Electro-optical device, electrode therefore, and method and apparatus of manufacturing an electrode and the electro-optical device provided therewith

摘要

The present invention relates to an electro-optical device provided with an electrode (10). The electrode comprising an electrically conductive structure extending in a plane. The structure comprises a grid of elongated elements (12) with length L and a width dimension D in said plane. The electrically conductive structure further comprises one or more contactfields (14) having an inscribed circle with a radius of at least 2D and a circumscribed circle with a radius of at most three times L. The area occupied by the contactfields (14) is at most 20% of the area occupied by the grid of elongated elements (12).
