The present disclosure relates to a display device. A downward-bending portion is formed on an end of an inner plate arranged on the inner surface of a back cover, which is a back support structure of the display device, such that the outer surface of the downward-bending portion contacts the inner surface of the back cover, thereby improving the rigidity and heat-radiating performance of the inner plate, and guaranteeing that the elastic force from the downward-bending portion prevents the display panel from being damaged by cracks. Furthermore, an inward-bending portion is formed on the front end of the vertical extension portion of the back cover, thereby improving the rigidity of the back cover, and guaranteeing that elastic deformation of the inward-bending portion protects the display device from lateral impacts.
