Summary:The utility model relates to a curing screen capable of preventing expansion on heating and contraction on cooling, which consist of a screen body, an auxiliary component and a screen frame. The screen frame is connected to the inner surface of the screen body, the auxiliary component is arranged at the upper end of the screen body, a cylindrical mirror is arranged on the outer surface of the screen body, an adhesive layer b is arranged between the cylindrical mirror and the screen body, the screen body is composed of two optical white glass layers and a Fresnel lens arranged between the two optical white glass layers, and the cylindrical mirror is arranged on the outer surface of the optical white glass layer b. The curing screen is reasonable in structure design. Since the cylindrical mirror is attached onto the whole surface of the optical white glass through adhesive, the problem of expansion on heating and contraction on cooling of an imaging layer is solved, and simultaneously frequent light leakage of
