Electro-optical apparatus, matrix substrate, and electronic unit

摘要

The invention provides an electro-optical apparatus having a power-supply wiring structure that is capable of supplying a sufficient electrical power to a common electrode of electro-optical devices. An electro-optical apparatus according to the present invention includes electro-optical devices having a laminated structure including first electrode layers formed on or above a viewing area of a substrate and a second electrode layer formed on or above the first electrode layers. The laminated structure further includes first power lines to supply a voltage to the first electrode layers and second power wiring electrically connected to the second electrode layer. The first power lines and the second power lines are arranged on or above the viewing area and are arranged in the same layer as the first electrode layers or below the first electrode layers.
