Abstract: A bootstrap circuit comprises: a first transistor connecting a first power supply with an output node; and a second transistor applying a first input signal to a gate node of the first transistor and having a conductivity type identical to that of the first transistor. A second input signal obtained by inverting a level of the first input signal, delaying the inverted signal, and adding a direct current bias to the delayed signal is inputted to a gate node of the second transistor.

Abstract: Disclosed is a display apparatus comprising an active matrix display section including a plurality of signal lines and scan lines, arranged in a matrix on a substrate, and a plurality of pixels and active elements arranged at intersections of the signal and scan lines, a scan line driving circuit for driving the scan lines and a signal line driving circuit for driving the signal lines. The display section has a non-rectangular shape. The active elements that make up the scan line driving circuit and/or the signal line driving circuit are formed by the same manufacturing process as that for forming the active elements in the active matrix display section. The scan line driving circuit and/or the signal line driving circuit are each a set of circuit units having the same function. These circuit units are arranged to conform to and extend around the outer circumference of the non-rectangular display section.

Abstract: A power supply circuit is provided which is capable of preventing a drop in an output voltage of the power supply circuit used as a DC/DC converter made up of single and conductive type (n-type or p-type) MOS transistors and of improving efficiency. Since a control voltage having an amplitude [2×VDD] is applied from a level shift circuit to a charge-pump circuit, even when potentials at nodes becomes a level [2×VDD], pMOS transistors are kept in an OFF state, thereby preventing leakage of currents from pMOS transistors. This avoids a drop in an DC output voltage. As inputs to the level shift circuits, potentials at nodes of the charge-pump circuit are used and, therefore, even if potentials at nodes of the level shift circuits are high, pMOS transistors are kept in an OFF state.
