Abstract

A first electro-optic display comprises first and second substrates, and an adhesive layer and a layer of electro-optic material disposed between the first and second substrates, the adhesive layer comprising a mixture of a polymeric adhesive material and a hydroxyl containing polymer having a number average molecular weight not greater than about 5000. A second electro-optic display is similar to the first but has an adhesive layer comprising a thermally-activated cross-linking agent to reduce void growth when the display is subjected to temperature changes. A third electro-optic display, intended for writing with a stylus or similar instrument, is produced by forming a layer of an electro-optic material on an electrode; depositing a substantially solvent-free polymerizable liquid material over the electro-optic material; and polymerizing the polymerizable liquid material.
