1. A displaying module, the displaying module comprising 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, wherein the plastic frame is of a shape of an annular frame, and the plastic frame comprises a bearing face, a bottom face opposite to the bearing face, and an inner annular face perpendicular to the bottom face;
the display panel covers the bearing face, the bottom face abuts the back plate, and the light guide plate is fixed in a fixing space enclosed by the inner annular face; and
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,
wherein the plastic frame is a square plastic frame, four corners of the plastic frame include at least one curved-surface corner, a bearing face of the curved-surface corner is a curved surface, and a length of two sides intersecting at the curved-surface corner is a first length, wherein the first length is a distance between two facing lateral sides of the region of the display panel where light leakage happens, and
wherein the curved-surface corner comprises a first warping face and a second warping face,
the first warping face and the second warping face intersect, a projection of the first warping face in a direction perpendicular to a displaying face of the display panel is located at a position where a longer side edge of the display panel is located, and a projection of the second warping face in the direction perpendicular to the displaying face of the display panel is located at a position where a shorter side edge of the display panel is located, wherein the longer side edge and the shorter side edge are two intersecting sides of the display panel, and a length of the longer side edge is greater than a length of the shorter side edge, and
both of the first warping face and the second warping face curve in the direction further away from the display panel.
