Electro-optical device and electronic apparatus
An electro-optical device of the present invention includes pixel electrodes, TFTs electrically connected to the pixel electrodes, and scanning lines and data lines connected to the TFTs on a TFT array substrate. Each scanning line has a broad width portion as a gate electrode in a portion facing a channel area of the TFT and the narrow width portion. As a result, an electro-optical device capable of easily adjusting an arrangement of the gate electrodes and the scanning lines and at the same time precisely driving the TFTs is provided.
1. An electro-optical device, comprising:
a thin-film transistor having a semiconductor layer;
a data line extending in a first direction and overlapping the semiconductor layer, the data line having a narrow-width portion and a broad-width portion that is wider than the narrow-width portion, the broad-width portion overlapping a channel area of the semiconductor layer; and
a capacitive line extending in the first direction and overlapping the data line,
wherein in the first direction, the capacitive line overlaps the broad-width portion of the data line, and the semiconductor layer, and
the capacitive line is wider than the narrow-width portion of the data line in which the semiconductor layer is not provided.
2. The electro-optical device according to claim 1 , further comprising a contact hole electrically connecting the data line and the thin-film transistor, the contact hole being positioned in a portion of the broad-width portion of the data line.
3. The electro-optical device according to claim 1 , further comprising a scanning line extending in a second direction that intersects the first direction, the capacitive line extending in the second direction and overlapping the scanning line.
4. The electro-optical device according to claim 3 , wherein the scanning line includes a broad-width portion in a portion of the scanning line that overlaps the channel area and a narrow-width portion in another portion of the scanning line, the broad-width portion of the scanning line extending in the first direction and overlapping the broad-width portion of the data line.
