1. A laminate comprising:
a pair of polarizers including a first polarizer and a second polarizer transmission axes of which are parallel to each other;
a retarder between the pair of polarizers;
a diffusion layer directly on a side without the retarder of the first polarizer; and
a viewing angle compensation film directly on a side of the second polarizer opposite the retarder, wherein
the retarder includes an in-plane slow axis that forms an angle of 40° or greater and 50° or smaller with the transmission axis of the first polarizer.
