Patent ID: 7136117

Claim:
An electro-optical device, comprising: a substrate; scanning lines above the substrate and extending in a predetermined direction; data lines above the substrate and extending in a direction intersecting the scanning lines; thin-film transistors formed correspondingly to intersecting areas of the scanning lines and the data lines; pixel electrodes formed correspondingly to the thin-film transistors; and a respective scanning line having a broad width portion as a gate electrode in a portion facing a channel area of a respective thin-film transistor and a narrow width portion in another portion, the channel area extending in a direction in which the data lines extend, the respective scanning line extending in a direction intersecting a direction in which the channel area extends, and the broad width portion extending in a direction intersecting a direction in which the scanning line extends and extending in a single direction or bi-direction in which the channel area extends, the broad width portion and the channel area extending in a direction extending from the channel area to a contact hole, the contact hole electrically connecting the channel area and the data line, the pixel electrodes being arranged in a matrix shape, the respective channel area being formed in an intersecting area in which a first long gap extending through a space between the pixel electrodes sandwiching the scanning line and being adjacent to each other and a second long gap extending through a space between the pixel electrodes sandwiching the data line and being adjacent to each other, are intersected, the narrow width portion being formed at a position deviated from a center of the first gap, and the broad width portion being formed at the center of the first gap in the intersecting area.
