Abstract: A cholesteric liquid crystal display device (24) has a protective sheet (40) or a stack of protective sheets adhered to the substrate (11) at the front of a stack of cells (10B, 10G, 10R) containing cholesteric liquid crystal material (19). The protective sheet is adhered by a layer of adhesive (40) which is either an adhesive curable by heat or an adhesive curable by light. The adhesive contains a UV blocking agent, for example, a compound based on benzophenone, having a property of reducing the transmission of ultra-violet light through the adhesive. The protective sheet (s) provides protection to the display device and may be made of glass or plastic. Adhering the protective sheet (s) with an adhesive provides the advantages of being much cheaper to implement than laminated glass and of allowing the adhesive to contain the UV blocking agent for UV protection of the cholesteric liquid crystal material.
