The invention provides a display panel component, a peep prevention structure and a production method thereof and belongs to the technical field of peep prevention with an aim to solve problems that apeep prevention angle is fixed and cannot be controlled in the prior art. The peep prevention structure is characterized in that the difference between the refractive index of a second material and that of a first material is controlled through a refractive index control unit, photonic crystal effect between the a first substrate and the second material is changed, and light dipping angle is controlled. By the adoption of a display panel with the peep prevention structure, the viewing angle of a light dipping surface can be controlled to change within the range of +/-5-+/-90 degrees.
