A color display apparatus includes a display unit having electro-optical elements arranged in a row direction and a column direction, scanning lines provided in respective rows of the electro-optical elements to select respective rows, and data lines provided in respective columns and supplying data signals to electro-optical elements in the row which the scanning lines select, and conversion circuits each of which receives a digital video signal and converts the digital video signal to an analog video signal. In addition, a first dispersion circuit receives the analog video signals outputted from the conversion circuits and exchanges an arrangement of the analog video signals to output to bus lines, column drive circuits sample the analog video signals in the bus lines in a time sharing manner and generate and output the data signals, and a second dispersion circuit receives the data signals outputted from the column drive circuits and rearranges the data signals to output to the data lines. The rearranging of the data signals by the second dispersion circuit restores the exchanging of the arrangement by the first dispersion circuit.
