The present invention relates to a method for producing a windshield (10), the method at least comprising the following method steps: a) providing an outer pane (1) and an inner pane (2), b) heating the outer pane (1) and the inner pane (2) to at least their softening temperature, c) jointly bending the outer pane (1) and the inner pane (2) or individually bending the outer pane (1) and the inner pane (2), d) cooling the outer pane (1) and the inner pane (2), e) laminating the outer pane (1) and the inner pane (2) with the interposition of a thermoplastic intermediate layer (3) to form a laminated pane (10). In step d), the outer pane (1) and/or the inner pane (2) are/is cooled in the first surface region (X1) at a first cooling rate (A1), and the outer pane (1) and/or the inner pane (2) are/is cooled in the second surface region (X2) at a second cooling rate (A2), and the absolute value of the first cooling rate (A1) is greater than the absolute value of the second cooling rate (A2), the cooling rates (A1, A2) in the associated surface region (X1, X2) prevailing at at least one pane surface of the inner pane (2) and/or of the outer pane (1).
