Abstract
A light modulator of to this embodiment enables high-speed modulation to an SLM using a liquid crystal. The light modulator comprises refractive index regions arranged in a first direction on a reference plane, a region surrounding each refractive index regions and having a refractive index lower than that of each refractive index region, a first conductive film, and a second conductive film. The first conductive film is provided on any one of a pair of side surfaces arranged in the first direction in at least one refractive index region selected from the refractive index regions and belonging to a first group. The second conductive film is provided on any one of the pair of side surfaces so as not to overlap with the first conductive film in at least one refractive index region selected from the refractive index regions and belonging to a second group.
