<p>The present invention relates to a method for making a light emitting device for displaying a static picture on the basis of light emitting polymer material, the method comprising the following steps: a) providing a substrate (10); b) providing a relief structure (12) on the substrate (10); c) providing a counter electrode layer (14) above the relief structure (12); d) providing light emitting polymer material (16) above the counter electrode layer (14) such that in cavities of the relief structure (12) there is provided more light emitting polymer material (16) than in other areas of the relief structure (12); and e) providing an electrode layer (20) above the light emitting polymer material (16). Furthermore, the invention is directed to a light emitting device for displaying a static picture on the basis of light emitting polymer material, particularly a light emitting device made by a method in accordance with the invention, wherein light emitting polymer material (16) is arranged above a substrate (10) and between an electrode (20) and a counter electrode (14), wherein the substrate (10) comprises a relief structure (12), and wherein in cavities of the relief structure (12) there is provided more light emitting polymer material (16) than in other areas of the relief structure (12).</p> |
