Optical member

An optical member comprising

• a light guide body including:
• a first hologram configured to interfere and refract a light that is incident from a blind area;
• a plurality of reflecting surfaces configured to reflect the light that is refracted by the first hologram;
• a smooth surface configured to reflect the light that is reflected by the plurality of reflecting surfaces;
• and
• a plurality of second holograms disposed on the plurality of reflecting surfaces and configured to interfere and refract the light that is refracted by the first hologram and the light that is reflected by the smooth surface to emit the lights to an outside of the light guide body, wherein
• the plurality of second holograms is arranged at an interval in a first direction that intersects a normal direction of the plurality of reflecting surfaces and is arranged at an interval in a second direction that intersects the normal direction and the first direction, and
• each of the plurality of reflecting surfaces is positioned between two of the plurality of second holograms adjacent to each other such that the plurality of reflecting surfaces is arranged at an interval in the first direction and is arranged at an interval in the second direction.

An optical member comprising:

• a light guide body including:
• an incident surface on which a light from a blind area is incident;
• a plurality of reflecting surfaces configured to reflect the light that is guided from the incident surface;
• a smooth surface configured to reflect the light that is reflected by the plurality of reflecting surfaces;
• and
• a plurality of prisms protruding from the plurality of reflecting surfaces in a normal direction of the plurality of reflecting surfaces and configured to emit the light that is guided from the incident surface and the light that is reflected by the smooth surface to an outside of the light guide body;
• and
• a plurality of light shielding portions configured to block a light that is directed toward the plurality of prisms from the outside of the light guide body, wherein
• the plurality of prisms is arranged at an interval in a first direction that intersects the normal direction and is arranged at an interval in a second direction that intersects the normal direction and the second direction,
• each of the plurality of reflecting surfaces is positioned between two of the plurality of prisms adjacent to each other such that the plurality of reflecting surfaces is arranged at an interval in the first direction and is arranged at an interval in the second direction,
• the plurality of light shielding portions is arranged at an interval in the first direction and is arranged at an interval in the second direction.
