Abstract

A vehicle pane, includes successively a) an outer glass pane, b) at least one laminated layer, c) a PDLC layer, including a polymer matrix, in which liquid crystal droplets are embedded, and in each case an electrically conductive layer on both sides of the polymer matrix, d) at least one laminated layer, and e) an inner glass pane. The TL(inside) is in the range from 5 to 46% and the TL(outside) is in the range from 20 to 73% and the TL(outside) is greater than or equal to TL(inside), wherein the TL(inside) is the light transmittance of an inner stack that is formed by the inner glass pane and the layers between the PDLC layer and the inner glass pane, and TL(outside) is the light transmittance of an outer stack that is formed by the outer glass pane and the layers between the PDLC layer and the outer glass pane.
