A virtual image display device includes a backlight, a display panel, an optical system, and a backlight control unit. The backlight has a plurality of light-emitting parts and a light-emitting surface capable of emitting light from the plurality of light-emitting parts. The display panel has a display surface that displays an image by light emitted from the light-emitting surface. The optical system enlarges the image of the display surface and the image of the light-emitting surface at different magnifications so as to form a virtual image in the field of view of a user. The backlight control unit performs local dimming control by switching the plurality of light-emitting units to either a light-emitting state or a non-light-emitting state on the basis of an image displayed on the display panel. The size of the light-emitting surface is smaller than that of the display surface.

    虚像显示装置具备:背光灯、显示面板、光学系统以及背光灯控制部。背光灯具有:多个发光部和能够将来自多个发光部的光出射的发光面。显示面板具有通过从发光面出射的光来显示图像的显示面。光学系统以不同的倍率放大显示面的像以及发光面的像,使其在利用者的视野中成像为虚像。背光灯控制部根据显示于显示面板的图像,将多个发光部切换为发光状态以及非发光状态的任一个,进行局部调光控制。发光面的尺寸比显示面的尺寸小。
