According to one embodiment, a display includes a projector, a first optical unit, and a second optical unit. The projector emits a first light including image information. The first optical unit transmits at least a portion of a second light. The second optical unit reflects at least a portion of the first light and transmits at least a portion of the second light. A light reflectance of the first optical unit is lower than a light reflectance of the second optical unit, and a light absorptance of the first optical unit is higher than a light absorptance of the second optical unit.
