<p>The invention provides an active matrix EL display device which can perform a clear multi-gray scale color display. In particular, the invention provides a large active matrix EL display device at low cost by a manufacturing method which can selectively form a pattern. Power supply lines in a pixel portion are arranged in matrix by the manufacturing method which can selectively form a pattern. Further, capacitance between wirings is reduced by providing a longer distance between adjacent wirings by the manufacturing method which can selectively form a pattern.</p>
