摘要： In one embodiment of the present invention, a unit circuit of a shift register includes a bootstrap circuit configured with a transistor T1, a transistor T2 and a capacitor, a transistor T3, a transistor T4, and a reset signal generation circuit. By use of two-phase clock signals and whose high level periods do not overlap with each other, the reset signal generation circuit generates a reset signal which is at a high level in a normal state and changes to a low level when an input signal turns into the high level. During a period that the reset signal is at the high level, transistors T3 and T4 perform discharge of a node and pull-down of an output signal. Thus, it is possible to obtain a power-saving shift register that fixes an output signal at a low level in a normal state without allowing a through current to flow therein.

摘要： A stage of the shift register has (i) a set-reset type flip-flop which receives an initialization signal and (ii) a signal generating circuit which receives a simultaneous selection signal and which generates an output signal by use of an output of the flip-flop. In at least one example embodiment, the output of the flip-flop becomes inactive regardless of whether a setting signal and a resetting signal are active or inactive, as long as the initialization signal is active. The initialization signal becomes active before the end of the simultaneous selection, and then becomes inactive after the end of the simultaneous selection. This makes it possible to stabilize operation of the shift register after the end of simultaneous selection of a plurality of signal lines carried out by the display driving circuit at a predetermined timing.

摘要： In a storage capacitor line drive circuit driving a storage capacitor line of an active-matrix display device and driven by outputs of a scanning signal line drive circuit, at least one (VSS) of a high-potential supply voltage (VDD) and a low-potential supply voltage (VSS) differs from a supply voltage (GVSS) of a corresponding logical level of the scanning signal line drive circuit, the high-potential supply voltage and the low-potential supply voltage being used for generating a signal voltage of a preceding stage to an output stage. This makes it possible to achieve a storage capacitor line drive circuit capable of avoiding malfunctioning even in a case where the storage capacitor line drive circuit receives noise from a scanning signal line, and a display device including the storage capacitor line drive circuit.
