    摘要: A thin film transistor liquid crystal display according to the present invention provides against cut-off of lines for supplying a predetermined ‘ON’- or ‘OFF’-signal to thin film transistors and improves ‘ON’-current characteristic of the thin film transistors arranged in parallel. The thin film transistor liquid crystal display comprises primary lines and secondary lines to supply scanning signals and data signals respectively wherein each of said primary and secondary lines are branched and a thin film transistor is electrically coupled to each of the branched lines such that at least two transistors are turned on and off simultaneously when one of primary lines and one of secondary lines are applied with scanning signals and data signals respectively. Particularly, the primary and secondary lines are patterned in a trapezoid shape to define a lattice having two vertical sides and two horizontal sides for a unit pixel electrode.
