Abstract
The purpose of the present invention is to provide a compact and low-cost head-up display device capable of creating a sense of depth in a virtual image. This head-up display device includes a light-emitting device, a reflecting mirror, and a screen. The reflecting mirror includes two reflecting surfaces that are a first reflecting surface having a flat shape and a second reflecting surface having a curved shape. The screen is composed of a first screen through which the light reflected from the first reflecting surface passes, and a second screen through which the light reflected from the second reflecting surface passes. The first screen and the second screen are disposed so that the length of a first optical path in which the light emitted from the light-emitting device reaches the first screen is different from the length of a second optical path in which the light emitted from the light-emitting device reaches the second screen.
