Abstract
The invention relates to a reflective display () comprising a substrate () and a reflective layer (), e.g. comprising microcapsules () with an electrophoretic suspension arranged to reflect incident light () passing through the substrate (), wherein the substrate () is structured so as to form a plurality of funnel-shaped protrusions () with reflective walls (), the protrusions being oriented with a top end () facing towards the reflective layer and a base end () facing away from the reflective layer. According to this design, light that is reflected at sufficiently large reflection angles will experience one or more reflections by the protrusion walls (). At each reflection the angle of propagation of the light () traveling through the substrate is decreased by twice the angle alpha between the wall () and the normal of the reflective layer ().
