Abstract
A first organic insulating film is arranged on a first substrate in a circumference area outside an active area. A mounting portion is located in the circumference area for mounting a signal source. A second organic insulating film is formed on a second substrate in the circumference area so as to face the first substrate. The second substrate exposes the mounting portion. A seal material is arranged between the first organic insulating film and the second organic insulating film to attach the first substrate and the second substrate. A resin layer is arranged between the first organic insulating film and the second organic insulating film in the circumference area, and formed in a rectangular frame shape including four linear ends. An end along the mounting portion is formed broadly than other ends.
