Lighting device

A lighting device comprising;

• a light source having a first optical element and a second optical element emitting directional light;
• and
• one liquid crystal optical element transmitting or diffusing the light emitted from the light source;
• wherein
• the first optical element includes a first light exit surface, the second optical element includes a second light exit surface, and the first light exit surface and the second light exit surface are arranged to direct in different directions,
• the liquid crystal optical element has a first electrode group facing the first light exit surface and a second electrode group facing the second light exit surface and arranged adjacent to the first electrode group,
• the first electrode group has a first transparent electrode and a second transparent electrode arranged alternately with the first transparent electrode,
• the second electrode group has a third transparent electrode and a fourth transparent electrode arranged alternately with the third transparent electrode, and
• a pitch at which the first transparent electrode and the second transparent electrode are alternately arranged is different from a pitch at which the third transparent electrode and the fourth transparent electrode are alternately arranged.
