Electro-optic displays, and materials and methods for production thereof

A process for forming a flexible electro-optic display, the process comprising:

• providing a flexible backplane comprising at least one electrode;
• providing a flexible front plane laminate comprising a flexible light-transmissive electrically-conductive layer;
• a flexible layer of a solid electro-optic medium;
• a flexible adhesive layer and a release sheet;
• removing the release sheet from the front plane laminate;
• and
• laminating the front plane laminate to the backplane to form an electro-optic display,
• wherein a stiffening layer is secured to at least one of the front plane laminate and the backplane prior to the lamination, the stiffening layer serving to increase the stiffness of the front plane laminate and/or backplane.

A front plane laminate comprising, in order, a light-transmissive electrically-conductive layer;

• a layer of an electro-optic medium;
• a layer of cross-linked adhesive;
• a layer of non-cross-linked adhesive;
• and a release sheet.

A double release film comprising:

• a layer of a solid electro-optic medium having first and second surfaces on opposed sides thereof;
• a first adhesive layer on the first surface of the layer of solid electro-optic medium;
• a second adhesive layer on the second surface of the layer of solid electro-optic medium;
• and
• a release sheet disposed on the opposed side of the first adhesive layer from the layer of solid electro-optic medium,
• wherein one of the first and second adhesive layers comprises a first sub-layer of cross-linked adhesive adjacent the surface of the layer of solid electro-optic medium, and a second sub-layer of non-cross-linked adhesive.
