During assembly, the protrusion 416 is slid into the sliding groove 426 in a horizontal sliding manner in the view direction of fig. 9, so as to horizontally slide and assemble the first frame 41 and the second frame 42. In this assembly type, the first fixing holes 417 are screw holes, the second fixing holes 427 are through holes, the frame 4 further has a plurality of screw members 43, each screw member 43 passes through the corresponding first fixing hole 417 and the corresponding second fixing hole 427 and is locked in the second fixing hole 427, so as to lock and fix the first frame 41 and the second frame 42 overlapped with each other.

Besides the structure shown in fig. 16, the locking and fixing manner using the screw elements 43 can also be that, as shown in fig. 17, each first combination element 412 further has a rivet bolt 418 disposed on the projection 416, and each second combination element 422 further has a second fixing hole 427 formed on the second combination element 422 and communicated with the sliding groove 426. In this assembly type, the second fixing holes 427 are designed as through holes, and after the first frame 41 and the second frame 42 are overlapped, each screw 43 passes through the corresponding second fixing hole 427 and the corresponding rivet 418 and is locked to the rivet 418, so as to lock and fix the overlapped first frame 41 and the overlapped second frame 42.

As can be seen from the above description, the combination of the frame 4 of the display device of the present invention not only simplifies the combination procedure and assembly of the first frame 41 and the second frame 42, but also provides various combination possibilities. Connecting pieces do not need to be additionally used between the frames, and the number of assembly components is reduced. And the panel C can not be shielded by the frame, thereby meeting the requirement of narrow frame. Moreover, after the first frame 41 and the second frame 42 are combined and then the adhesive member B is attached, the joint portion can be hidden under the panel C, thereby improving the overall aesthetic degree. In addition, since the joint is designed in the thickness direction of the first frame 41 and the second frame 42, and the joint is formed in a concave-convex manner, and no protrusion is formed in the thickness direction, which is helpful for the thinning effect of large-sized products such as televisions, the object of the present invention can be achieved.

However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the description of the present invention should be included in the scope of the claims of the present invention.
