Abstract:
A liquid crystal display apparatus, comprising:plural main scan wiring lines; signal wiring lines arranged so as to intersect with the plural main scan wiring lines; a display matrix having one or more sub scan wiring lines arranged along the plural signal wiring lines; plural pixels arranged in a column direction in an area partitioned by the main scan wiring lines and the signal wiring lines, the plural pixels being formed with plural pixel TFT devices; and a display electrode; wherein one end of a main circuit of the plural pixel TFT devices is connected to a display electrode in a corresponding pixel, and its other end is connected to a signal wiring line; wherein at least one of the gate electrodes of the plural pixel TFT devices is connected to a main scan wiring line, and the remaining gate electrodes are connected to an identical sub scan wiring line in a row direction; and wherein the liquid crystal apparatus further comprises: a main scan circuit for selecting and driving sequentially the main scan wiring lines, and a sub scan circuit for driving the sub scan wiring line; a signal circuit for supplying an image signal to the signal wiring lines in synchronization with a main scan signal and a sub scan signal; and an opposed substrate power circuit for applying a voltage to an opposed electrode facing plural display electrodes and supporting a liquid crystal; wherein a pair of TFT devices are connected to a signal wiring line and a display electrode by a series connection, and one of the gate electrodes of the pair of TFT devices is connected to a main scan wiring line assigned to every two pixels in a row direction, and the other gate electrode thereof is connected to the sub scan wiring line assigned to a single signal wiring line; and wherein a row of pixels are selected and driven in response to a main scan signal and a sub scan signal.
