The invention discloses a display assembly and a rearview mirror display screen, and relates to the field of display screens. The display assembly comprises a cholesteric liquid crystal layer, a quarter-wave plate, a linear polarizer and a display module which are sequentially stacked, under the condition that the cholesteric liquid crystal layer is powered on, display light emitted by the display module sequentially penetrates through the linear polaroid, the quarter-wave plate and the cholesteric liquid crystal layer, so that the display assembly has a display function. Under the condition that the cholesteric liquid crystal layer is powered off, display light emitted by the display module sequentially penetrates through the linear polarizer and the quarter-wave plate and is reflected on the side, facing the quarter-wave plate, of the cholesteric liquid crystal layer, and ambient light is reflected on the side, deviating from the quarter-wave plate, of the cholesteric liquid crystal layer. The rearview mirror display screen comprises the display assembly. The problems that the contrast ratio of a displayed image is poor, negative influences are caused to a driver wearing a polarized lens, and the cost of a current reflection type polaroid is high can be solved.

    本申请公开了一种显示组件及后视镜显示屏,涉及显示屏领域。一种显示组件包括:依次叠置的胆甾相液晶层、四分之一波片、线偏振片和显示模组;在胆甾相液晶层通电的情况下,显示模组发出的显示光依次透过线偏振片、四分之一波片和胆甾相液晶层,以使显示组件呈现显示功能;在胆甾相液晶层断电的情况下,显示模组发出的显示光依次透过线偏振片和四分之一波片,并在胆甾相液晶层朝向四分之一波片的一侧发生反射,且环境光在胆甾相液晶层背离四分之一波片的一侧发生反射。一种后视镜显示屏,包括上述显示组件。本申请能够解决显示图像对比度差、对佩戴偏振镜片的驾驶员造成负面影响,以及当前反射式偏振片成本高等问题。
