摘要： The reliability of an EL element is enhanced while the increase of the electric power consumption is suppressed. It becomes possible that in a SES drive, the reverse bias is applied to the EL element driven at a constant electric current. Moreover, the application of the reverse bias is performed by varying only the counter electrode, and thus withstand voltage of TFT and the increase of the electric power consumption due to the increase of voltage of the gate signal line drive circuit, which becomes a problem when changing greatly the electric current supplying line, can be suppressed. Furthermore, the reduction of the electric power consumption can also be achieved while the enhancement of the reliability is secured by making the reverse bias smaller than the forward bias. Moreover, the increase of the number of electric sources can be also suppressed by making the potential be in common with the potential of the electric source of the source signal line drive circuit or the gate signal line drive circuit, at the time when the reverse bias is applied.

摘要： A method of efficiently forming a circuit using a thin film transistor with a semiconductor layer in which preferable crystallinity is obtained is provided. A location on which stress concentrates according to crystallization of a semiconductor layer formed on a substrate having unevenness corresponds to the edges and their vicinities of the unevenness provided on the substrate, that is, the boundary between a concave portion and a convex portion and its vicinities. Thus, the location in which stress concentration is caused can be specified and controlled according to the shape of a slit-shaped base layer. In addition, an island-like semiconductor layer (1305) which becomes the active layer of a TFT is formed on the concave portion or the convex portion of the substrate having the unevenness. At this time, at least a portion which becomes the channel formation region of the TFT is formed without crossing the boundary between the concave portion and the convex portion. Such TFTs are used in parallel to construct a TFT having a large channel width so that fluctuation in electrical characteristics is averaged.

摘要： In order to increase the continuous operating time of a display device driven by a battery or the like, and a portable information terminal using the same, the volume and weight of the battery are increased. Thus, there arises a trade-off between the increased capacity of the battery and the portability of the device/terminal. Therefore, the invention provides a display device with portability ensured, which is capable of operating continuously for long periods and a portable information terminal using the same. In the display device, TFTs and an RFID tag are formed over the same insulating substrate. The RFID tag detects signals from a reader/writer, and generates DC power based on the signals. While the RFID tag is detecting signals, the display device is driven by the DC power generated in the RFID tag.

摘要： The invention provides a display device and an electronic apparatus which can reduce power consumption in the case of being driven by using a digital time grayscale method. According to the invention, a row in which all the pixels display black is focused on in a plurality of pixels arranged in matrix, and sampling of data which is to be inputted to the pixels arranged in the row is not performed. Then, in a period during which the data sampling is not performed, the operation of a shift register in a source driver and sampling operation of a video signal in a first latch circuit are stopped. The invention which has the aforementioned characteristics can temporally stop operation of the source driver to reduce power consumption. In particular, the invention can stop operation of the source driver which consumes much power in the display device, leading to dramatic reduction in power consumption.
