Abstract: Aspects of the invention can provide an electro-optical device having n image signal lines to which n serial to parallel converted image signals are supplied. A driving circuit has a sampling circuit that can include a plurality of thin film transistors. Each of the thin film transistors can have (i) a drain connected to a drain wiring line arranged from a data line in a direction in which the data line extends, (ii) a source connected to a source wiring line arranged from the image signal line in a direction in which the data line extends, and (iii) a gate arranged to be sandwiched between the drain wiring line and the source wiring line in a direction in which the data line extends, and the plurality of thin film transistors can be arranged to correspond to the plurality of data lines.

Abstract: An electro-optical device copes with a decreased size of a pixel pitch by using a comparatively simple configuration in which a driving circuit system is formed on one substrate. In a scanning-line driving circuit, each transfer signal of a shift register is branched off into three signal components, and an enable circuit is provided for each signal component. During a pulse cycle of the transfer signal, one transfer signal is divided into three components while being sequentially shifted in the time domain in accordance with enable signals whose phases are sequentially shifted from each other, and the divided components are output as scanning signals. The same applies to a data-line driving circuit.

Abstract: In an electro-optical apparatus, such as a liquid-crystal apparatus, a TFT array substrate is provided with pixel electrodes and TFTs connected thereto. In addition, a peripheral area (including a frame area and a sealing area) is provided with peripheral circuits that drive the pixel electrodes, such as data-line driving circuits and a sampling circuit, and wires that send image signals. On an opposite substrate, an opposite electrode is formed so as to avoid areas opposite the wires. Therefore, with a relatively simple structure, parasitic capacitors generated between the wires on one substrate and the opposite electrode on the other substrate are reduced, and high-quality image display having a reduced ghost is achieved.

On an opposite substrate (20), an opposite electrode (21) is formed so as to avoid areas opposite the wires.

Abstract: A circuit for driving an active matrix liquid crystal display having M rows and N columns by video digital data of K bits is provided. The rows and columns intersect at a plurality of thin film transistors which form at least in part a pixel at each intersection of a column and row. An analog switch capable of ON and OFF state receives a video voltage and a control signal and selectively outputs the video voltage to each column in response to a control signal. The video voltage varies in level sequentially increasing from the OFF state at least once each horizontal scanning period. A control receives the K bit digital input data and produces a control signal for controlling the time of the ON state of the analog switch in response to the input data. K is an integer at least equal to 1.

The rows and columns intersect at a plurality of thin film transistors which form at least in part a pixel at each intersection of a column and row. An analog switch capable of ON and OFF state receives a video voltage, a discharge power supply voltage and a control signal and selectively outputs either the video voltage and the discharge power supply voltage to each column in response to a control signal. The video voltage varies in level sequentially increasing from the OFF state at least once each horizontal scanning period. A control receives the K bit digital input data and produces a control signal for controlling the time of the ON state of the analog switch in response to the input data.
