Abstract:
A method for fabricating a protrusion in a fabricating process of a liquid crystal display, comprising steps of:providing a substrate being pervious to light and having a first thickness; forming a photoresist layer having a second thickness on a first surface of said substrate; providing a photomask over a second surface of said substrate; performing a first exposure with a first exposing light on said photoresist layer with said photomask serving as a mask, wherein a first incident angle of said first exposing light is greater than zero degree; performing a second exposure with a second exposing light on said photoresist layer with said photomask serving as a mask, wherein a second incident angle of said second exposing light is greater than zero degree; and performing a development on said photoresist layer to remove a portion of said photoresist layer and form said protrusion on said first surface of said substrate.
