Abstract:
1. An electro-optical device, comprising: a thin-film transistor having a channel area that extends in a direction and that intersects a predetermined direction that intersects the direction; a pixel electrode formed correspondingly to the thin-film transistor; a data line extending in the direction in which the channel area extends, the data line having a broad-width portion that overlaps the channel area in plan view; a scanning line extending in the predetermined direction and intersecting the data line and the channel area of the thin-film transistor, the scanning line having a broad-width portion in a portion overlapping the channel area of the thin-film transistor in plan view and a narrow width portion in another portion; a storage capacitor including a pixel-potential capacitor electrode, a fixed-potential capacitor electrode, and a dielectric film interposed between the pixel-potential capacitor electrode and the fixed-potential capacitor electrode; a capacitive line having a portion that serves as the fixed-potential capacitor electrode of the storage capacitor, the capacitive line having a portion extending along the scanning line and a portion extending along the data line, the portion extending along the data line having a width that is equal to or broader than a width of 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 that extends beyond the channel area in a direction extending from the channel area toward the contact hole.
