Abstract

A display device for a vehicle includes: a substrate housing portion that stores a circuit substrate that outputs an image signal of an image to be displayed; an optical unit that generates and projects an image based on the image signal; and a combiner on which the image is projected, wherein the optical unit has: an optical unit main body that includes a light source and an image display element; and a projection unit that determines a projection direction, wherein the optical unit main body has a first main body surface and a second main body surface, and wherein the projection unit has two arrangement states: a first state where a projection port of the projection unit is on the side of the first main body surface; and a second state where the projection port is on the side of the second main body surface.

Claims

1. A display device for a vehicle comprising:

a substrate housing portion that stores a circuit substrate that outputs an image signal of an image to be displayed;

an optical unit that is provided at one end of the substrate housing portion and that generates and projects an image based on the image signal output from the circuit substrate; and

a combiner that is provided at one end of the optical unit and on which the image is projected,

wherein the optical unit has;

an optical unit main body that includes a light source and an image display element; and

a projection unit that is attached to the optical unit main body, that includes a projection mirror and an intermediate image screen that forms a real image, and that determines a projection direction,

wherein the optical unit main body has a first main body surface and a second main body surface, which is a surface facing the first main body surface, and

wherein the projection unit has two arrangement states;

a first state where a projection port of the projection unit is on the side of the first main body surface; and

a second state where the projection port is on the side of the second main body surface.

2. The display device for a vehicle according to claim 1,

wherein the projection unit and the combiner are each detachably attached to the optical unit main body.

3. The display device for a vehicle according to claim 1,

wherein the image display element outputs an image according to the position of the projection port.

4. The display device for a vehicle according to claim 1,

wherein the substrate housing portion has a first attachment surface on the same side as the first main body surface and has a second attachment surface, which is a surface facing the first attachment surface.

5. The display device for a vehicle according to claim 4,

wherein the first attachment surface or the second attachment surface is attached to a rear-view mirror inside the vehicle using an attachment member.
