Abstract
An LCD device and method of forming the same includes a transparent insulation substrate, a plurality of scan lines and data lines perpendicularly crossing each other on the substrate, a metal segment layer overlapping the scan line, a pixel electrode formed at the area surrounded by two neighboring scan lines and two neighboring data lines for contacting with the metal segment, and a switching element electrically connected with the pixel electrode, the scan line and the data line. The pixel electrode or the metal segment layer has at least one small width projecting portion for allowing contact between the metal segment layer and the pixel electrode through a contact hole.

A method of forming a liquid crystal display, comprising:
- forming at least first and second scan lines on a substrate, the first scan line having a first projecting portion, which projects towards the second scan line;
- forming an insulation layer over the substrate;
- forming a transistor such that the first projecting portion forms part of the transistor;
- forming a metal segment layer over a portion of the second scan line;
- and
- forming a pixel electrode between the first and second scan lines such that a first end of the pixel electrode is connected to the transistor and a second end of the pixel electrode, opposite the first end, includes at least one second projecting portion projecting over and in contact with the metal segment layer, the second projecting portion having a width less than one-half a width of the pixel electrode, and non-projecting portions of the second end partially covering the metal segment layer.
