An electro-optic display cell comprises a solution and an array of display electrodes formed on a semiconductor chip containing integrated circuitry for operating the electrodes to display an image. The cell further comprises arigid support body for the semiconductor chip, a cover plate comprising a transparent window and a metal frame structure for framing the display electrode. The metal frame structure has an inert elastomeric coating on at least the inner sides and top and bottom faces of the frame. A clamping means clamps the frame, cover plate and support body together to form an enclosure for the solution so that the coating on the bottom face of the frame seals against the semiconductor chip to confine the solution to the top surface thereof.
