Abstract
A display device is provided, including a display panel; a controller; and an auxiliary panel disposed at a light emitting side of the display panel, the auxiliary panel including a first liquid crystal layer, a first substrate and a second substrate, the first liquid crystal layer being encapsulated between the first substrate and the second substrate, the first substrate including a first base substrate and a first transparent electrode layer, and the second substrate including a second base substrate and a second transparent electrode layer, wherein the controller is configured to provide a control signal to the first and second transparent electrode layers to cause different regions of the first liquid crystal layer to have different refractive indices, such that light transmitted from the display panel forms an image on a curved surface having an opening facing the light emitting direction of the display device.
