AI summary

A liquid crystal element includes: a first substrate on which element sets each including an electric resistance film, a first electrode, and a second electrode are disposed, the first and second electrodes being electrically coupled to the electric resistance film; a second substrate on which third electrodes and fourth electrodes are disposed; and a liquid crystal layer between the first substrate and the second substrate. The electric resistance film extends in a first direction. The first and second electrodes extend in the first direction, face each other in a second direction, and overlap the electric resistance film. The element sets are arranged in the second direction. Each third electrode extends in the first direction and overlaps the first electrode of a corresponding one of the element sets. Each fourth electrode extends in the first direction and overlaps the second electrode of a corresponding one of the element sets.
