1. An electric cell of the type comprising a first and a second parallel flexible substrates, set apart from each other at a determined distance, carrying electrodes on their opposing faces, these substrates enclosing between them a layer of sensitive material which can change its physical properties as a result of a voltage applied to the electrodes, said sensitive material being protected from contact with the atmosphere by a sealing frame which connects, in a sealed manner, peripheral parts of said substrates, said frame having a width parallel to the substrates, wherein 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 said sealing frame extends, the cross-section of the sealing frame being a multiple of an area equal to the product of said width multiplied by said spacing, the thickness of the sealing frame at any point being greater than or equal to said spacing and said multiple being equal to or greater than 2.
