Abstract
A drive circuit includes: a level shift circuit configured to convert a plurality of first pulse signals to a plurality of low-level set pulse signals, respectively, and output the set pulse signals sequentially to a first transmission line, and configured to convert a second pulse signal to a low-level reset pulse signal and output the reset pulse signal to a second transmission line; a detection circuit configured to output a first detection signal in response to detecting that a first voltage is at a low level, and output a second detection signal in response to detecting that a second voltage is at a low level; and a restoration circuit configured to set a switching element, which is provided between a power supply line of a high-side power supply potential and the first transmission line, to the on state in response to a first-first detection signal output from the detection circuit.
