Abstract

There is provided a vehicular display device including: a display unit configured to emit a display image including display light and projected onto a projection target member provided in a vehicle; a first optical component configured to reflect the display light emitted from the display unit; a first case having a space configured to accommodate the first optical component; and a second case configured to press the first optical component accommodated in the space against the first case.

First claim

What is claimed is:

1 . A vehicular display device comprising:
a display unit configured to emit a display image including display light, the display image projected onto a projection target member provided in a vehicle; a first optical component configured to reflect the display light emitted from the display unit; a first case having a space configured to accommodate the first optical component; a second case configured to press the first optical component accommodated in the space against the first case, the first optical component being fixed by being pressed against the first case; and an elastic member comprising packing and provided between the first optical component and the second case, wherein the packing is provided on the second case in a position in contact with the first optical component and the second case, wherein the first case is fixed to the second case with the first optical component interposed therebetween, wherein the first optical component has a back surface and is bonded, via an adhesive, to the space, and wherein the second case is configured to press the first optical component accommodated in the space via the packing against the first case.

2 . The vehicular display device according to claim 1 , further comprising:
a light shielding wall that is provided on a first optical path along which external light coming from outside of the vehicle reaches the display unit and at a position avoiding a second optical path from the display unit to the first optical component.

3 . The vehicular display device according to claim 1 , further comprising:
a housing that covers the display unit, the first optical component, the first case, and the second case and has an opening; and a second optical component configured to reflect the display light reflected by the first optical component, wherein the display light reflected by the second optical component reaches the projection target member through the opening.

4 . The vehicular display device according to claim 1 , wherein the space has a shape substantially conforming to an outer shape of the first optical component.

5 . The vehicular display device according to claim 1 , wherein the first case is fixed to the second case by screws.
