An optically switchable transparent liquid crystal display consists of a polymer network liquid crystal (PNLC) containing azobenzene and a light source. The PNLC switches between transparent and screen states through photoisomerization of azobenzene. The flexibility and transparency of the PNLC were achieved by combining monomers of monofunctional reactive mesogens and bifunctional methacrylates.
