Abstract: The light detector includes a light detection substrate having at least one light receiving region and a light incident surface on which a detection target light is incident, and a meta-lens including a plurality of unit structures arranged in a grid pattern and disposed on the light incident surface to focus the detection target light. When viewed in a thickness direction of the light detection substrate, an opening region in which no unit structure is formed is provided in a region including a center of the meta-lens.
