the first portion comprises a top wall which circumferentially surrounds an annular side wall having a notch, and the annular side wall is provided with a terminal hole corresponding to a connection terminal on a mainboard of the display device; and
the second portion is provided on a notch side of the first portion, and the second portion comprises a central portion corresponding to the notch of the first portion, and side portions on opposite sides of the central portion, the central portion is provided with a connection wall covering the notch, and the connection wall is provided with a terminal hole corresponding to a connection terminal on the mainboard of the display device;
wherein the first portion and the second portion are snap-fitted;
wherein the annular side wall comprises two first connection surfaces facing the second portion, each of the first connection surfaces being recessed to form a neck, and the second portion comprises a second connection surface facing the first portion, the second connection surface being provided with a protrusion capable of being snapped into the neck.

2. The rear housing of the display device according to claim 1 , wherein a groove is provided on the annular side wall, a bottom surface of the groove is connected to the top wall, and the terminal hole is provided at the bottom surface of the groove.

3. The rear housing of the display device according to claim 1 , wherein each of the side portions is convex in a first direction, opposite side surfaces of both of the side portions are joined to the central portion and the connection wall to enclose a groove, the first direction is a direction from a side of the connection wall remote from the top wall to a side of the connection wall proximate to the top wall.

4. The rear housing of a display device according to claim 1 , wherein the first portion is integrally injection molded.

5. The rear housing of the display device according to claim 1 , wherein the second portion is integrally injection molded.

6. The rear housing of the display device according to claim 3 , wherein both of the side portions are symmetrically arranged with the central portion as a center.

7. The rear housing of the display device according to claim 6 , wherein a sound outlet hole is provided on an outer side surface adjacent to the side surfaces on each of the side portions.

8. A display device comprising:
mainboard provided with a connection terminal;
backboard comprising a first region for mounting the mainboard and a second region for mounting an electronic component; and
a rear housing , wherein the rear housing comprises a first portion corresponding to the first region of the backboard of the display device and a second portion corresponding to the second region of the backboard of the display device;
the first portion comprises a top wall which circumferentially surrounds an annular side wall having a notch, and the annular side wall is provided with a terminal hole corresponding to a connection terminal on a mainboard of the display device; and
the second portion is provided on a notch side of the first portion, and the second portion comprises a central portion corresponding to the notch of the first portion, and side portions on opposite sides of the central portion, the central portion is provided with a connection wall covering the notch, and the connection wall is provided with a terminal hole corresponding to a connection terminal on the mainboard of the display device;
wherein the first portion is snap-fitted over the first region to form a first receiving cavity for receiving the mainboard, and the second portion is snap-fitted over the second region to form a second receiving cavity for receiving the electronic component;
wherein the first portion and the second portion are snap-fitted;
wherein the annular side wall comprises two first connection surfaces facing the second portion, each of the first connection surfaces being recessed to form a neck, and the second portion comprises a second connection surface facing the first portion, the second connection surface being provided with a protrusion capable of being snapped into the neck.

9. The display device according to claim 8 wherein the electronic component comprises a speaker, each of side portions of the second portion is convex in a first direction such that each of the side portions is snap-fitted with the backboard to form the second receiving cavity for receiving the speaker, and each of the side portions is provided with a sound outlet hole on an outer side surface remote from the first portion.

10. The display device according to claim 8 , wherein the backboard and the rear housing are fixed by bolts.

11. The display device according to claim 8 , wherein a groove is provided on the annular side wall, a bottom surface of the groove is connected to the top wall, and the terminal hole is provided at the bottom surface of the groove.

12. The display device according to claim 8 , wherein each of the side portions is convex in a first direction, opposite side surfaces of both of the side portions are joined to the central portion and the connection wall to enclose a groove, the first direction is a direction from a side of the connection wall remote from the top wall to a side of the connection wall proximate to the top wall.

13. The display device according to claim 8 , wherein the first portion is integrally injection molded.

14. The display device according to claim 8 , wherein the display device includes a liquid crystal television, a liquid crystal display, a digital photo frame, a mobile phone, or a tablet computer.
