Display device

The invention provides a display device and a screen splitting method of the display device, and relates to the technical field of display. The display device is provided with a plurality of curved-surface display areas, the curved-surface display areas are spliced into a special-shaped display area, and each curved-surface display area comprises a plurality of spliced display units. Each display unit is of a triangular structure, the curvature radiuses of the display units in the curved surface display areas are equal, each curved surface display area is provided with a plurality of vertexes, and a regular polygon can be defined by the vertexes. In the embodiment of the invention, a group of display units are spliced to form the curved-surface display area, and then a plurality of curved-surface display areas are spliced to form the special-shaped display area, so that the display of a special-shaped picture is realized, the picture display effect is improved, and a user has a better immersion feeling; in addition, the display units are all arranged to be of a triangular structure, so that the number of types of the display units is reduced, the mold opening cost of the display units is conveniently reduced, and the process difficulty of the display device is reduced.
