Abstract
The invention provides power-supply wiring preferable for large displays. An electro-optical device according to the present invention includes a pixel area including electro-optical elements driven by power supplied from power-supply circuits. The electro-optical device includes basic power-supply lines, which receive a power-supply voltage output from the power-supply circuits and which are formed on the upper portion of a substrate, and includes main power-supply lines which intersect the basic power-supply lines and which are formed on the upper portion of the substrate. The power-supply voltage is supplied to the electro-optical elements via the main power-supply lines.
Claims7
An electro-optical device, comprising:
- a first substrate provided with a rectangular pixel area including electro-optical elements,
- a plurality of second substrates, which are different from the first substrate and which are provided with a power source line that supplies a power source voltage to drive the electro-optical elements, and
- the second substrates being arranged on at least a side of a pair of opposite sides of the pixel area.
