<P>PROBLEM TO BE SOLVED: To provide an image display device capable of achieving multi-gradation expression including neutral color while suppressing undesirable "flicker" during renewing screen with a simple configuration. <P>SOLUTION: Electrophoretic particles includes n-kinds of charged particles C1, ... Ck, ..., Cn each has a different threshold voltage at which each charged particle starts color forming and electrophoresis. Each charged particle C1, ..., Ck, ..., Cn satisfies a relation characteristics of threshold voltage of charged particle C1>...>threshold voltage of charged particle Ck>...>threshold voltage of charged particle Cn. Voltage applying means transits the relative color density of each charged particle to a relative color density corresponding intermediate transition state in an order of charged particle C1→, ..., →Ck→, ..., →Cn on each applied voltage drive waveform during renewing a screen to thereby finally renew the screen to a new screen having a desired density. <P>COPYRIGHT: (C)2013,JPO&INPIT |
