Abstract: Provided is a light absorber. The light absorber includes a reflective layer having conductivity, a conductive pattern disposed on the reflective layer and including at least one first opening, a nano-antenna disposed on the reflective layer and vertically overlapping the first opening, and an insulating pattern interposed between the reflective layer and the conductive pattern and between the reflective layer and the nano-antenna. The reflective layer, the conductive pattern, and the nano-antenna are electrically insulated from each other.
