Abstract

An electrochromic display device (100,101) including: a first substrate (10); first electrodes (20) parallely extending on the first substrate (10); a second substrate (30) opposite to the first substrate (10); second electrodes (40) parallely extending in a direction orthogonal to the first electrodes (20) on the second substrate (30); and an electrochromic composition layer (50) between the substrates (10,30), wherein the device (100,101) is passive-matrix driven to perform a display by energization between the electrodes (20,40), and to perform erasing of the display by energization in a reverse direction, a pixel (60) is formed in each portion where the first electrodes (20) sterically intersect with the second electrodes (40), and metal electrical wires (41,42,43,44) extending over separate regions (R1,R2,R3,R4) of the second electrodes (40) and in a direction along the second electrodes (40), each of the metal electrical wires (41,42,43,44) being conductively connected to a respective one of the regions (R1,R2,R3,R4), and insulated from the other regions of a respective second electrode.
