The present invention provides an optical film having a liquid crystal layer having excellent durability, and a liquid crystal film. The optical film of the present invention has an organic base material and a liquid crystal layer disposed on the organic base material, the liquid crystal layer contains a photo-alignment compound, and in the liquid crystal layer, the photo-alignment compound is unevenly distributed on a side of the organic base material.

Optical film and liquid crystal film

An object of the present invention is to provide a polymer compound in which, by blending with a liquid crystal composition containing a liquid crystalline compound, alignment of the liquid crystalline compound in a phase difference layer to be obtained increases; and a liquid crystal composition, a phase difference layer, an optical film, a polarizing plate, and an image display device using the same. The polymer compound of the present invention is a polymer compound including a repeating unit represented by Formula (I), a repeating unit represented by Formula (II), a repeating unit represented by Formula (III), and a repeating unit represented by Formula (IV).

Two or more solutions comprising an organic pigment solution in which an organic pigment is dissolved in a good solvent, and a poor solvent compatible with the good solvent, or a solution of the poor solvent are allowed to flow through a microchannel in a non-laminar state; and organic pigment fine particles are deposited from the organic pigment solution in a course of flowing through the microchannel by changing the solubility of the organic pigment solution with the poor solvent or the solution of the poor solvent. As a result, nanometer-scale monodisperse organic pigment fine particles can be produced in a stable manner.
