PURPOSE:To improve the response speed of an ECD having a large number of segments by bringing a conductive material into direct contact with a transparent electrodes of a display electrode substrate through a through-hole, and making conductive connections between the transparent electrode and an electrode on the reverse surface of a counter electrode substrate. CONSTITUTION:Transparent electrode 2 as display electrodes and electrochromic materials 3 are formed successively in desired patterns on the transparent substrate to constitute the display electrode substrate 1. The counter electrode substrate 4 has counter electrodes and also has through-holes 5. A projection 7 is formed at each through-hole 5. The substrates 1 and 4 are put opposite to each other across an electrolyte, and sealed at the peripheral parts and also adhered together with a seal material 14 provided annularly to peak parts of projections 7. A conductive material 15 is charged in through-holes 5 to connect the electrodes 2 to conductors 8 on the reverse surface of the substrate 4. Thus, conductive connections are made reliably with low lead resistance and the response speed of the ECD including a large number of segments is improved.
