Abstract
An optical device of the present invention includes a display apparatus and an optical system. The display apparatus includes a display region and a sensor region. The optical system includes a first mirror and a second mirror. The first mirror includes a first surface and a second surface. The display region has a function of emitting first light. The first mirror is provided on an optical path of the first light and has a function of transmitting the first light incident on the first surface to the second surface and a function of reflecting second light incident on the second surface. The second mirror is provided on an optical path of the second light and has a function of reflecting the second light. The sensor region has a function of detecting the second light via the first mirror and the second mirror.
