PROBLEM TO BE SOLVED: To provide a manufacturing method of an optical alignment layer for a liquid crystal display element having excellent practicality, wherein time for optical alignment treatment is reduced, and to provide a manufacturing method of the liquid crystal display element using substrates provided with the alignment layer obtained by the manufacturing method. SOLUTION: In the manufacturing method of the optical alignment layer for the liquid crystal display element, an optical alignment layer containing a dichroic compound is formed on electrodes respectively provided on the substrates, the two substrates are opposed to each other at a fixed interval so that surfaces on which the optical alignment layer is formed are opposed to each other and the dichroic compound is aligned by irradiating surfaces of the substrates with non-polarized light from a direction oblique. In the manufacturing method of the liquid crystal display element, a liquid crystal material is injected into a gap between the two substrates provided with the optical alignment layer manufactured by the manufacturing method of the optical alignment layer for the liquid crystal display element, the liquid crystal material is sealed and then the liquid crystal material is aligned by heating the liquid crystal material up to a temperature at which the liquid crystal material shows isotropy.
