Abstract
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.
Claims1
An electro-optical device, comprising:
- a thin-film transistor having a channel area;
- a pixel electrode electrically connected to the thin-film transistor;
- a data line extending in a direction, the data line having a narrow-width portion and a broad-width portion that is wider than the narrow-width portion, a portion of the broad-width portion overlapping the channel area in plan view;
- a scanning line intersecting the data line;
- a capacitive line having a portion extending along the data line that is at least as wide as the data line;
- and
- a contact hole electrically connecting the data line and the thin-film transistor, the contact hole being positioned at a portion of the broad-width portion of the data line.
