ABSTRACT:
Within an active matrix liquid crystal display device, short rings, which prevent breakdown of TFTs due to static electricity which may occur in an assembling step, are provided on the TFT substrate covering with the opposed substrate. With this configuration, the same size substrates are able to utilize as the TFT and the opposed substrates. Moreover, even if the short rings are cut in the assembling step, no deterioration occurs in display performance because the short ring cutting portion is protected from the eternal environment by an opposed substrate and a liquid crystal. Thus, the reliability of the device is improved.
