Abstract
(EN)
The present invention provides a liquid lens comprising: a first plate which accommodates a conductive liquid and a non-conductive liquid, has an opening having a predetermined inclined surface, and is formed from silicon; a first electrode disposed on the first plate; a second electrode disposed below the first plate; a second plate disposed on the first plate; a third plate disposed below the first plate; and a light shielding layer which is disposed on or below the first plate and limits the amount of light passing through the opening area.
