摘要

A vehicular display device includes: an emitting portion; a reflection portion configured to reflect the display light that is emitted from the emitting portion and is subjected to crossing, to a display surface such that the display light is reflected from the display surface to a previously defined eye point; and a casing including: an inner case; and a lower case housing the inner case inside, in which the inner case includes an inner wall part facing a focal area on which external light reflected from the reflection portion after being incident on the reflection portion from outside the casing focuses, the lower case includes a lower wall part located along the inner wall part, and the casing has a heat-discharge structure of conducting heat from the inner wall part to the lower wall part to discharge the heat outward.

說(shuō)明書(shū)

The emitting portion 2 is a display device that is equipped in the vehicle V and is capable of emitting the display light L1. The emitting portion 2 is provided inside the casing 4. The display light L1 that the emitting portion 2 emits achieves the display image VI that is displayed on the windshield WS, and includes at least light having visible-light components. Examples of a device that emits the display light L1 as the emitting portion 2 include a laser projector, a thin liquid-crystal display, a plasma display, an organic EL display, an optical indicator, and a fluorescent display. Herein, the emitting portion 2 is provided on the back side in the vehicular forward and backward direction X inside the casing 4. The emitting portion 2 is supported inside the casing 4 such that the optical-axis direction of the display light L1 that the emitting portion 2 emits (direction along the optical axis AX) is oriented to the front side in the vehicular forward and backward direction X. The emitting portion 2 emits (projects) the display light L1 to the front side in the vehicular forward and backward direction X.
