1. A display apparatus comprising:

  • a plurality of pixel portions arranged in a matrix;

    a signal driver circuit which generates apply voltages corresponding to display data, and applies the apply voltages to the pixel portions;

    a scan driver circuit which applies a selective voltage to selected ones of the pixel portions; and

    a level shifter circuit which converts a voltage level of the display data into a drive voltage level of the signal driver circuit, thereby producing level-shifted display data;

    wherein the signal driver circuit generates the apply voltages based on the level-shifted display data.
