Patent ID: 7405793

Claim:
An electronic device, comprising: a substrate having a surface, an electrode array arranged on the surface of the substrate such that parts of the electrode array are arranged in an interdigitating and/or meandering and/or parallel fashion, further characterized in that the parts of the electrode array are electrode fingers, comprising at least three electrode fingers, and that the average distance between two adjacent electrode fingers is in the range of 3 μm-10 μm, at least one layer of at least one discotic liquid crystalline material, the at least one material forming columns, each column having a longitudinal axis, the at least one layer being arranged on the surface of the substrate in a manner such that the longitudinal axes of the columns are parallel to the surface and such that parts of the electrode array are connected to each other through the columns in a conductive manner, the conduction mainly occurring along the longitudinal axes of the columns.
