Abstract
An electro-optic display containing a two-phase, light-transmissive electrically-conductive layer comprising a first phase made of a highly electronically-conductive matrix and a second phase made of a polymeric material composition having a controlled volume resistivity. The matrix of the first phase may be formed from carbon nanotubes, silver nanowires, a metal coated open foam structure, or a printed mesh of wires. The polymeric material composition of the second phase may be a conductive polymer, or a polymer and an additive such as a salt, a polyelectrolyte, a polymer electrolyte, or a solid electrolyte, or combinations thereof.
