Abstract:
1. A liquid crystal lens apparatus comprising a first liquid crystal lens unit comprising: a first substrate having a first and a second opposing surfaces and including a first transparent region; a second substrate having a first and a second opposing surfaces and including a second transparent region aligned in parallel with the first transparent region of the first substrate, the first surface of the first substrate being opposite to the first surface of the second substrate; a first liquid crystal layer comprising liquid crystal filled between the first surfaces of the first and second transparent regions; and first and second electrodes arranged on the first and second substrates, respectively, to apply a voltage across the first liquid crystal layer; an electric heating element arranged to heat the first liquid crystal layer; and at least one thermo-transmission member ineffective in self-heating but made of a material storable of thermal energy from outside and radiant of the stored thermal energy, the at least one thermo-transmission member being so shaped and positioned as to receive heat energy from the electric heating element and radiate the stored heat energy to facilitate heating of the liquid crystal layer by the electric heating element.
