in a fast-axis direction which is a direction orthogonal to the slow-axis direction in the plane is n y , and an average refractive index of the light transmissive film 12 is N; and wherein the polarizer 11 and the light transmissive film 12 are placed so that both fast-axis direction of the light transmissive film and absorption-axis direction of the polarizer 11 are along a horizontal direction. |
