PROBLEM TO BE SOLVED: To provide a head-up display device capable of preventing external light from being excessively focused in the inside of a housing.SOLUTION: A head-up display device 101 includes: a laser light source LD for emitting light of a predetermined wavelength; an image generation part 11 for generating an image with light from the laser light source LD; a concave mirror 22 which enlarges the image generated by the image generation part 11 and projects it to windshield WS; and an optical filter F5 which is disposed at a predetermined optical path between the image generation part 11 and the concave mirror 22; and an optical confinement structure 60 which is disposed outside of the predetermined optical path. The optical filter F5 is disposed at a position where external light DL reflected by the concave mirror 22 after passing through the windshield WS and reaching the optical filter F5 is reflected toward a space SP1 in the optical confinement structure 60.SELECTED DRAWING: Figure 3

    【課題】外光が筐体内部で過度に集光されてしまうのを防止できるヘッドアップディスプレイ装置を提供すること。【解決手段】ヘッドアップディスプレイ装置101は、所定波長の光を発するレーザ光源LDと、レーザ光源LDからの光で画像を生成する画像生成部11と、画像生成部11が生成した画像を拡大してウインドシールドWSに投影する凹面ミラー22と、画像生成部11と凹面ミラー22との間の所定光路内に配置された光学フィルタF5と、所定光路の外に配置された光閉じ込め構造60とを有する。光学フィルタF5は、ウインドシールドWSを通り凹面ミラー22で反射して光学フィルタF5に至る外光DLを光閉じ込め構造60内の空間SP1に向けて反射させる位置に配置されている。【選択図】図3
