Abstract:
1. A liquid crystal lens, comprising: a first substrate; a second substrate disposed facing the first substrate and separated from the first substrate by a predetermined distance; a first electrode on an inner surface of the first substrate; a first alignment layer directly on the first electrode; a single second electrode on an inner surface of the second substrate, the single second electrode including a first opening that has a first width; an insulating layer directly on the single second electrode; a single third electrode formed as a single layer directly on the insulating layer, the single third electrode including a second opening that has a second width; a second alignment layer directly on the third electrode; and a liquid crystal layer disposed between the first and second alignment layers, wherein the single second electrode and the single third electrode have a same bar shape and entirely overlap with each other, and wherein a single liquid crystal lens is formed by the first electrode, the single second electrode including the first opening and the single third electrode including the second opening, and does not include any other electrode.
