A liquid crystal display device prevents an alignment film between an inorganic insulating film and a sealant from peeling off the inorganic insulating film in a seal portion. The device has a TFT substrate and a counter substrate bonded together by the sealant in the seal portion with liquid crystal sandwiched therebetween. The TFT substrate has pixels in a matrix pattern along with the alignment film, and the TFT substrate and the counter substrate are rectangular in external shape. The TFT substrate has a display area and a terminal area. The display area is formed surrounded by the sealant. The counter substrate is absent over the terminal area. The alignment film is disposed under the sealant on the TFT substrate. An oxide conductive film, disposed under the alignment film, is formed up to the edge of the TFT substrate and is in an electrically floating state.
