a heating element which is arranged within the opaque region of the at least one masking layer, and

a reflective layer adapted to reflect visible light,

wherein the reflective layer is arranged spatially in front of the at least one masking layer in the viewing direction from the inner pane to the outer pane and overlaps at least partially with the opaque region of the at least one masking layer.

2 . The laminated pane according to claim 1 , wherein the at least one masking layer further comprises a transparent region.

3 . The laminated pane according to claim 1 , wherein the thermoplastic intermediate layer contains the at least one masking layer and a transparent layer, and the at least one masking layer is completely opaque.

4 . The laminated pane according to claim 1 , wherein the at least one masking layer is arranged to be at least adjacent to a lower edge of the laminated pane.

5 . The laminated pane according to claim 1 , wherein the opaque region of the at least one masking layer is arranged in a frame-like, circumferential manner in an edge region of the laminated pane and, in a section which is in overlap with the reflective layer, has a greater width than in sections different therefrom.

6 . The laminated pane according to claim 1 , wherein

the reflective layer and the opaque region each have a surface, which are arranged congruently, or

the opaque region has a larger surface than the reflective layer, and the reflective layer overlaps completely with the opaque region.

7 . The laminated pane according to claim 1 , further comprising a first masking strip which is applied in regions on the inner side of the outer pane, and wherein at least the heating element overlaps completely with the first masking strip.

8 . The laminated pane according to claim 1 , wherein the reflective layer has an average transmission in the visible spectral range of at least 60%, and/or the reflective layer reflects at least 15% of the light incident on the reflective layer.

9 . The laminated pane according to claim 1 , further comprising a first busbar and a second busbar, which are provided for connection to a voltage source,

wherein the first and the second busbars are connected to an edge region of the heating element in such a way that a current path through the heating element for a heating current is formed between the first and second busbars.

10 . The laminated pane according to claim 1 , wherein the heating element is completely embedded in the opaque region of the at least one masking layer.

11 . The laminated pane according to claim 1 , wherein the heating element is designed in the form of heating wires which have a diameter of 10 μm to 300 μm.

12 . The laminated pane according to claim 11 , wherein the heating wires contain or consist of a metal.

13 . The laminated pane according to claim 1 , wherein a highly-refractive coating with a refractive index of at least 1.7 is arranged at least in one region of the inner side of the inner pane, which region is in overlap with the reflective layer, and wherein the highly-refractive coating is always arranged spatially in front of the reflective layer when looking onto the inner side of the inner pane.

14 . A projection arrangement comprising:

a laminated pane according to claim 1 ,

a display device assigned to the reflective layer and having an image display directed onto the reflective layer, the image of which image display is reflectable by the reflective layer,

wherein at least the region of the reflective layer which is in overlap with the opaque region of the at least one masking layer can be irradiated by the display device.

15 . A method for producing a laminated pane according to claim 1 , the method comprising:

(a) arranging the outer pane, the thermoplastic intermediate layer, the heating element, the reflective layer, and the inner pane to form a layer stack,

wherein the thermoplastic intermediate layer is arranged between the outer pane and the inner pane, and the heating element is arranged within the opaque region of the at least one masking layer, and

wherein the reflective layer is arranged spatially in front of the at least one masking layer in the viewing direction from the inner pane to the outer pane and overlaps at least partially with the opaque region of the at least one masking layer, and

(b) laminating the layer stack obtained to form a laminated pane.

16 . A method comprising providing a laminated pane according to claim 1 in a vehicle for traffic on land, in the air, or on water.

17 . The laminated pane according to claim 1 , wherein the laminated pane is a laminated pane of a projection arrangement.

18 . The laminated pane according to claim 2 , wherein the opaque region extends over less than 30% of a total surface of the laminated pane.

19 . The laminated pane according to claim 3 , wherein the at least one masking layer extends over less than 30% of a total surface of the laminated pane.

20 . The laminated pane according to claim 4 , wherein the at least one masking layer extends over at least 5% of a total surface of the laminated pane.
