The invention provides a display device, a head-up display and a motor vehicle. The display device comprises a light source part, a converging element, a diffusing element, a liquid crystal display panel and a reflecting element; the light source part is configured to emit light, and the light emitted from the light source part passes through the converging element, the diffusing element, the liquid crystal display panel and the reflecting element and then reaches a first preset area; the converging element is configured to converge the light passing through the converging element; the diffusion element is configured to diffuse the light beam passing through the diffusion element without changing the optical axis of the light beam; the liquid crystal display panel is configured to convertthe received light into image light to be emitted; the reflection element is configured to reflect the image light and converge the image light; the converging element is configured to converge the light emitted by the light source part to a second predetermined area in the first predetermined area under the condition that the diffusion element is removed from the light path from the light sourcepart to the first predetermined area, and the area of the second predetermined area is smaller than that of the first predetermined area. The display device can reduce power consumption and improve brightness.

    提供一种显示装置、抬头显示器和机动车。该显示装置包括光源部、汇聚元件、扩散元件、液晶显示面板和反射元件;光源部被配置为出射光,从光源部出射的光经过汇聚元件、扩散元件、液晶显示面板以及反射元件后到达第一预定区域;汇聚元件被配置为汇聚经过汇聚元件的光;扩散元件被配置为扩散经过扩散元件的光束但不改变该光束的光轴;液晶显示面板被配置为将其接收到的光转变为图像光出射;反射元件被配置为反射图像光并将图像光进行汇聚;汇聚元件被配置为在从光源部至第一预定区域的光路中去除扩散元件的情况下,将光源部出射的光聚集到第一预定区域内的第二预定区域,第二预定区域的面积小于第一预定区域的面积。显示装置可降低功耗,提高亮度。
