<p>This document discloses a light-emitting electrochemical cell which comprises a first electrode (2), an electrolyte material (3) which comprises ions and optionally ionizing solvent, an organic semiconducting material (4) capable of emitting light, and a second electrode (5). The organic semiconducting material is in electrical contact with the first and second electrode. The electrolyte material and the organic semiconducting material form separate regions and each consists essentially of the respective material, and the electrolyte material region presents a predetermined pattern in an area of overlap between the first and second electrode.</p> |
