    • An electrochemical display apparatus in which simple matrix driving is realized, whereby apparatus constitution can be simplified, and the price of the apparatus can be lowered. The electrochemical display apparatus performs display by use of electrochemical deposition/dissolution of a metal. The display apparatus is driven by a simple matrix driving system, in which a deposition overvoltage at the time of deposition of metallic ions as the metal is used as a threshold in the simple matrix driving. A driving voltage is set to be not more than two times the deposition overvoltage. The electrochemical display apparatus includes transparent electrodes and counter electrodes, the display is performed by utilizing deposition/dissolution of the metal on the transparent electrodes, and the potential difference between the metal to be deposited on the transparent electrodes and the counter electrodes is set to be less than the deposition overvoltage. Ideally, the same metal as the metal which is deposited is used for constituting the counter electrodes.
    • 实现简单矩阵驱动的电化学显示装置,由此能够简化装置结构,并且能够降低装置的价格。 电化学显示装置通过使用金属的电化学沉积/溶解来进行显示。 显示装置由简单矩阵驱动系统驱动,其中在简单矩阵驱动中使用作为金属沉积金属离子时的沉积过电压作为阈值。 驱动电压设定为不超过沉积过电压的两倍。 电化学显示装置包括透明电极和对电极,通过利用金属在透明电极上的沉积/溶解进行显示,并且将要沉积在透明电极和对置电极上的金属之间的电位差设定为 小于沉积过电压。 理想地,与沉积的金属相同的金属用于构成对电极。
