  • Patent number: 10781992
    Abstract: To facilitate lead wiring layout corresponding to an increase in the number of individual electrodes of the liquid crystal element in a vehicle headlamp system. The vehicle headlamp system that selectively performs light irradiation towards the periphery of its own vehicle includes a light source, a liquid crystal element, and a lens. The liquid crystal element includes a plurality of first individual electrode parts, a plurality of second individual electrode parts, and a first lead wiring part. The first lead wiring part includes a plurality of first individual wirings each of which is connected to one of the plurality of first individual electrode parts, and a plurality of second individual wirings each of which is connected to one of the plurality of second individual electrode parts and arranged through a gap formed between the adjacent first individual electrode parts in the first direction.
