Method for producing a flexible electro-optic cell

A method of producing a flexible cell unit enclosed by a border seal and filled with an electro-optic material, the flexible cell unit having a first substrate and a second substrate separated by a controlled distance maintained by a plurality of unpatterned spacers within the flexible cell unit, the method comprising:

• providing two sheets of flexible material as the first and second substrates,
• depositing an electro-optic material on at least one substrate, wherein the electro-optic material is non-discrete non-encapsulated, non-polymeric, and contains less than 1% polymerizable material;
• and
• pairing the first and second substrates while roll-filling the flexible cell unit with the electro-optic material using one or more lamination rollers so that the electro-optic material completely fills the controlled distance between the first and second substrates, wherein the controlled distance is maintained by the unpatterned spacers.
