Original Abstract Submitted
A lighting device includes a light emitting module and an optical element including first and second liquid crystal cells. Each of the first and second liquid crystal cells includes first and second transparent electrodes extending in a first direction and third and fourth transparent electrodes extending in a second direction. The light emitting module includes a light source, a light guide plate including an end surface into which light emitted from the light source is incident and a first surface from which the light incident into the end surface is emitted, and a prism sheet disposed opposite to the first surface. The second substrate of the first liquid crystal cell and the first substrate of the second liquid crystal cell are adjacent to each other. The first surface includes a plurality of first grooves extending in a third direction intersecting the first direction and the second direction.
