Abstract
A driver IC includes an abnormality detection part for detecting at least one of abnormality of an OE signal, abnormality of a VGH being a signal indicating a High-level voltage, and abnormality of a VGL being a signal indicating a Low-level voltage, a waveform-changing part for changing a waveform of an STV signal being a start signal for generating a gate pulse based on a signal output from the abnormality detection part, and an output part for outputting the STV signal.
