摘要： An object is to provide a semiconductor device having a structure in which parasitic capacitance between wirings can be efficiently reduced. In a bottom gate thin film transistor using an oxide semiconductor layer, an oxide insulating layer used as a channel protection layer is formed above and in contact with part of the oxide semiconductor layer overlapping with a gate electrode layer, and at the same time an oxide insulating layer covering a peripheral portion (including a side surface) of the stacked oxide semiconductor layer is formed. Further, a source electrode layer and a drain electrode layer are formed in a manner such that they do not overlap with the channel protection layer. Thus, a structure in which an insulating layer over the source electrode layer and the drain electrode layer is in contact with the oxide semiconductor layer is provided.

摘要： A method of manufacturing, with high mass productivity, liquid crystal display devices having highly reliable thin film transistors with excellent electric characteristics is provided. In a liquid crystal display device having an inverted staggered thin film transistor, the inverted staggered thin film transistor is formed as follows: a gate insulating film is formed over a gate electrode; a microcrystalline semiconductor film which functions as a channel formation region is formed over the gate insulating film; a buffer layer is formed over the microcrystalline semiconductor film; a pair of source and drain regions are formed over the buffer layer; and a pair of source and drain electrodes are formed in contact with the source and drain regions so as to expose a part of the source and drain regions.

摘要： An object is to provide a semiconductor device having a structure with which parasitic capacitance between wirings can be sufficiently reduced. An oxide insulating layer serving as a channel protective layer is formed over part of an oxide semiconductor layer overlapping with a gate electrode layer. In the same step as formation of the oxide insulating layer, an oxide insulating layer covering a peripheral portion of the oxide semiconductor layer is formed. The oxide insulating layer which covers the peripheral portion of the oxide semiconductor layer is provided to increase the distance between the gate electrode layer and a wiring layer formed above or in the periphery of the gate electrode layer, whereby parasitic capacitance is reduced.

摘要： A power saving system using a plurality of flexible display devices placed on various places is provided. A structure of a bendable portion in a display device is improved. Specifically, a wiring partly including a metal nanoparticle is used. Openings are formed in an insulating layer so that the wiring becomes substantially longer by meandering in cross section. When a plurality of openings are formed and aligned, a portion that is easy to bend is formed along the line where they are aligned. A plurality of display panels are used for one display portion. The flexible display portion can be provided on a surface, specifically, a curved surface of furniture such as a chair or a sofa.

摘要： Provided is a novel display panel that is highly convenient or reliable. The display device has two display modes: a reflective display mode and a light-emitting display mode. In the light-emitting display mode, light display is performed by transmitting light from a light-emitting element overlapping with an opening in a pixel electrode of a reflective display element. A switching element of the reflective display element and a switching element electrically connected to the light-emitting element are formed over one substrate. They are each a transistor whose channel formation region is formed in a silicon-containing film, specifically a polysilicon film.
