Abstract
An electro-optical device substrate is provided comprising a base, and a plurality of wirings formed on the base. In at least one of the wirings, there is, in a bent portion of the wirings, a portion whose line width W0 gradually increases from a first side of the base to a second side. By preparing a portion having a large line width lowers the wiring resistance of the wirings, thereby preventing crosstalk from being generated in a display region of the electro-optical device.
Claims18
An electro-optical device substrate, comprising:
- a base with a first side and a second side opposite from each other, and
- a plurality of wirings formed on the base,
- wherein at least one of the wirings has a portion whose width gradually increases from the first side of the base to the second side of the base, each of the plurality of wirings having a bent portion with a width that is greater than at a portion other than the bent portion.
An electro-optical device, comprising:
- a substrate having a first edge and a second edge opposite from each other;
- a plurality of wirings formed over the base, each of the wirings having a straight portion and a bent portion continuous with each other, the straight portions extending in a direction following a first edge of the substrate and the bent portions extending in a direction that intersects the first edge, the bent portions having a width that is greater than the straight portion and that increases with increasing proximity to one of the first edge.
