Liquid crystal display devices

A display device comprising:

• a liquid crystal cell comprising liquid crystal material contained between a control component comprising at least an organic semiconductor layer supported on a first support film, and a counter component comprising a second support film;
• a first polarising filter component on the opposite side of the control component to the liquid crystal material;
• a second polarising filter component on the opposite side of the counter component to the liquid crystal material;
• and
• one or more oxygen-permeable, self-supportable films having a total thickness of at least 185 microns between the first polarising filter component and the control component and/or between the second polarising filter component and the counter component, wherein the one or more oxygen-permeable self-supportable films comprise one or more self-supportable adhesive films, wherein all of the liquid crystal cell, the first and second polarising filter components and the one or more oxygen-permeable self-supportable films are wholly encapsulated by one or more moisture barrier films and/or layers.
