Signal processing circuit, inverter circuit, buffer circuit, driver circuit, level shifter, and display device

摘要

A signal processing circuit of the present invention includes: first and second input terminals; an output terminal; a bootstrap capacitor; a first output section connected to the second input terminal and the output terminal; a second output section connected to the first input terminal, a first power source, and the output terminal; an electric charge control section for controlling the electric charge of the bootstrap capacitor, the electric charge control section being connected to the first input terminal; and a resistor having (i) a first end connected to the output terminal and (ii) a second end connected to a second power source. This arrangement allows the signal processing circuit to maintain an output potential even after a bootstrap effect has worn off.
