ABSTRACT:
A light-emissive device including: a light-emissive region (12); a first electrode (10) located on a viewing side of the light-emissive region for injecting charge carriers of a first type; and a second-electrode (11) located on a non-viewing side of the light-emissive region for injecting charge carriers of a second type; and wherein there is a reflectivity-influencing structure (13) located on the non-viewing side of the light-emissive region and having a light absorbent layer including graphite and/or a fluoride or oxide of a low work function metal.
