The invention concerns a process for the production of LCDs (liquid crystal display). Those LCDs can be in particular PDLCDs (polymer dispersed LCDs) which are to be produced for example in a roll-to-roll process.
The production of PDLCDs in a roll-to-roll process has hitherto been obstructed by virtue of the fact that the functional layer of the respective PDLCD which comprises a porous polymer, that is to say support, matrix filled with LC material, is not closed at the surface. After hardening of the matrix the LCs are present in a non-crosslinked, fluid state. By virtue of the fluid LCs at the surface of the matrix, it has hitherto not been possible to carry out a usually multi-stage roll-to-roll process because the functional layer would stick to other surfaces which are brought into contact therewith. That would result in damage to the functional layer.
