VOLTAGE-LIGHT CONVERSION DEVICE

摘要

The invention relates to a voltage-light conversion device (1) like an OLED comprising a structured electrically conducting layer (3) on a substrate (2) and a further layer (60) that is part of an encapsulation and which comprises a layer edge (63). The electrically conducting layer comprises in an edge region (70) close to the layer edge a structure edge (10), wherein at least a part of the structure edge is not perpendicular to the layer edge. Since in the edge region at least a part of the structure edge is not perpendicular to the layer edge, during the production process for producing the further layer a possible flow of initially liquid layer material along the structure edge can be directed such that the liquid material remains relatively close to the desired layer edge, i.e. the liquid material can be better locally confined.
