摘要：
A liquid crystal lens comprises a first liquid crystal lens part. The first liquid crystal part comprises first and second flat parallel substrates and a liquid crystal filled between said first and second light-transmitting regions. First and second electrodes are provided on said first and second substrates, respectively, to apply a voltage across the first liquid crystal. An electric heating element is provided on said first substrate to heat said first liquid crystal.
