摘要： The invention provides an electro-optical device that can include a pixel electrode, a thin-film transistor (TFT) including a semiconductor layer connected to the pixel electrode, and a data line and scanning line connected to the TFT. The scanning line can include a narrow part as a gate electrode facing a channel region in the semiconductor layer, and a wide part not facing the channel region.Such construction permits the electro-optical device to display high quality images by preventing light from impinging the TFT.

摘要： 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. Two adjacent thin film transistors with the boundary between thin film transistor groups interposed therebetween among the plurality of thin film transistors can be arranged such that the arrangements of the source and drain wiring lines with a gate interposed therebetween are opposite to each other. By doing so, it is possible to reduce image faults caused by parasitic capacitance located between the thin film transistors in the sampling circuit.

摘要： Aspects of the invention provide an electro-optical device that can include data lines that are a built-in light shielding film, scanning lines, TFTs having a semiconductor layer to which scanning signals are supplied by the scanning lines, pixel electrodes to which image signals are supplied by the data lines through the TFTs, storage capacitors arranged below the data lines, and an insulating film covering the storage capacitors. The data lines can be formed to avoid stepped portions on the surface of the insulating film caused by the height of the storage capacitors. Thus, it can be possible to improve the light shielding performance of the thin film transistors with respect to the semiconductor layer, to reduce or prevent the generation of light leakage current, and to display high-quality images without flicker.
