Abstract
An electrochromic display cell comprises a frame interposed between an ionic conductor and an annular soldered zone sealing a cover of the cell to a substrate of the cell. The frame is squeezed between the cover and the substrate to tightly separate the ionic conductor and the solder, preventing any reaction therebetween. In a preferred embodiment, the frame is made of a thermofusible material. It partially melts during the sealing of the cell, adhering thus very tightly to the cover and to the substrate.
