Abstract

A display device includes a display device main body, a first display surface, and a second display surface, and the display device main body includes a first emitting portion, a second emitting portion, and a housing accommodating them. The first emitting portion emits first display light. The first display surface is provided on a transmission member transmitting light and reflects, to a viewing position side, the first display light being emitted from the first emitting portion. The second emitting portion emits second display light that is different from the first display light. The second display surface is provided on a non-transmission member shielding light and forming at least a part of a light path of the first display light to the first display surface from the first emitting portion and reflects, to the viewing position side, the second display light being emitted from the second emitting portion.

Claims (33)

1. A display device comprising:

a first emitting portion, that is a first body, that emits first display light;

a first display surface provided on a transmission member transmitting light and reflecting, to a viewing position side, the first display light being emitted from the first emitting portion;

a second emitting portion that is a second body provided separately from the first emitting portion that is the first body, and the second emitting portion emits second display light that is different from the first display light;

a second display surface facing the viewing position side, provided on a non-transmission member shielding light and forming at least a part of a light path of the first display light to the first display surface from the first emitting portion, and reflecting, to the viewing position side, the second display light being emitted from the second emitting portion; and

a reflection portion that reflects, to the first display surface side, the first display light being emitted from the first emitting portion, wherein

the second emitting portion is provided at a position opposing the second display surface in a direction opposite an emitting direction of the second display light and emits the second display light toward the second display surface directly, and

both of a first image that is displayed with the first display light on the first display surface and a second image that is displayed with the second display light on the second display surface are virtual images.

2. The display device according to claim 1 , further comprising:

a housing that defines an accommodation space portion inside accommodating the first emitting portion and the second emitting portion.

3. The display device according to claim 2 , wherein

the first emitting portion and the second emitting portion are provided at an opposite side to the second display surface with the light path interposed.

4. The display device according to claim 2 , wherein the light-shielding member, that shields light, is a light path formation wall body on which the second display surface is provided.

5. The display device according to claim 1 , wherein

the first emitting portion and the second emitting portion are provided at an opposite side to the second display surface with the light path interposed.

6. The display device according to claim 1 , wherein

a distance from a viewing position, on the viewing position side, to the second display surface is longer than a distance from the viewing position to the first display surface.

7. The display device according to claim 1 , wherein

a path of the first display light, towards the first display surface from the reflection portion, crosses a path of the second display light, towards the second display surface from the second emitting portion, in a projection plane extending in front-rear directions and height directions of the display device, and

the path of the first display light and the path of the second display light cross, in the projection plane, at a position between the reflection portion and the second emitting portion, along the front-rear directions.

8. The display device according to claim 1 , wherein

the first display light and the second display light are emitted from the first emitting portion and the second emitting portion, respectively, in respective directions away from the viewing position side.

9. A display device main body comprising:

a first emitting portion, that is a first body, configured to emit first display light toward a first display surface provided on a transmission member transmitting light;

a second emitting portion that is a second body provided separately from the first emitting portion that is the first body, and the second emitting portion being configured to emit second display light that is different from the first display light toward a second display surface facing a viewing position side, provided on a non-transmission member shielding light, and forming at least a part of a light path of the first display light to the first display surface from the first emitting portion;

a reflection portion that reflects, to the first display surface side, the first display light being emitted from the first emitting portion; and

a housing that defines an accommodation space portion inside accommodating the first emitting portion, the reflection portion, and the second emitting portion, wherein

the housing is installed at such a position that the first display surface reflects, to the viewing position side, the first display light being emitted from the first emitting portion and the second display surface reflects, to the viewing position side, the second display light being emitted from the second emitting portion,

the second emitting portion is provided at a position opposing the second display surface in a direction opposite an emitting direction of the second display light and emits the second display light toward the second display surface directly, and

both of a first image that is displayed with the first display light on the first display surface and a second image that is displayed with the second display light on the second display surface are virtual images.

10. The display device main body according to claim 9 , wherein

a path of the first display light, towards the first display surface from the reflection portion, crosses a path of the second display light, towards the second display surface from the second emitting portion, in a projection plane extending in front-rear directions and height directions of the display device main body, and

the path of the first display light and the path of the second display light cross, in the projection plane, at a position between the reflection portion and the second emitting portion, along the front-rear directions.
