Abstract: Provided is an apparatus for molding a window, the apparatus including a mold in which a base window including a window bending part and a window flatness part is located and a cooling device configured to cool the base window. The window bending part includes a first bending surface and a second bending surface, which face each other. The cooling device includes a first cooling part configured to cool the first bending surface by using a cooling source having a first temperature, a second cooling part configured to cool the second bending surface by using a cooling source having a second temperature, and a third cooling part configured to cool the window flatness part. The first bending surface has an area greater than that of the second bending surface, and the first temperature is less than the second temperature.
