while the stand neck is at the second position, the elastic block is engaged with the coupling hole.

6 . The supporting device of claim 2 , wherein the stand base and the stand neck are configured such that:

while the stand neck is at the first position, the elastic block is accommodated inside the second coupling body, and

while the stand neck is at the second position, the elastic block protrudes from the second coupling body.

7 . The supporting device of claim 2 , wherein

the second coupling portion includes a coupling protrusion on an outer side surface of the second coupling body, and

the first coupling portion includes:

a coupling groove in an inner side surface of the first coupling body and configured to guide the coupling protrusion, and

a locking protrusion configured to prevent, while the stand neck is at the second position, the coupling protrusion from departing from the coupling groove, the locking protrusion being adjacent to the coupling groove.

8 . The supporting device of claim 7 , wherein the coupling groove of the first coupling portion includes:

a first groove portion configured to accommodate the coupling protrusion while the stand neck is at the first position, and

a second groove portion extending from a lower part of the first groove portion and configured to accommodate the coupling protrusion while the stand neck is at the second position.

9 . The supporting device of claim 8 , wherein

the locking protrusion includes a first inclined portion inclined downward from the first groove portion toward the second groove portion, and

the coupling protrusion includes a second inclined portion corresponding to the first inclined portion.

10 . The supporting device of claim 8 , wherein the first coupling portion includes a fixing rib protruding toward the second groove portion to fix the coupling protrusion accommodated in the second groove portion.

11 . The supporting device of claim 1 , wherein the first coupling portion includes a fixing rib on an inner side surface of the first coupling body to fix, while the second coupling portion is coupled to the first coupling portion, an outer side surface of the second coupling body.

12 . A supporting device for supporting a display, comprising:

a stand base including a first coupling portion, and the first coupling portion including a first coupling body formed in a hollow shape, and a coupling hole formed in the first coupling body; and

a stand neck including a second coupling portion couplable with the first coupling portion, and the second coupling portion including:

a second coupling body that is insertable into the first coupling body,

a spring accommodated inside the second coupling body, and

an elastic block that is movable relative to the second coupling body by the spring and is engageable with the coupling hole, wherein
