Abstract:
A method of fabricating a liquid crystal display, comprising the steps of:forming a plurality of gate lines adjacent a front side of a substrate; forming a plurality of data lines over said plurality of gate lines, wherein said gate lines cross said data lines to define a plurality of pixel cells; forming a plurality of auxiliary electrodes over said plurality of gate lines; forming a switching device for each pixel at an intersection of a gate line and a data line, wherein each switching device includes an electrode; depositing a protection layer over said switching devices, over said data lines, and over said pixel cells; photolithographically forming contact holes through said protection layer to expose portions of said switching device electrodes; forming a transparent conductive layer over said protection layer and over said exposed portions of said switching devices; forming a negative type photoresist layer on said transparent conductive layer; first, exposing a first portion of said negative type photoresist layer by passing light at an angle through a back-side of said substrate to dispose the first portion at a predetermined distance from at least one side of the data line; second, exposing a second portion of said negative type photoresist layer using light passed through mask over said front side, the second portion including a part of region on the gate line; forming a photoresist pattern by developing said exposed negative type photoresist layer; and etching said transparent conductive layer using said photoresist pattern as an etch mask.
