Abstract
A signal line drive circuit and a scanning line drive circuit are capable of being driven bidirectionally. A display apparatus includes a plurality of signal paths each of which transmit a signal outputted from a final-stage circuit thereof when the signal line circuit and/or the scanning line circuit is driven in a forward or reverse direction, and output paths formed by connecting the plurality of signal paths. There are provided a buffer unit and a switching element in each of the plurality of signal paths, and there is provided a buffer unit in each output path. Each of the switching elements in the plurality of signal paths is turned on according to a drive direction in the signal line drive circuit and/or the scanning line drive circuit, and then a target signal is selected and outputted to the output paths.
