A displaying module includes a back plate, a light guide plate fixed to the back plate, a plastic frame covering the back plate and a display panel located on the plastic frame, the plastic frame is of a shape of an annular frame, and the plastic frame includes a bearing face. A first position of the bearing face of the plastic frame is a curved surface, and the curved surface curves in a direction further away from the display panel, whereby a warping degree of the curved surface is a first warping degree, wherein the first position is a position of the bearing face that faces a second position of the display panel, the second position is a position of a region of the display panel where light leakage happens, and the first warping degree is equal to a warping degree of the display panel when the display panel curves.
