At present, a peep-proof light-emitting element can be arranged in a non-sub-pixel area, and the emitting direction of light rays emitted by the peep-proof light-emitting element from the light emitting side of the display panel corresponds to the display direction of the large visual angle of the display panel, so that a picture displayed by the display panel cannot be clearly watched from the large visual angle, the display visual angle of the display panel is further reduced, and peep-proof is realized. However, the light output rate of the light emitted by the peep-proof light emitting element is low, that is, the loss of the light emitted by the peep-proof light emitting element on the display panel is large, so that the peep-proof effect is poor.

Referring to fig. 5, fig. 5 is a schematic view of a second layer structure of a peep-proof sub-pixel area of a display panel according to a second embodiment of the application.
