Phase difference element and display unit

摘要

A phase difference element capable of decreasing deterioration of 3D characteristics and a display unit including the phase difference element are provided. The phase difference element includes a phase difference film, and an anti-glare film. The phase difference film has a phase difference layer composed of two or more phase difference regions each having different direction of a slow axis that are regularly arranged in a plane. Retardation of the anti-glare film is 20 nm or less and total haze of the anti-glare film is 30% or less.

1. A phase difference element comprising:
an anti-glare film; an alignment film; and a phase difference film provided between the anti-glare film and the alignment film, wherein the phase difference film has a phase difference layer composed of two or more phase difference regions each having different direction of a slow axis that are regularly arranged in a plane, wherein retardation of the anti-glare film is 20 nm or less and total haze of the anti-glare film is 30% or less, wherein crosstalk of light transmitted through a first one the phase difference regions and crosstalk of light transmitted through a second one of the phase difference regions is 3.5% or less, wherein the alignment film includes two or more alignment regions, each region having different alignment directions, and wherein a first alignment region includes grooves extending in a first direction, and a second alignment region includes grooves extending in a second direction that is orthogonal to the first direction.
