Embodiment
Below in conjunction with Figure of description the utility model embodiment is described in further detail.
As shown in Figure 2, be the color membrane structure that the utility model embodiment provides, it specifically comprises:
Last substrate 1, following substrate 2, and common electrode layer 3, black matrix" 4, electrochomeric films 5 and pixel electrode layer 6 between last substrate 1 and following substrate 2;
Wherein, this common electrode layer 3 is attached to last substrate 1 lower surface;
