    Abstract: 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.

    Abstract: To provide a semiconductor device which operates stably with few malfunctions due to noise, with low power consumption, and little variation in characteristics; a display device including the semiconductor device; and an electronic device including the display device. An output terminal is connected to a power supply line, thereby reducing variation in electric potential of the output terminal. In addition, a gate electrode potential which turns ON a transistor is maintained due to the capacitance of the transistor. Further, change in characteristics of the transistor is reduced by a signal line for reverse bias.

    Abstract: To provide an active matrix display device in which power consumption of a signal line driver circuit can be suppressed, so that power consumption of the entire memory can be suppressed. A plurality of memory circuits which can write data of a video signal input to a pixel in one line period and can hold the data are provided in a signal line driver circuit of a display device. Then, the data held in each memory circuit is input to a pixel of a corresponding line as a video signal. By providing two or more memory circuits in a driver circuit, pieces of data of video signals corresponding to two or more line periods can be concurrently held in the memory circuits.
