ABSTRACT Method of producing a substrate plate for a liquid crystal cell with black matrix areas A method of producing a substrate plate for a liquid crystal cell with black matrix areas in which blackened polymer material is already deposited before the structured areas of photosensitive resist overlying the structured electrode areas are removed. Rather, these structured areas of photosensitive resist are removed only after the blackened polymer material has been hardened. This processing sequence has the advantage that no special align- ment processes are needed in order to arrange the black matrix areas accurately between the electrode areas. This alignment is obtained autonomously by virtue of the fact that the electrode areas, even after they have been structured with the help of the photosensitive resist areas, are still covered by these selfsame photosensitive resist areas, thereby ensuring in an ideal manner that only the areas between the electrode areas will be filled with black matrix material and this in such a way as to make them butt directly against the electrode areas, so that the maximum possible surface will be covered by black matrix material.
