DISPLAY DEVICE

摘要

A display device that includes: a light source that emits a visible light and a detection light having a wavelength range different from a wavelength range of the visible light; an optical member disposed on the light source; a display panel disposed on the optical member and including a pixel configured to receive the visible light to generate an image; a liquid crystal lens that includes a liquid crystal layer and first electrodes, wherein the first electrodes form a first lens unit, the first lens unit having a first focal point located in the optical member to condense the detection light exiting from the display panel to an input device disposed outside the display panel; and a light sensor that receives the detection light reflected by the input device to sense an external input.
