Liquid crystal lens panel, method of manufacturing the same and display device having the liquid crystal lens panel
View Patent ↗A liquid crystal lens panel includes a first substrate, a second substrate, a liquid crystal layer and a light-blocking member. The first substrate includes a plurality of individual electrodes. The individual electrode receives a voltage to have a light path length distribution of a Fresnel lens shape.
