The invention provides a head-up display device and a motor vehicle. The head-up display device comprises a light source, a first light gathering element, a light diffusion element, a liquid crystal panel and a second light gathering element; the light source emits light, the light guide element comprises a light-emitting surface, the light-emitting surface faces the first light gathering element,and the light is transmitted through the interior of the light guide element and emitted to the first light gathering element from the light-emitting surface; the first light gathering element gathers the light and transmits the light to the liquid crystal panel; the liquid crystal panel converts the light into image light; the second light gathering element gathers the image light and reflects the image light to a first preset area; the light diffusion element diffuses the light gathered to the first preset area to the second preset area; the light guide element, the first light gathering element and the liquid crystal panel are sequentially arranged between the light source and the second light gathering element. The head-up display device can reduce power consumption while improving image brightness.

    本发明提供一种抬头显示装置和机动车,该抬头显示装置包括光源、第一光线聚集元件、光扩散元件、液晶面板和第二光线聚集元件;光源出射光线,导光元件包括出光面,出光面朝向第一光线聚集元件,光线经导光元件内部传输,从出光面出射至第一光线聚集元件;第一光线聚集元件将光线聚集,并传输至液晶面板;液晶面板将光线转化为图像光线;第二光线聚集元件将图像光线聚集,并将图像光线反射至第一预定区域;光扩散元件将聚集至第一预定区域的光线扩散至第二预定区域;导光元件、第一光线聚集元件及液晶面板依次设置在光源与第二光线聚集元件之间,抬头显示装置可在提升图像亮度的同时降低功耗。
