The present invention provides a reflective flexible liquid crystal display, which includes: an upper flexible substrate (1), a lower flexible substrate (3) arranged opposite to the upper flexible substrate (1), a layer of liquid crystal (5) filled between the upper flexible substrate (1) and the lower flexible substrate (3), a circular polarization sheet (7) arranged on an upper surface of the upper flexible substrate (1), and a flexible light guide plate (9) arranged on an upper surface of the circular polarization sheet (7). The upper flexible substrate (1) and the flexible light guide plate (9) are both transparent and the lower flexible substrate (3) includes a reflector layer (37) formed thereon. The reflective flexible liquid crystal display has a simple structure, allowing the liquid crystal display to be applied to flexible displaying.
