Abstract:
An image display device, comprising:(MÃ—N) organic EL (Electro-Luminescent) elements arranged two-dimensionally in M rows and N columns, where M and N are predetermined natural numbers; M rows of data lines to which data voltages, in which the light-emission luminances of said (MÃ—N) organic EL elements are individually set, are applied in order; N columns of scan lines to which a scan voltage is applied in order in synchronization with data voltages that are applied to said M rows of data lines; M rows and N columns of switching elements that are turned on one column at a time by the scan voltage that is applied in order to said N columns of scan lines; M rows and N columns of voltage holding means for individually holding the (MÃ—N) data voltages that are applied from said M rows of data lines in accordance with the ON state of said M rows and N columns of switching elements; a pair of power supply electrodes to which a predetermined drive voltage is constantly applied; M rows and N columns of drive transistors for applying said drive voltage that is constantly applied to said power supply electrodes to said (MÃ—N) organic EL elements in accordance with each of the voltages held by said (MÃ—N) voltage holding means; and conduction control elements for halting the application of the drive voltage to M said organic EL elements of the nth column immediately before a scan voltage is applied to said scan line of the nth column, where 1&lE;n&lE;N.
