Abstract
An electro-optical device includes: a wiring substrate connected to an electro-optical panel; and a driving IC mounted on the wiring substrate. The driving IC includes a first wiring line extending in one direction, and the wiring substrate includes a first reinforcing line connected to both ends of the first wiring line at a position overlapping the driving IC and electrically connected in parallel with the first wiring line. For example, the first wiring line extends from an input terminal to other terminals, and the wiring substrate includes a wiring line that supplies power to the input terminal via an electrode to which the input terminal is connected and a first reinforcing line connected to the electrodes to which the other respective terminals are connected.
