  In Patent Document 1, a display mounting member on which a display unit of a display device is mounted is horizontally mounted on a stand column erected on a support base, and a tilt mechanism is provided on the display mounting unit, so that the posture of the display unit can be arbitrarily set. There has been proposed a display device including a support device that can be held at a certain angle. In this case, by further connecting the stand column and the display mounting portion in an electrically insulated state, the support device does not resonate with respect to the specific frequency of the electromagnetic wave emitted from the display portion, and radiation interference is reduced.

In Patent Document 2, a case that constitutes an outer shell design of a stand, and a movable member that has an end abutting against the installation surface of the flat display device to support the inclination of the case, and can extend out of the case and be retracted into the case There has been proposed a stand for a flat display device, which includes an angle adjustment mechanism having a fixing mechanism and a fixing mechanism for fixing the angle adjustment mechanism to a case, and can adjust the inclination angle of the display surface of the flat display device.

On the back surface of the liquid crystal display 1, a support member 10 having a substantially cross-sectional side cross section that supports the liquid crystal display 1 in a state where the liquid crystal display 1 is tilted within a certain range. It is fixed with a screw 19 in a state where it is in contact with.

  The support member 10 is a synthetic resin member obtained by bending a substantially rectangular plate body in a long side direction and a short side direction into a substantially partial spherical shell shape, and a curved convex surface 13 having a smooth three-dimensional curved surface on one side. It is curved to make. The support member 10 is fixed to the back surface of the liquid crystal display 1 with the long side direction up and down, and two ends are extended along the longitudinal direction of the support member 10 on the short side portion on one side. Two leg portions 11 and 11 are formed. Further, a substantially rectangular through hole is formed on the other side of the support member 10 along the edge of the short side, and the through hole is used as the handle portion 12. A through hole 14 that is long in the longitudinal direction of the support member 10 is formed in a substantially central portion of the support member 10, and two guide holes 15 and 15 that are long in the longitudinal direction are formed on both sides of the through hole 14. 14 is formed substantially in parallel.

The curved concave surface 3 has a curvature substantially equal to the curved convex surface 13 of the support member 10, and a screw hole 4 that is screwed into the screw 19 is formed at the center of the curved concave surface 3. Guide pins 5 and 5, which are columnar protrusions, are provided on the left and right sides, respectively. The distance between the screw hole 4 and the guide pins 5 and 5 is substantially equal to the distance between the through hole 14 of the support member 10 and the guide holes 15 and 15.

  When the support member 10 is fixed to the back surface of the liquid crystal display 1, the shaft portion of the screw 19 is inserted into the through hole of the support member 10 with the curved convex surface 13 of the support member 10 in contact with the curved concave surface 3 of the liquid crystal display 1. 14 is inserted and fixed to the screw hole 4 of the liquid crystal display 1 by screwing.
