Patent ID: 7145620

Claim:
A thin film transistor array panel for a liquid crystal display, comprising: a substrate; a plurality of signal lines including a gate line and a data line insulated from each other, the plurality of signal lines being provided on the substrate; a switching element electrically connected to the gate line and the data line; a pixel electrode electrically connected to the switching element and overlapping at least one of the signal lines to form at least one overlapping area, wherein the pixel electrode includes an expansion positioned at a corner thereof, the expansion forming a portion of the at least one overlapping area, wherein the portion of the at least one overlapping area including the expansion proceeds more deeply over the at least one signal line than the remaining portion of the at least one overlapping area, and a depth of the expansion over the at least one signal line is such that the expansion does not cover an entire width of the at least one signal line; an alignment layer covering the pixel electrode, wherein the expansion is disposed proximal to a starting position of a rubbing action of the alignment layer; and a storage electrode provided on the substrate, wherein the storage electrode overlaps the pixel electrode for forming a storage capacitance with the pixel electrode.
