Abstract

In a passive type EL display apparatus having a matrix structure, column electrodes include first column electrodes (211) corresponding to pixels at odd rows and second column electrodes (212) corresponding to pixels at even rows. The first and second column electrodes are individually driven by respective first and second column drivers (22, 23), while a row driver (21) drives pixels located at odd and even rows adjoining in the column direction, namely row electrodes corresponding to these pixels simultaneously, to thereby execute simultaneous display for one set of odd and even rows. An resulting EL display apparatus can provide reliable display with a small scale circuit without using frame buffers for temporarily storing data to be displayed.
