Abstract
For the purpose of providing a display apparatus 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 (A,B) including a light-emission element (), such as an electroluminescence element or an LED element, are arranged on both sides of common power-feed lines (com) so that the number of common power-feed lines (com) is reduced. Further, the polarity of a driving current flowing between the pixels (A,B) and the light-emission element () is inverted so that the amount of current flowing through the common power-supply lines 'com' is reduced.
