The invention relates to a vehicle window (11), in particular a window in a vehicle roof (10), comprising a composite structure with a window outer body (16), a shading assembly (20), a window inner body (18) and a light-guiding layer (40), wherein the shading assembly (20) is arranged between the window outer body (16) and the window inner body (18), and comprises a switchable liquid crystal assembly (26). The shading assembly (20) comprises a carrier layer (15) which is arranged directly or indirectly on an outer side (41) of the light-guiding layer (40) orientated in the direction of the shading assembly (20), and which has a coating (17) made of a material with a refractive index n2, which is lower than a refractive index n1 of a material from which the light-guiding layer (40) is made.
A vehicle pane comprising a laminate construction having a pane outer body, a shading assembly, a pane inner body and a light guide layer wherein the shading assembly is arranged between the pane outer body and the pane inner body and comprises a switchable liquid crystal assembly, characterized in that the shading assembly comprises a carrier layer which is arranged directly or indirectly on an outer surface of the light guide layer oriented toward the shading assembly and comprises a coating made of a material having a refractive index n2 which is lower than a refractive index n1 of a material from which the light guide layer is made.
The vehicle pane as claimed in 10, characterized in that the incoupling element is a material body transparent to the light of the light source and is bar-like and/or has a wedge-shaped or trapezoidal cross section.
