shielding member also overlaps the metal thin film upper electrode of the
charging device. As a result, light is blocked from the metal thin films of the
switching device and charging device thus preventing undesired reflections that
would otherwise degrade image quality.
Representative claim 1 is reproduced as follows:
A liquid crystal display device comprising:
a pixel electrode at a pixel area between a gate line and a data line;
a switching device at an intersection between the gate line and the data
line, the switching device comprising a light-shielding member overlapping the
switching device and extending from an end at the pixel electrode side of a metal
thin film provided within the switching device into the pixel area, the light
shielding member covering and extending past all sides of the metal thin film with
a margin sufficient to block light incident on the metal thin film, wherein the
switching device is a thin film transistor at the intersection between the gate line
and the data line for driving the pixel electrode, and wherein the metal thin film of
the switching device is a drain electrode connected to the pixel electrode.

35 U.S.C. § 103(a) as being unpatentable over the admitted prior art in view of
Murade.
