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 ad
