摘要： A gate drive circuit includes plural stages connected together one after each other. Each of the plural stages includes a circuit transistor, a capacitor part, a first connection part and a second connection part. The circuit transistor outputs the gate signal through a source electrode in response to a control signal applied through a gate electrode. The capacitor part includes a first electrode, a second electrode formed on the first electrode, and a third electrode formed on the second electrode. The first connection part electrically connects the gate electrode of the circuit transistor and the second electrode of the capacitor part.

摘要： A touch sensor is installed inside a liquid crystal display panel to sense a touch operation and includes a light sensing part including a photodiode, a capacitance sensing part including a liquid crystal capacitor, and a sensing signal output part. The light sensing part generates a control signal corresponding to a variation in the amount of external light when the liquid crystal display panel is touched. The capacitance sensing part varies the control signal based on a variation in the capacitance of the liquid crystal capacitor when the liquid crystal display panel is touched. The sensing signal output part generates a sensing signal in response to the control signal and determines an output timing of the sensing signal.
