    Abstract: An object is to provide an exposure method of a photoalignment layer in which an alignment pattern having no disorder can be formed. The exposure method of a photoalignment layer includes an exposure step of disposing an exposure mask and a substrate that includes a coating film including a compound having a photo-aligned group such that the exposure mask and the coating film face each other, irradiating the coating film with light to which the compound is photosensitive from the exposure mask side, and exposing the coating film to form an alignment pattern, in which the light is circularly polarized light having an ellipticity of 0.7 to 1.3, the exposure mask is a polarization diffraction element having an alignment pattern where a direction of an optical axis changes while continuously rotating in at least one in-plane direction, in the exposure step, the coating film is exposed to zero-order light and first-order light of the light diffracted by the exposure mask, and an intensity ratio of the zero-order light to the first-order light is 0.5 to 2.
