Abstract
An electrochromic display device including: a first substrate; first electrodes parallely extending on the first substrate; a second substrate opposite to the first substrate; second electrodes parallely extending in a direction orthogonal to the first electrodes on the second substrate; and an electrochromic composition layer between the substrates, wherein the device is passive-matrix driven to perform a display by energization between the electrodes, and to perform erasing of the display by energization in a reverse direction, a pixel is formed in a portion where the first electrodes sterically intersect with the second electrodes, and metal electrical wires extending over the regions between the second electrodes and the second substrate along the second electrodes, each of metal electrical wires being conductively connected to each of the second electrodes corresponding to any one of the regions, and insulated from each of the second electrodes corresponding to the other regions.
