Abstract
A liquid crystal lens including a plurality of electrodes and a substrate is provided. A plurality of parallel electric fields is formed by controlling the potentials of the electrodes, so as to speed up the mechanism for toppling the liquid crystal molecules. In other words, the liquid crystal lens has a high respond time. In addition, a plurality of active devices is disposed at the sides of the electrodes in the liquid crystal lens, in which the active devices are electrically connected to the electrodes. When the active devices are driven, a current is formed on the electrodes, so as to raise the temperature of the liquid crystal lens. Accordingly, the liquid crystal lens can be operated in a low temperature environment.
