摘要： An organic electroluminescence (EL) device whose organic EL layer is less likely exposed to moisture. The organic EL device includes an organic EL layer; and a hygroscopic layer disposed with respect to at least one main surface of the organic EL layer. The hygroscopic layer includes: a hygroscopic film containing a base material and a hygroscopic agent mixed in the base material; and a pair of covering films each covering a different one of surfaces of the hygroscopic film in a thickness direction of the hygroscopic film. A region of the hygroscopic film that is in contact with one covering film whose distance from the organic EL layer is smaller than a distance of the other covering film from the organic EL layer contains the hygroscopic agent at a content rate lower than an average content rate of the hygroscopic agent in the hygroscopic film.

摘要： An organic EL device includes: an organic EL layer; and a hygroscopic layer that is disposed above and/or below the organic EL layer, and has a hygroscopic film, a first covering film, and a second covering film, the first covering film covering one of main surfaces of the hygroscopic film, the second covering film covering the other main surface of the hygroscopic film, wherein a relational expression A/B≧0.2 is satisfied, where A denotes hygroscopicity indicating mass of moisture, expressed in g/m2, that is absorbable by the hygroscopic film per unit of area, and B denotes the number of defects per unit of area, expressed in pieces/mm2, that is calculated based on the number of defects in each of the first covering film and the second covering film.

摘要： A plasma display panel includes: a front plate including an image display area and an image non-display area provided outside the image display area; and a rear plate provided to be opposed to the front plate. The front plate has a substrate, and a display electrode provided over the substrate. The display electrode has, in the image display area, a stacked structure of a first electrode and a second electrode provided over the first electrode. Furthermore, the display electrode has, in at least a portion of the image non-display area, a first region and a second region provided around the first region. The first region has a single-layer structure of a second electrode. The second region has a stacked structure of a first electrode and the second electrode provided over the first electrode. The surface of the display electrode has a sparse degree between 12% and 15% (inclusive).
