  "textContent": "An optical member includes a light guide having: an incident surface on which an external scene light is incident from a blind area; a first reflecting surface that reflects light from the incident surface; and a second reflecting surface that reflects light reflected by the first reflecting surface. The optical member further includes a prism having: an exit surface that emits light from the incident surface and light reflected by the second reflecting surface to outside; and a light shielding surface connected to the exit surface to intersect the exit surface. A light from the incident surface and a light reflected by the second reflecting surface are incident on the light shielding surface. The light shielding surface has a rough surface, and a surface roughness of the rough surface is larger than a surface roughness of the exit surface.",
