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.
