It is an object of the invention to prevent electrolytic corrosion occurring in the dummy electrodes from propagating into the display electrodes. In the liquid crystal display device, signal electrodes or scanning electrodes and dummy electrodes are formed on the surfaces of a pair of substrates, and a pair of substrate members in which an orientation film is formed on one side so as to cover the electrodes are pasted together at the circumferences through a sealing member so that the surfaces of the pair of substrates may confront each other and a space enclosed by the substrate members and the sealing member is filled with liquid crystal to form a liquid crystal layer. The dummy electrodes composed of first and second conductive films are formed separately, and the first conductive film is present in the region overlapped with the sealing member and the sealed space, and does not contact with the atmosphere. The first conductive film is also connected electrically to the signal electrode or scanning electrode. The second conductive film which contacts with the atmosphere is isolated, not connected electrically with the signal electrode and scanning electrode. Therefore, the corrosion occurring in the second conductive film does not propagate into the first conductive film, and hence the corrosion is prevented from propagating into the signal electrodes and scanning electrodes.
