Abstract:
Provided are liquid crystal glasses and display panel having light leakage elimination element. Glasses includes: opposite first and second substrates; first electrode on side of first substrate facing second substrate; second electrode on side of second substrate facing first substrate and on side of first electrode distal to first substrate; liquid crystal layer between first and second electrodes; lens unit including valid and invalid areas, one of which converges to collimated light by refraction and the other diverges parallel light through refraction; light leakage elimination element between second electrode and lens unit, including wire grid polarizer and half-wave plate sequentially away from the second electrode, orthographic projections of light leakage elimination element and invalid area on second substrate at least partially overlapping; light blocking element on side of liquid crystal layer distal to second electrode and prevents light passing through light leakage elimination element and invalid area from exiting glasses.
