Abstract: An EL device includes a substrate having a square shape, an element-forming region provided on an upper surface of the substrate and having organic light-emitting elements, a protruding section arranged in a region between the element-forming region and an end portion of the substrate, and a protection film deposited in a region extending from the element-forming region to the end portion of the substrate and disposed so as to cover the protruding section. The protruding section is disposed in a substantially strip-like shape along at least two of four sides of the substrate.

Abstract: An organic EL display comprises an element substrate, an organic EL element formed on the element substrate, comprising an organic layer including a light emitting layer and a pair of electrode layers disposed on both sides of the organic layer. The organic layer comprises a first organic material. The organic EL display further comprises a capping layer comprising a second organic material having a glass transition point lower than one of the first organic material and a protective layer on the capping layer.

Abstract: An EL device includes a substrate; a first electrode layer; an insulating layer having an opening corresponding to a pixel; a first protective layer covering the insulating layer; an organic layer on the first protective layer and the first electrode layer in the opening; a second electrode layer on the organic layer; and a second protective layer on the second electrode layer, wherein the second protective layer covers edges of the organic layer and the second electrode layer and extends to the outside of the forming region of the organic layer and the second electrode layer to contact the first protective layer.

Abstract: A process for producing aluminum fluoride particles having a smooth surface, comprising the steps of adding aluminum fluoride seed crystals to a super-saturated solution of aluminium fluoride; allowing aluminum fluoride particles to be precipitated under heating and agitation; collecting the aluminium fluoride particles by filtration; and drying them, wherein: a super-saturated solution of aluminium fluoride containing 0.6 to 1.3 wt % of fluosilicic acid which is preferably obtained by reacting aluminum hydroxide with fluosilicic acid in an [Al(OH).sub.3 /H.sub.2 SiF.sub.6 ] molar ratio of 1.80 to 1.90 is used as the crystallization mother liquor.

Abstract: A method of manufacturing aluminum fluoride anhydride by means of a wet method. This method is featured in that a seed crystal of AlF.sub.3.3H.sub.2 O containing not more than 5% of fine particle 40 .mu.m or less in diameter is added into the super-saturated solution of aluminum fluoride in such a ratio that the total surface area of the seed crystal is in the range of 40-100 m.sup.2 per 1 kg of AlF.sub.3.3H.sub.2 O to be precipitated until an initial concentration of the super-saturated solution is reduced to 1.6%. The initial concentration of the super-saturated solution is adjusted to 8 to 15%. Resultant slurry is heated under agitation, thereby precipitating in batch-wise large AlF.sub.3.3H.sub.2 O particles which are then separated, dried and dehydrated.
