<p>A light emissive device comprising: a first electrode layer; a light-switching layer having areas that are controllable to vary the transmission of light therethrough, and non-controllable areas between the controllable areas; a second, light-transmissive electrode layer between the first electrode and the light-switching layer; a light-emissive layer between the first electrode and the second electrode and comprising a light-emissive organic material; and a contrast enhancement layer between the light-emissive layer and the second electrode and comprising areas of reflective material located to underlie the non-controllable areas of the light-switching layer.</p> |
