摘要： In a driver circuit of a display device handling a digital image signal, there is provided a driver circuit with a structure in which the timing of holding the image signal in a latch circuit is not influenced by a delay of a sampling pulse. A pre-charge TFT (102) is turned ON in a return line period and an input terminal of a holding portion (101) is set as Hi (VDD). When there is input to all the three signals, the sampling pulse, and a multiplex signal and the digital image signal which are input from the outside, TFTs (104 to 106) all turn ON, and the potential of the input terminal of the holding portion (101) becomes a Lo potential. Thus, holding of the digital image signal is performed. A sampling pulse width is wider than a pulse width of the two signals input from the outside, and the output periods of the two signals input from the outside are completely included in an output period of the sampling pulse. Thus, even if a slight delay is generated, there is no influence on the holding timing, and the holding timing may be easily determined.

摘要： Semiconductor elements deteriorate or are destroyed due to electrostatic discharge damage. The present invention provides a semiconductor device in which a protecting means is formed in each pixel. The protecting means is provided with one or a plurality of elements selected from the group consisting of resistor elements, capacitor elements, and rectifying elements. Sudden changes in the electric potential of a source electrode or a drain electrode of a transistor due to electric charge that builds up in a pixel electrode is relieved by disposing the protecting means between the pixel electrode of the light-emitting element and the source electrode or the drain electrode of the transistor. Deterioration or destruction of the semiconductor element due to electrostatic discharge damage is thus prevented.

摘要： A light emitting device that achieves long life, and which is capable of performing high duty drive, by suppressing initial light emitting element deterioration is provided. Reverse bias application to an EL element (109) is performed one row at a time by forming a reverse bias electric power source line (112) and a reverse bias TFT (108). Reverse bias application can therefore be performed in synchronous with operations for write-in of an image signal, light emission, erasure, and the like. Reverse bias application therefore becomes possible while maintaining a duty equivalent to that of a conventional driving method.

摘要： Brightness irregularities that develop in a light emitting device due to is persion among pixels in the threshold values of TFTs used for supplying electric current to light emitting devices become obstacles to improved image quality of the light emitting device. As an image signal input to a pixel from a source signal line, a desired electric potential is applied to a gate electrode of a TFT for supplying electric current to an EL device, through a TFT having its gate and drain connected to each other. A voltage equal to the TFT threshold value is produced between the source and the drain of the TFT 105. An electric potential in which the image signal is offset by the amount of the threshold value is therefore applied to the gate electrode of the TFT. Further, TFTs are disposed in close proximity to each other within the pixel, so that dispersions in the TFT characteristics do not easily develop. A desired drain current can thus be supplied to the EL device even if there is dispersion in the threshold values of the TFTs among pixels, because this is offset by the threshold value of the TFT.
