DISPLAY DEVICE |
| 摘要 |
According to one embodiment, a display device includes a display unit, a reflective/transmissive unit, and an optical unit. The display unit emits image light including image information. The reflective/transmissive unit reflects at least a portion of the image light and transmits at least a portion of background light. The optical unit is provided between the display unit and the reflective/transmissive unit in an optical path of the image light. A refractive power of the optical unit is determined according to a refractive power of the reflective/transmissive unit for the background light passing through the reflective/transmissive unit. |
