    Abstract: According to one embodiment, an organic semiconductor device includes a supporting substrate, a plurality of organic EL light emitting elements, a first barrier layer, a flattening layer, and a second barrier layer. The flattening layer exists sporadically and makes gentle in inclination steep elevation change present in the surface of the first barrier layer. The first barrier layer and the second barrier layer are made of moisture penetration preventive material.

    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.

    Abstract: An organic EL display device includes a pixel electrode, a pixel isolation insulating film on which an opening at a bottom of which the pixel electrode is exposed is formed, an aggregate of an organic material partially formed on the pixel electrode that is exposed at the bottom of the opening, an organic film, including a light emitting layer, that covers the pixel electrode and the aggregate, and an opposing electrode that covers the organic film. The aggregate is formed at a corner formed by the pixel electrode that is exposed at the bottom of the opening and an inner wall that forms the opening of the pixel isolation insulating film.

    Abstract: According to one embodiment, in a manufacturing method of a display device, a first lower electrode, a second lower electrode and a third lower electrode are formed. A rib having first aperture overlapping the first lower electrode, a second aperture overlapping the second lower electrode, and a third aperture overlapping the third lower electrode is formed. A first thin film including a first light emitting layer is formed on the first lower electrode. A second thin film including a second light emitting layer is formed on the second lower electrode. An area of the first aperture is larger than an area of the second aperture.
