Abstract
An image display apparatus includes a plurality of display devices, a plurality of scan interconnections and a plurality of modulation interconnections, a scanning circuit for applying a scanning signal to the scan interconnections, and a modulation circuit for applying a modulation signal to the modulation interconnections. The scanning circuit applies the scanning signals to a group of scan interconnections selected from the plurality of scan interconnections in one select period, and applies the scanning signals, in a subsequent select period, to the plurality of scanning interconnections which were shifted with one scan interconnection portion from the group of scanning interconnections to which the scanning signals were applied in a previous select period. The scanning signals which have the same polarity to the modulation signal in successive two select periods are applied to the scanning interconnection to which the scanning signals should be applied repeatedly, and the output from the scanning circuit has a portion in which signal level is controlled to a non-selection electric potential level between the scanning signals which are applied repeatedly to the scanning interconnection. The scanning circuit is configured to apply scanning signals with different selection electric potentials to a plurality of scan interconnections which are selected in one select period.
