Abstract: To obtain a liquid crystal element having a plurality of alignment domains with a simple configuration. A manufacturing method of a liquid crystal element including: a first process that forms a first substrate having a first alignment film subjected to uniaxial alignment treatment; a second process that forms a second substrate having a second alignment film subjected to uniaxial alignment treatment; a third process that forms a liquid crystal layer between the first alignment film and the second alignment film using a liquid crystal material including a monomer which can be polymerized by light irradiation; and, of a first region and a second region adjacent to each other in the liquid crystal layer in a plane view, a fourth process that performs light irradiation with no voltage applied or with a voltage less than a threshold value applied to the first region.

Abstract: To provide a liquid crystal element having multiple alignment domains with a simple configuration. The liquid crystal element includes: a first and a second substrate; a liquid crystal layer inbetween the two substrates; and a seal material with an injection port; where a first and a second alignment film each has an alignment regulating force in one direction on a surface in contact with the liquid crystal layer, a polymerized monomer is present at the interface between each of the two alignment films and the liquid crystal layer; the liquid crystal layer has a first region close to the injection port and a second region far from the injection port; and the first region has a high polymer density and has a pretilt angle in a direction opposite to the alignment regulating force, and the second region has a pretilt angle in the same direction as the alignment regulating force.
