Appeal 2007-0037
Application 10/032,056
BACKGROUND
The claims are directed to a liquid crystal display device wherein the
entire surface of the data lines, which are made from a transparent
conductive material such as indium tin oxide (ITO), are covered with an
additional metal of low resistance such as aluminum.
Claim 1 is illustrative:
1. An array substrate for a liquid crystal display device, comprising:
a substrate;
a plurality of gate lines arranged transversely on the substrate;
a plurality of data lines disposed orthogonal to the plurality of
gate lines;
a plurality of thin film transistors formed on the substrate
adjacent to intersections of the gate lines and the data lines, each thin
film transistor including a gate electrode, a gate insulation layer, an
active layer, an ohmic contact layer, a source electrode, and a drain
electrode;
a plurality of pixel electrodes disposed at pixel regions defined
by the intersections of the gate lines and the data lines, each pixel
electrode connected to a corresponding one of the drain electrodes;
and
a metal layer formed on an entire surface of each of the data
lines and at peripheral portions of the drain electrode,
wherein the drain electrode and the pixel electrode are formed
from the same material.
