Abstract
A near-eye display device including a display panel, a liquid crystal layer, and a lens element is provided. The liquid crystal layer is disposed adjacent to the display panel and disposed between the display panel and the lens element. The display panel is configured to provide an image light beam to pass through the liquid crystal layer. At least a portion of the liquid crystal layer is configured to modulate the image light beam according to the phase modulation. Phase modulation occurs to at least a portion of the liquid crystal layer to modulate the image light beam, and the lens element is a micro lens array.
