ABSTRACT:
An electric cell comprises first and second parallel flexible substrates, set apart from each other at a determined spacing, carrying electrodes on their opposing faces, the substrates enclosing between them a layer of sensitive material which can change its physical properties, in particular its optical properties, as a result of a voltage applied to the electrodes, or change its electrical properties as a result of stress or radiation passing through one of the substrates, the sensitive material being protected from contact with the atmosphere by a sealing frame which connects, in a sealed manner, peripheral parts of the substrates, said frame having a width parallel to the substrates. The electric cell is characterised in that at least the first substrate comprises on its face opposing the second substrate at least a first continuous peripheral groove into which at least a part of the sealing frame extends, the cross-section of the sealing frame being a multiple of an area equal to the product of the width multiplied by the spacing, the thickness of the sealing frame at any point being greater than or equal to the spacing.
