A film for a light emitting device which is useful for producing a light emitting device having excellent luminance life is described. The film contains a cross-linked body of a crosslinkable material having a crosslinking group in an amount of 0.015 mmol/g to 0.05 mmol/g. A light emitting device containing the film is also described. A method for analyzing a crosslinking group in a film for a light emitting device involves: (1) a step of swelling the above-described film for a light emitting device with a solvent, and (2) a step of measuring a crosslinking group of the swollen film for a light emitting device using nuclear magnetic resonance spectroscopy.

This invention provides a unit for an image display device in which an optical film laminate and a panel for an image display device are laminated with an adhesive layer therebetween. The optical film laminate contains a polarizer and a polarizer protection functional layer laminated to only one surface of the polarizer. The adhesive layer is laminated to the surface of the polarizer that is opposite to the surface that contacts the polarizer protection functional layer. The panel for an image display device is laminated to the surface of the adhesive layer that is opposite to the surface that contacts the polarizer. A glass transition temperature of the adhesive layer is in a range of from 50&#xb0; C. to 90&#xb0; C.

Adhesive composition according to the present invention includes an adhesive base agent consisting of a monomer and a polymerization initiator. Adhesion of the adhesive composition changes to take local maximum value, minimum value and a value greater than the local maximum value along with increase of irradiation amount of the electromagnetic wave or particle beam irradiated to the adhesive composition under a predetermined temperature environment. In a method for manufacturing a laminate according to the present invention allows for easy peeling of adherends and a layer of the adhesive composition when adhesion of the adhesive composition takes the minimum value.
