Publication number: 20090206051Abstract: A capacitive substrate and method of making same in which first and second glass layers are used. A first conductor is formed on a first of the glass layers and a capacitive dielectric material is positioned over the conductor. The second conductor is then positioned on the capacitive dielectric and the second glass layer positioned over the second conductor. Conductive thru-holes are formed to couple to the first and second conductors, respectively, such that the conductors and capacitive dielectric material form a capacitor when the capacitive substrate is in operation.Type: ApplicationFiled: March 2, 2009Publication date: August 20, 2009Inventors: Rabindra N. Das, Frank D. Egitto, John M. Lauffer, How T. Lin, Voya R. Markovich

Publication number: 20090180062Abstract: A display substrate in accordance with one or more embodiments includes a first line pattern, a first insulation layer, a second line pattern, a color filter layer and a pixel electrode, which are formed on a substrate. The first line pattern includes a gate line and a light-blocking layer. The light-blocking layer has a first opening portion formed in a storage capacitor region. The first insulation layer is formed on the substrate having the first line pattern. The second line pattern is formed on the first insulation layer. The color filter layer is formed on the substrate having the second line pattern, and has a second opening portion overlapping with the storage electrode. The pixel electrode is formed on the substrate having the color filter layer. Thus, short circuits between the storage electrode and the pixel electrode may be prevented.Type: ApplicationFiled: August 6, 2008Publication date: July 16, 2009Inventor: In-Woo KIM
