In some embodiments of the present disclosure, the flexible circuit boards may be disposed on the liquid crystal panel and opposite corresponding to B-B′ of the adhesive frame, and as illustrated in FIG. 1D and FIG. 2B, in order to cooperate with the liquid crystal panel 101 disposed with the flexible circuit board 104, to thereby prevent a damage to the flexible circuit board 104 being adhered, notches 1027 may be disposed on the limiting sections 1022 of the adhesive frame and opposite corresponding to the flexible circuit boards 104, so that the flexible circuit boards 104 may protrude the notches and be bent toward the connecting sections 1023. The number of notches 1027 may be the same as the number of flexible circuit boards 104. Since the limiting sections 1022 are configured to limit the liquid crystal panel 101 to horizontal movement, if the notches 1027 were not disposed, then the limiting sections 1022 would extrude the flexible circuit boards 104 when the liquid crystal panel were placed on the carrying sections 1021, thus easily resulting in a damage to the flexible circuit boards 104; and also first depressed sections 1024 depressed inward are disposed on the connecting sections 1023 and opposite corresponding to the notches 1027 to accommodate the flexible circuit boards 104, so that the first depressed sections 1024 depressed inward are disposed on the limiting sections and opposite corresponding to the flexible circuit boards 104, to thereby reserve some accommodation spaces for the flexible circuit boards, so that the flexible circuit boards 104 may be placed in the first depressed sections 1024.
