Abstract

Provided are a drive circuit and a display apparatus capable of making the waveforms of driving signals uniform. The drive circuit comprises a plurality of shift registers each comprising an input end, an output end, and a switching element connected between the input end and the output end. The input ends are respectively connected to a plurality of branch points on an input-signal line arranged on a display panel. The output ends are respectively connected to a plurality of output-signal lines. The drive circuit outputs a driving signal from the output end, on the basis of a signal input through the input end. All or some of the shift registers differ, according to a position of the branch point to which the input end is connected, in resistance value between the input end and the output end while the switching element is ON.
