A head-up display device (10) is provided with: one image forming unit (20) that emits first light (L1) and second light (L2); and an optical path adjustment unit (40) that is disposed on the optical path of at least one of the first light (L1) and the second light (L2), has light transmissivity, and has an optical power of substantially zero. The optical path adjustment unit (40) gradually separates the first light (L1) and the second light (L2) from each other than before the first light (L1) and/or the second light (L2) enters the optical path adjustment unit (40), so that the first light (L1) becomes a first virtual image (V1) that appears in the vicinity when viewed from the driver, and the second light (L2) becomes a second virtual image (V2) that appears further than the first virtual image (V1) when viewed from the driver.
平视显示器装置(10)具备:一个图像形成单元(20),其分别射出第一光(L1)及第二光(L2);光路调整部(40),其配置在第一光(L1)及第二光(L2)中的至少一方的光路上,具有光透射性且光学功率大致为零。光路调整部(40)使第一光(L1)及第二光(L2)与第一光(L1)及第二光(L2)中的至少一方向光路调整部(40)入射之前相比逐渐分离,以使得第一光(L1)成为在从驾驶员观察时出现在近处的第一虚像(V1),第二光(L2)成为在从驾驶员观察时出现在比第一虚像(V1)靠远处的第二虚像(V2)。
