PROBLEM TO BE SOLVED: To provide a flat display panel capable of not only improving a visual angle difference due to a difference between the positions of a viewer and a screen by curving the screen of the flat display panel but also greatly improving the realism, in particular capable of allowing change in a curvature of a concave surface liquid crystal panel, forming the concave surface liquid crystal panel into a paraboloid, and adjusting the shape of the paraboloid according to a distance between the viewer and the concave surface liquid crystal TV image screen, thereby greatly improving realism given to the viewer. SOLUTION: Flat display panel curvature-varying devices are arranged in four corners and two positions in the upper and lower parts in the longitudinal axis direction center of the flat display panel. By means of the flat display panel curvature-varying devices, the positions of the four corners and the two positions in the upper and lower parts in the longitudinal axis direction center of the flat display panel are adjusted independently, and consequently a curvature of the flat display panel can be adjusted.
