1. A display device, comprising:
a display panel, configured to display an image; a slit grating, on a light exiting side of the display panel; and a liquid crystal lens, on a light exiting side of the slit grating to realize three effects of a concave lens effect, a convex lens effect and a flat light-transmitting glass effect; wherein the liquid crystal lens realizes the concave lens effect in a condition that the display device is in a double vision display, directs a first image and a second image emitted from the display panel and passing through the slit grating to a first viewing region and a second viewing region respectively; the liquid crystal lens realizes the flat light-transmitting glass effect in a condition that the display device is in a 3D display, transmits a left eye image and a right eye image split by the slit grating.
