摘要： An object of an embodiment of the present invention is to manufacture a semiconductor device with high display quality and high reliability, which includes a pixel portion and a driver circuit portion capable of high-speed operation over one substrate, using transistors having favorable electric characteristics and high reliability as switching elements. Two kinds of transistors, in each of which an oxide semiconductor layer including a crystalline region on one surface side is used as an active layer, are formed in a driver circuit portion and a pixel portion. Electric characteristics of the transistors can be selected by choosing the position of the gate electrode layer which determines the position of the channel. Thus, a semiconductor device including a driver circuit portion capable of high-speed operation and a pixel portion over one substrate can be manufactured.

摘要： Objects are to provide a display device the power consumption of which is reduced, to provide a self-luminous display device the power consumption of which is reduced and which is capable of long-term use in a dark place. A circuit is formed using a thin film transistor in which a highly-purified oxide semiconductor is used and a pixel can keep a certain state (a state in which a video signal has been written). As a result, even in the case of displaying a still image, stable operation is easily performed. In addition, an operation interval of a driver circuit can be extended, which results in a reduction in power consumption of a display device. Moreover, a light-storing material is used in a pixel portion of a self-luminous display device to store light, whereby the display device can be used in a dark place for a long time.

摘要： Etching of a semiconductor layer including a part over a gate wiring and formation of a contact hole for connection between a pixel electrode and a drain electrode are performed by one-time photolithography step and one-time etching step; thus, the number of photolithography steps is reduced. The exposed part of the gate wiring is covered by an insulating layer, and this insulating layer also functions as a spacer for maintaining a space for a liquid crystal layer. By the reduction in the number of photolithography steps, a liquid crystal display device can be provided at lower cost and higher productivity. Using an oxide semiconductor for the semiconductor layer can realize a liquid crystal display device with low power consumption and high reliability.

摘要： In a display device using a delta arrangement, in a case where a circuit of a large number of elements such as a static memory is arranged every pixel, a wire becomes complicated to cause wiring delay. A shape of a pixel electrode is formed polygonally to arrange in a case where the number of elements such as a static memory is large or in a case where an area of an element required to be included in a pixel is large in a delta arrangement. The shape of the pixel electrode is arranged in a polygon so that a wire along a pixel shape can be used. Even in a case of a pixel with a large number of elements, parasitic resistance of a wire and parasitic capacitance of a wire can be reduced so that wiring delay can be solved.
