Abstract:
A thin film transistor liquid crystal display comprising:a transparent insulating substrate;a plurality of gate lines and data lines arranged on the transparent insulating substrate perpendicular to each other, wherein at least one of the gate lines comprises a recess at a portion toward a corresponding pixel area;a pixel electrode disposed within the pixel area defined by a pair of the gate lines and a pair of the data lines, wherein the pixel electrode comprises a protrusion disposed within the recess without contacting a corresponding one of the gate lines;a thin film transistor disposed at a portion of an intersection of the corresponding one of the gate lines and a corresponding one of the data lines, wherein the thin film transistor comprises a gate electrode including the recess; the protrusion of the pixel electrode functioning as a source electrode; a first ohmic contact layer, a semiconductor layer and a second ohmic contact layer all stacked on the protrusion; and a drain electrode withdrawn from the corresponding one of the data lines and disposed on the second ohmic contact layer, wherein channel regions in the semiconductor layer are formed in a vertical direction at each portion adjacent to the gate electrode; andstorage lines arranged perpendicular to the gate lines and separated from the data lines.
