Abstract
A display apparatus is provided which is capable of improving display quality by expanding the light-emission area of pixels by improving the layout of pixels and common power-feed lines formed on a substrate. Pixels including a light-emission element, such as an electroluminescence element or an LED element, are arranged on both sides of common power-feed lines so that the number of common power-feed lines is reduced. Further, the polarity of a driving current flowing between the pixels and the light-emission element is inverted so that the amount of current flowing through the common power-supply lines is reduced.
