1. A liquid lens comprising:
a first plate having a cavity for receiving a first liquid and a second liquid;
a first electrode disposed on a first surface of the first plate;
a second electrode disposed on a second surface of the first plate facing the first surface; and
a temperature device disposed on the first surface of the first plate to be spaced apart from the first electrode;
wherein the first electrode includes first to eighth individual electrodes sequentially arranged along a circumferential direction about an optical axis,
wherein the first surface of the first plate includes:
a first region and a second region disposed facing each other in a first horizontal direction with respect to a center of the cavity, and
a third region and a fourth region disposed between the first region and the second region and facing each other in a second horizontal direction perpendicular to the first horizontal direction with respect to the center of the cavity,
wherein the temperature device includes a temperature sensor group and a heater group disposed between at least two of the first to eighth individual electrodes,
wherein the temperature sensor group includes a first temperature sensor disposed in the first region and a second temperature sensor disposed in the second region,
wherein the heater group includes a first heater disposed in the third region and a second heater disposed in the fourth region,
