Abstract: The present invention provides an optical laminate which is suppressed in film thickness unevenness of an optically anisotropic layer and is free from point defects, a method of producing the same, and a polarizing plate and an organic EL display device using the optical laminate. The method of producing an optical laminate having an optically anisotropic layer A and an optically anisotropic layer B, includes where the layer A and the layer B are provided in direct contact with each other. The method further includes where both a composition a for forming the layer A and a composition b for forming the layer B contain a fluorine compound, and when the layer A is formed using composition a and layer B is formed using composition b, layer A and layer B are formed in this order under the condition that composition a and composition b satisfy predetermined surface tension relationships.
