Abstract: A display device with a adjustable curvature is described. The display device includes a display module, a base body, a fixing portion, and two adjusting portions. The fixing portion is configured to fasten the display module to a center of the base body. The two adjusting portions symmetrically disposed on two sides of a back portion of the display module respectively so that the ejector pin moves toward the display module 101 and the display module 101 relative to the intermediate region of the side regions moves forward, thereby forming a curved surface module. The present invention provides a curved television for appropriately adjusting the curvature of the display module at the time of viewing, so as to obtain a better display effect.
