Patent ID: 7826021

Claim:
A method of manufacturing a substrate for a liquid crystal display, the method comprising: forming a plurality of first line-shaped fine grooves parallel to each other in a lengthwise direction and a plurality of second line-shaped fine grooves parallel to each other in a width direction on the substrate; forming an inorganic insulating film on the substrate including the first and second line-shaped fine grooves; forming a plurality of gate lines within the first line-shaped fine grooves; forming a plurality of data lines that contacts an upper surface of the inorganic insulating film within the second line-shaped fine grooves; and forming a passivation layer on the substrate including the data lines, wherein each gate line is extended to a first portion higher than a surface of the substrate, and is formed to contact an entirety of a top surface and a sidewall surface within the corresponding first line-shaped fine groove, wherein each data line is extended to a second portion higher than a surface of the inorganic insulating film, and wherein the first line-shaped fine grooves on which the gate lines are formed and the second line-shaped fine grooves on which the data lines are formed are separately formed in the substrate.
