Title: DISPLAY DEVICE AND MOVING BODY CARRYING DISPLAY DEVICE
Abstract:
The present invention provides a display device capable of suppressing a decrease in the resolution of a virtual image, and a moving body carrying the display device. An irradiation part (3) in the display device includes an imaging optical system (323). The imaging optical system (323) scans and irradiates the surface of a screen (1) with light to thereby form an image. Light that passes through the screen (1) and exits from the screen (1) along the moving direction thereof is incident on a projection part (4) as incidence light. The projection part projects the incidence light onto a reflection member and the reflection member reflects the incidence light to thereby project a virtual image corresponding to the image in a target space. The locus of a focal position (Pf1) of the imaging optical system (323) when the irradiation part (3) scans the entire surface of the screen (1) is within a range between the surface of the screen at a first position (Po1) and the surface of the screen at a second position (Po2).
