摘要： The present disclosure provides a buffer structure and a display device. The buffer structure includes a deformable sealed capsule, and a flowable filler in a hollow part of the sealed capsule. For the buffer structure according to the present disclosure, the hollow part of the deformable sealed capsule is provided with the flowable filler, when the display device suffers uneven internal forces resulting from deformation of the liquid crystal panel or the backboard, the flowable filler in the hollow part of the buffer structure flows to a position suffering a smaller force from a position suffering a larger force until achieving the force balance, thereby to reduce difference of forces at different positions in the display device and further improve light leakage phenomenon caused by uneven forces.
