ABSTRACT:
An image display apparatus include a plurality of scan wirings and a plurality of modulation wirings forming a matrix, display elements to be driven in matrix according to a scan signal applied by the scan wirings and a modulation signal applied by the modulation wirings, and a scan circuit for scanning the plurality of scan wirings and applying a scan signal to the selected scan wiring. An output circuit stores an input signal to be inputted in time-series, generates a plurality of outputs consisting of a time-series signal for generating a modulation signal based on the stored result and outputs the plurality of outputs to a plurality of output paths as parallel outputs. In addition, a modulation side drive circuit outputs parallel modulation signals based on the time-series signal for generating a modulation signal. The modulation side drive circuit is provided in a plural form corresponding to each of the plurality of output paths and each of the plurality of modulation side drive circuits supplies the modulation signal to a part of and a plurality of modulation wirings among the plurality of modulation wirings, and the output circuit starts to output at least one of the parallel outputs before storing the input signal for constituting the rearmost end among respective rear ends of the parallel outputs.
