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.
