For example, the first and second projectors 400a and 400b may be formed of a metal material having an elastic modulus of about 150 MPa or more.

This is because when the elastic modulus of the first and second fixtures 400a and 400b is about 150 MPa or less, the weight can be broken by the weight and external force of the display device.

For example, the first and second fictitious parts 400a and 400b may be formed of an aluminum-coated steel plate AL, a stainless steel plate SUS, an aluminum-stainless steel plate AL-SUS, a chromium- , An electro galvanized steel sheet (EGI), a hot-dip galvanized steel sheet (GI), a cold-rolled zinc sheet (SPCC), and an electro-tinned steel sheet (SPTE).

Then, the thickness t of the first and second fictitious parts 400a and 400b may be about 0.8 to 6 mm.

The reason is that if the thickness t of the first and second fictitious parts 400a and 400b is about 0.8 mm or less, the supporting force is lowered and the rigidity of the connection area between the supporter and the base may be lowered, If the thickness t of the two projectors 400a and 400b is about 6 mm or more, the overall thickness and area of the stand become large, which may adversely affect the slimness of the stand.

The first area 400a of the first fixture 400a is in contact with the lower surface of the first supporter and the second area 402 of the first fixture 400a is in contact with the lower surface of the first end of the base 400a Can be contacted.

The first area 401 of the second pick 400b is in contact with the lower surface of the second supporter and the second area 402 of the second pick 400b is in contact with the lower surface of the second end of the base Can be contacted.
