ABSTRACT:
There is disclosed a salt of a polymer having charged anionic functionalities used as a dispersant in a dispersion solution containing a pigment and used for forming a first pigment layer. A substance which forms a salt with a polymer having charged anionic functionalities is mixed into a solution applied on the pigment layer, and/or mixed into a developing solution. The formed layers are patterned and thus a display screen is obtained.
