The present invention relates to a windscreen (10) having an upper edge (O) and a lower edge (U), comprising an outer pane (1) with an exterior surface (I) and an interior surface (II) and comprising an inner pane (2) with an exterior surface (III) and an interior surface (IV), wherein the interior surface (II) of the outer pane (1) and the exterior surface (III) of the inner pane (2) are connected to one another by way of a thermoplastic intermediate layer (3), wherein the interior surface (IV) of the inner pane (2) is provided with a reflection coating (20), which is suitable for reflecting p-polarized radiation and which comprises the following, in the order specified, starting from the interior surface (IV) of the inner pane (2): - an optically highly refractive layer (21) with a refractive index greater than or equal to 1.9, - at least in some parts, a reflection-increasing layer (22) on the basis of a metal, semiconductor, an electrically conductive carbide or an electrically conductive nitride, - an optically lowly refractive layer (23) with a refractive index of less than or equal to 1.6, wherein the windscreen (10) has at least a first subregion (F) and a second subregion (G), wherein the first subregion (F) is at a smaller distance from the lower edge (U) than the second subregion (G) and wherein the layer thickness of the reflection-increasing layer (22) in the first subregion (F) is greater than the layer thickness of the reflection-increasing layer (22) in the second subregion (G).
