摘要:
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 (7A, 7B) including a light-emission element (40), 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 (7A, 7B) and the light-emission element (40) is inverted so that the amount of current flowing through the common power-supply lines “com” is reduced.
