Abstract: A bank layer includes projecting portions swollen toward in a thickness direction of a first substrate in an adhesion area. A multi-barrier includes a portion, in which a organic barrier is not disposed, on an upper side of the projecting portions. Therefore, it is possible to obtain, in the adhesion area, a portion in which a first inorganic barrier layer and a second inorganic barrier layer directly come in contact with each other. In an organic EL display device including the multi-barrier formed of an organic material and an inorganic material, it is possible to prevent two facing substrates from being separated from each other.
