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.

Claim (Index 1):
A head-up display device comprising:\n a light-emitting device capable of emitting an image to be projected onto a projection surface; a reflecting mirror reflecting light emitted from the light-emitting device; and a screen on which the light reflected by the reflecting mirror is focused and through which the light passes, wherein the reflecting mirror has at least first and second reflecting surfaces, the light emitted from the light-emitting device being incident on the first and second reflecting surfaces, one and the other of the first and second reflecting surfaces are a flat surface and a curved surface or curved surfaces having different shapes, the screen includes a first screen through which the light reflected by the first reflecting surface passes and a second screen through which the light reflected by the second reflecting surface passes, the first screen and the second screen are disposed so that a length of a first optical path in which the light having passed through the first screen reaches the projection surface is different from a length of a second optical path in which the light having passed through the second screen reaches the projection surface, and when the light reflected by the first reflecting surface that is a curved surface and/or the second reflecting surface that is a curved surface is curved surface reflected light, a lens capable of converging light is provided between the screen through which the curved surface reflected light passes and the light-emitting device.
