A multidirectional asymmetrical microlens array light control film (MAMA-LCF) which can direct light incident from multiple directions collectively for viewing was studied. The MAMA-LCF which was constructed with an asymmetrical microlens array and laminated onto the front surface of reflective color super twisted-nematic liquid crystal display (STN-LCD), yielded a maximum gain of about 5 × the MgO standard white in a typical viewing region without visible dispersion. It was shown that the use of MAMA-LCF can effectively enhance the brightness and image quality of reflective color STN in an ambient environment.
