Abstract:	A multidirectional asymmetrical microlens array light control film (MAMA-LCF) which can direct light incident from multiple directions collectively for viewing is demonstrated in achieving much enhanced brightness in reflective color super twisted-nematic liquid crystal displays (STN-LCDs). The MAMA-LCF, constructed with an asymmetrical microlens array and laminated onto the front surface of reflective color STN-LCDs, can yield a maximum gain of about 5 x the MgO standard white in a typical viewing region without visible dispersion, moire or parallax effects.
