Manufacturing method of liquid crystal cell

Abstract

A manufacturing method of a liquid crystal cell includes providing a first substrate having a first surface and a second surface opposite to the first substrate; providing a second substrate having a third surface and a fourth surface opposite to the third substrate; etching the first surface of the first substrate to form a plurality of first support pillars; filling liquid crystals into a gap between the first substrate and the second substrate to form a liquid crystal layer; and bonding the first substrate and the second substrate and causing the first surface of the first substrate and the third surface of the second substrate to face each other.
