1. A display device comprising:
a display panel having a curved shape in a cross-section along one axis, the display panel including a display screen that includes a concave curved surface; and
an illumination section provided in at least part of a peripheral region of the display screen of the display panel, the illumination section including a light guide plate that extends along the peripheral region and at least one LED light positioned at a first end of the light guide plate to emit light into the light guide plate so as to control and change brightness to adjust visual effects associated with the curved shape, and
a frame member supporting the display panel comprising parallel first support members running along the one axis and more than two spaced apart second support members running along another axis, perpendicular to the one axis, that extends to the first support members,
in which a radius of curvature (R) of the concave curved surface of the display screen is constant such that the radius of curvature (R) has a single value for the display screen in its entirety and in which the single value is at least 6000 mm and does not exceed 8000 mm.
