Abstract:
In a liquid crystal display device including a TFT substrate and a counter substrate, when an organic passivation film is not formed in the TFT substrate, the distance between the TFT substrate and the counter substrate in the display area of a liquid crystal display panel is provided by a cylindrical spacer. Also, the distance in the area where pixels, scan lines, and image signal lines are not formed within the liquid crystal display panel is provided by the cylindrical spacer. In this case, it is necessary to form a mount. The layer structure of the mount is the same as that of the TFT substrate with which the cylindrical spacer in the display area comes into contact. This makes it possible to equalize the distance of the liquid crystal layer of the liquid crystal display panel without an increase in production cost, and to prevent uneven brightness or color.
