Abstract

A multi-layer film (300), useful as a barrier film in electro-optic displays, comprises a light-transmissive adhesive layer (316), a light-transmissive first protective layer (312), a light-transmissive first moisture barrier layer (308B), an intermediate layer (typically an adhesive layer) (310), a light-transmissive second moisture barrier layer (308A) and a light-transmissive second protective layer (306). The second protective layer may be covered by a hard coat (304) and/or a masking film (302).
