Abstract
A method for manufacturing a liquid crystal lens includes: patterning an insulating layer into a plurality of insulating regions spaced apart from each other on a substrate using a first photo mask; depositing a conductive layer on the insulating layer; applying a first, negative photoresist onto the conductive layer; exposing the first photoresist using a second photo mask in which first regions of the first photoresist corresponding to portions between adjacent insulating regions are opened; exposing the first photoresist using a third photo mask in which second regions corresponding to tops of the plurality of insulating regions are opened; and etching the conductive layer using the first photoresist.
