The frame part 2 is a non-metal part, and the middle frame part 2 includes at least one sub-middle frame part 21 , each sub-middle frame part 2 is located at the edge of the cover plate part 1 , and each sub-middle frame part 21 is along the cover plate part 1 . The edge line extends, and the inner wall 20 of the sub-middle frame portion is suitable for connecting with the outer peripheral wall of the display module. On the section plane of the sub-middle frame portion 21, the inner wall 20 of the sub-middle frame portion is formed as a straight line segment, and the included angle between the straight line segment and the central axis 10 of the cover plate portion is β, and β satisfies: 0°<β≤45 °, and on the sectional plane of the sub-middle frame portion 21, the straight line segment extends inwardly in a direction away from the cover plate portion 1, wherein the sectional plane of the sub-middle frame portion 21 is perpendicular to the sub-middle frame portion 21.
