Patent ID: 7187422

Claim:
A device comprising an active plate including pixel electrodes and associated address lines formed from a transparent conductive material, manufactured by a process comprising: providing a transparent conductive material layer and a metal layer in succession over a substrate; depositing and patterning a shielding layer into a configuration corresponding to the desired pattern of the transparent conductive layer required for the pixel electrodes and the address lines, the shielding layer being formed in a manner such that an etching property of the shielding layer at regions corresponding to the pixel electrodes differs from that at the regions corresponding to the address lines; subjecting the shielding layer to an etching process using the difference in properties so as to remove the regions of the shielding layer corresponding to the pixel electrodes while leaving portions of the shielding layer at the regions corresponding to the address lines; and thereafter removing the portions of the metal layer at the regions corresponding to the pixel electrodes.
