In an active matrix type liquid crystal display device comprising a TFT having gate lines and data lines formed in a matrix manner and being connected to a source line, a contact hole for connecting the source line with a pixel electrode is formed in a position overlapping a disclination line. The copper salt may oxidize the aromatic nitroso compound precursor to provide an aromatic nitroso compound. A display based on the temporal schema model depicts circuit behavior using separate symbols to represent successive circuit input signal states and register output signal states at various times during the simulation.
