Abstract
A display device including a liquid crystal cell having liquid crystal material contained between a control component having at least an organic semiconductor layer supported on a first support film, and a counter component having a second support film. The device further includes a first polarising filter component on the opposite side of the control component to the liquid crystal material and a second polarising filter component on the opposite side of the counter component to the liquid crystal material. The device also includes 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.
