摘要: A driver circuit of a display device, which includes TFTs of a single conductivity type and outputs an output signal with normal amplitude. A pulse is inputted to TFTs 101 and 104 to turn ON the TFTs and a potential of a node &agr; is raised. When the potential of the node &agr; reaches (VDD−VthN), the node &agr; becomes in a floating state. Accordingly, a TFT 105 is turned ON and a potential of an output node is raised as a clock signal becomes High level. On the other hand, a potential of a gate electrode of the TFT 105 is further raised due to an operation of a capacitance means 107 as the potential of the output node is raised, so that the potential of the gate electrode of the TFT 105 becomes higher than (VDD+VthN). Thus, the potential of the output node is raised to VDD without causing a voltage drop due to a threshold voltage of the TFT 105. An output at the subsequent stage is then inputted to a TFT 103 to turn the TFT 103 On, while the potential of the node &agr; of TFTs 102 and 106 is dropped to turn the TFT 105 OFF. As a result, the potential of the output node becomes Low level.

摘要: The present invention provides a semiconductor device in which a power line is not affected by noise due to a voltage drop caused by instantaneous high-current consumption in the buffer portion and that has no possibility that a logic portion malfunctions. In a case where the same potential is supplied to a logic portion and a buffer portion, by a method in which separate FPC terminals are used for the logic portion and the buffer portion, or by a method in which the FPC terminal is shared but a power line is branched for the logic portion and the buffer portion at a point close to the FPC terminal, a problem that the logic portion is affected by noise generated by a voltage drop of the power line due to instantaneous high-current consumption in the buffer portion can be prevented.

摘要: To provide a display device with little signal delay and a display device that can operate with low power consumption, parasitic capacitance between a common wiring that applies a common potential to a plurality of pixels and signal lines that input signals for driving the pixels is avoided. Specifically, the common wiring is routed outwardly with respect to an external input terminal to which a signal is input from the, outside, to avoid intersections of the signal lines and the common wiring. Thus, parasitic capacitance between the common wiring and the signal lines is avoided, so that the display device can operate at high speed with low power consumption.
