摘要： It is the object of the present invention to provide a polarizing element capable of increasing a contrast ratio in an oblique direction and reducing a color shift in an oblique direction of a liquid crystal display apparatus. A polarizing element according to the present invention includes a polarizer, a negative C plate, a positive A plate, and a positive C plate each arranged on one side of the polarizer. The positive A plate is arranged between the polarizer and the positive C plate such that a slow axis of the positive A plate is substantially perpendicular to an absorption axis of the polarizer. The positive C plate has RthPC[590] of −60 nm or less.

摘要： An antiglare film and an antiglare sheet with which an image display apparatus excelling in contrast while maintaining excellent antiglare performance is obtained, and a simple process for producing them are provided. In the antiglare film of the present invention, a rugged shape in a first direction is substantially different from a rugged shape in a second direction perpendicular to the first direction. Preferably, an average gradient angle θa1 of the rugged shape in the first direction is larger than an average gradient angle θa2 of the rugged shape in the second direction. More preferably, a difference Δθa=θa1−θa2 between the average gradient angle θa1 and the average gradient angle θa2 is 0.5° to 30°.
