Patent ID: 7947984

Claim:
A liquid crystal display (LCD) device, comprising: a signal controller for outputting first and second control signals Q and /Q; a pull-up transistor between a clock signal terminal CLK and a gate driving signal output terminal for receiving the first control signal Q, the pull-up transistor having a gate electrode, a source electrode and a drain electrode, wherein the pull-up transistor has an asymmetric structure in a first area of the source electrode overlapped with the gate electrode and a second area of the drain electrode overlapped with the gate electrode so that a first capacitor overlapping the gate electrode with the source electrode is different from a second capacitor overlapping the gate electrode with the drain electrode; and a pull-down transistor connected between the gate driving signal output terminal and a ground voltage terminal, wherein the pull-down transistor receives the second control signal, wherein each of the source and drain electrodes has a single layer.
