Disclosed is a structure of an extending-type display screen. A hollowed-out part is arranged on at least one side of a main base, and two guide assemblies are symmetrically arranged at positions, along two sides of the hollowed-out part, inside the main base; at least one driving assembly is assembled in the main base, and the driving assembly is provided with a power source, by means of which the driving assembly can be driven to move along the guide assemblies; and at least one side of a flexible screen is wound around the outer periphery of at least one rotating shaft, and the rotating shaft is rotatably arranged on a side of the driving assembly and forms a linkage together with same. The driving assembly is used to link the rotating shaft to move towards the outside of the main base and along the guide assemblies, so that the flexible screen can be gradually released and unfolded outwards from the outer periphery of the rotating shaft, and conversely, the driving assembly is used to link the rotating shaft to gradually move into the main base, and the flexible screen is rolled up by means of the rotating shaft.
