Abstract

The present invention provides a light polarization film capable of suppressing a decrease in light emission efficiency even when the film is continuously irradiated with light and suppressing a change in degree of polarization even under a wet heat environment, a method for manufacturing the same, a laminate, and a method for manufacturing the same. The light polarization film of the present invention includes a polymer, and quantum rods, in which the quantum rods are aligned such that a major axis of each of the quantum rods is parallel to one direction parallel to a surface of the light polarization film, a moisture content is 1.0% or less, and an oxygen permeability coefficient is 200 cc·20 μm/m·day·atm or less.
