DISPLAY DEVICE

WIPO Patent Application WO/2020/215184

A1

A display device (100, 200), comprising a display layer (110, 210) and a lens layer (120, 220). The lens layer (120, 220) is provided at the light exit side of the display layer (110, 210), and comprises at least one grating compound lens unit (121, 221); the display layer (110, 210) comprises at least one display pixel set (111, 211), and the display pixel set (111, 211) is configured to emit light used for imaging toward the grating compound lens unit (121, 221) during a display process; the grating compound lens unit (121, 221) is configured to perform optical imaging on the display pixel set (111, 211); and the grating compound lens unit (121, 221) is further configured to deflect the light used for imaging so that the image side center field direction of the grating compound lens unit (121, 221) intersects with the extending direction of the optical axis of the grating compound lens unit (121, 221), which thus enables the display device (100, 200) to have one or more viewpoints. The imaging quality of the lens layer to the display layer may be improved.
