The invention relates to a vehicle windscreen, in particular a windscreen of a roof, comprising a composite structure having a windscreen outer body (16) and a windscreen inner body (18, 18 '), and a shading assembly (20) which is arranged between the windscreen outer body (16) and the windscreen inner body (18) and which comprises a polymer dispersed liquid crystal layer (26) arranged between two plastic films (28, 30). At least one of the plastic film (28, 30) and/or the polymer dispersed liquid crystal layer (26) is provided with a black coloration such that the composite structure has a transmittance of less than 30% to visible light in a transmissive state of the liquid crystal layer and a transmittance of at most 8% to visible light in a blocked state.

    本发明涉及一种车辆挡风板,特别是车顶的挡风板,包括复合结构,所述复合结构具有挡风板外体(16)和挡风板内体(18,18')以及遮光组件(20),所述遮光组件布置在挡风板外体(16)和挡风板内体(18)之间并且包括布置在两个塑料膜(28,30)之间的聚合物分散液晶层(26)。所述塑料膜(28,30)和/或聚合物分散液晶层(26)中的至少一个设置有黑色着色,使得所述复合结构在所述液晶层的透过状态下对可见光具有小于30%透过率并且在阻断状态下对可见光具有最大8%的透过率。
