Abstract
Disclosed are a liquid lens and a liquid lens module, which enhance the fill factor of a liquid lens having an inclined partition, thereby achieving a low drive voltage and a high fill factor. The liquid lens includes an oil layer and a conductive liquid inside a chamber having an inclined partition. The oil layer is formed of an oil mixture obtained by mixing at least two types of oils having different indices of refraction, and the oil mixture has the index of refraction corresponding to the index of refraction of the material in which the chamber is formed.
