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.

Abstract
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 selecting 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. The signal driver circuit generates the apply voltages based on the level-shifted display data.
