    Abstract: An optical structure, a display device and an operating method thereof are provided. The optical structure includes: first electrode and second electrode arranged opposite to each other; first alignment layer; second alignment layer; liquid crystal molecules arranged between first alignment layer and second alignment layer; and insulative protrusions arranged at a side of first alignment layer facing second alignment layer. The insulative protrusions are spaced apart from and arranged parallel to each other, and the protrusion has a same refractive index as the liquid crystal molecules in energized or de-energized state. Through controlling electric signals applied to first electrode and second electrode, it is able to switch the optical structure between first state where the optical structure does not change propagation direction of light entering the optical structure and second state where the optical structure is capable of changing propagation direction of light entering the optical structure.
