The invention discloses a display having a curved-surface display function. The display comprises a flat-panel screen, an image picking-up module, an eyeball tracking module, a screen rotating and tipping module, a plane-surface-to-curved-surface simulation module and a plane-surface-to-curved-surface mechanism module. According to the display, a first plane image displayed in the flat-panel screen is converted into a second plane image by virtue of the plane-surface-to-curved-surface simulation module according to positions of user's eyes, wherein the first plane image is a square plane image, and the second plane image is a pillow-shaped plane image, so that a user can feel a visual effect similar to that of a curved-surface image; therefore, a simulated curved-surface image is actively provided according to the positions of the user's eyes, so that a visual viewing effect is enhanced; in addition, the flat-panel screen is bent as a curved-surface screen by virtue of the plane-surface-to-curved-surface mechanism module according to the positions of the user's eyes, so that a plane image displayed in the flat-panel screen is bent as a curved-surface image; therefore, an actual curved-surface image is actively provided according to the positions of the user's eyes, so that a visual viewing effect is enhanced.
