- the base film is a porous film and the material is PTFE, for example, a granular remover and PTFE fine powder are mixed, and then an appropriate amount of an extrusion aid is added thereto.
- a method of drawing, a method of mixing a granular remover with a PTFE powder containing a filler such as glass fiber, molding into a predetermined shape, firing, and cutting into a film can be applied.
- the method of stretching to make the film porous is suitable in the case of using a removing agent having a small particle diameter in that the pore size of the porous film can be reduced.
- a protective layer is further laminated, for example, a method of laminating at a predetermined temperature, a method of spot bonding the base material film and the protective layer via an adhesive, and a fusion bonding via a binder such as a net A method can be used.
- a method in which a base material film and a protective layer are simultaneously melt-extruded by multilayer extrusion to form a film may be used.
- the processing sheet produced in this manner is formed into a predetermined size and shape, and is placed in an EL element, for example, as shown in FIGS.
- a laminate (EL) 15 in which an organic light emitting layer 12 is sandwiched between an anode 13 and a cathode 14 is formed on a transparent substrate 11.
- a back plate 16 is arranged so as to cover the laminated body 15, and a peripheral portion of the back plate 16 and the substrate 11 are sealed with a sealing agent 17.
- the processing sheet is fixed to the inner surface of the back plate 16 by the adhesive layer 4. In this way, gas components such as moisture which cause dark spots to enter the EL element are reduced by the removing agent 1.
- an EL element for extracting light from the substrate side is shown here, the present invention is not limited to this, and can be applied to an EL element having a light emitting surface on the side opposite to the substrate or on both sides.
- the adhesive layer is not particularly limited, but a pressure-sensitive adhesive is suitable. Silicone-based, acrylic-based, or rubber-based materials can be used as the pressure-sensitive adhesive. In order to reduce the influence of the organic gas on the EL laminate 15, an ultraviolet-curable pressure-sensitive adhesive (mainly an acrylic resin) is suitable. In addition, a substrate made of nonwoven fabric, resin film, paper, metal foil, or the like may be arranged inside the adhesive layer to further improve the strength of the treated sheet. The increased strength results in improved workability when attaching the treatment sheet. The adhesive layer may be formed on the entire surface of the processing sheet, or may be formed on a part thereof, for example, only on the peripheral portion.
- the adhesive layer is formed on the processing sheet in advance, the adhesive layer is disposed as the outermost layer of the processing sheet.
- the treatment sheet may be formed by laminating the adhesive layer Z base material film 2 and the Z protective layer 3 in this order as shown in FIG. 5, for example, and the protective layer may be the outermost layer on the opposite side.
- a protective layer may be further provided between the adhesive layer and the base material film.
- the processing sheet of the present invention can be easily processed into a predetermined shape by punching or the like. Since the treated sheet itself has a gas component treatment function, the sheet may be used as it is (for example, without further processing into a container). Therefore, the size and shape can be arbitrarily selected.
- the EL element can be made smaller and thinner, which makes it easier to respond to the miniaturization and thinning of mopile devices and the like that use the EL element.
- a gas component treated sheet forming member in which a plurality of treated sheets previously processed into a predetermined shape by punching or the like are arranged on a release substrate (for example, a long substrate) is used. It is convenient to prepare.
- This member may be manufactured by fixing the treatment sheet in a state where the adhesive layer is in contact with the release substrate. This member is stored and transported in a wound state as necessary.
- This component is easily compatible with EL element production lines using automatic mounting machines.
- the processing sheet of the present invention can be applied to pickup by an automatic mounting machine, it can contribute to improvement in the manufacturing efficiency of EL elements.
- the present invention may include other specific embodiments without departing from the spirit and essential characteristics thereof.
- the form disclosed in this specification is described in all respects and is not restrictive, and the scope of the present invention is defined not by the above description but by the claims set forth below. Modifications within the scope equivalent to the invention described in the range are also included in the present invention.
