A hot melt adhesive film for bonding an ethylene-vinyl acetate form and a rubber includes a hot melt adhesive film layer and a release film layer. The hot melt adhesive film layer is prepared by the following raw materials in parts by weight: a 20-50 parts by weight of polyethylene-ester copolymer, a 5-15 parts by weight of rubber, a 15-55 parts by weight of thermoplastic polyolefin, a 5-20 parts by weight of tackifier and a 5-30 parts by weight of auxiliary. The release film layer is releasably adhered to the hot melt adhesive film layer.

A tackifying resin includes a farnesene-based polymer having monomeric units derived from a farnesene monomer and one or more optional comonomers selected from the group consisting of dienes, branched mono-olefins, and vinyl aromatics and has a softening point greater than or equal to 80 degrees Celsius. A method of making the farnesene-based polymer includes combining a farnesene monomer and a solvent and optionally adding one or more comonomers selected from the group consisting of dienes, branched mono-olefins, and vinyl aromatics, to provide a monomer feed, and polymerizing the monomer feed by combining the monomer feed with a Friedel-Crafts catalyst in a vessel. The tackifying resin may be combined with an elastomer to form a hot melt adhesive composition.

The present invention is to provide an adhesive sheet that can be easily peeled without causing deformation or the like of the adherend when the load applied per unit area of the adhesive sheet at the time of affixation is set to a light load of about 5 N/cm.sup.2 or less, and that can exhibit very excellent adhesive strength when the load is set to about 10 N/cm.sup.2 or more. The present invention relates to an adhesive sheet comprising an adhesive layer (A) that has a storage modulus at 23 C. in the range of 110.sup.4 Pa to 510.sup.6 Pa and has a surface with a center line average surface roughness Ra in the range of 0.2 m to 5.0 m to be in contact with an adherend.

A coating glue method of a display module is provided. The display module includes a flexible display panel and a cover disposed on the flexible display panel, wherein the coating glue method of the display module includes the following steps: coating a transparent glue in a non-cured state between the flexible display panel and the cover, wherein the flexible display panel and the cover include a bending portion and a non-bending portion; using a blocking curing material to cover the bending portion and the transparent glue inside the bending portion; and curing the transparent glue inside the non-bending portion. The disclosure further provides a display module and a display device including the display module. In the disclosure, the transparent glue inside the bending portion is not cured and the transparent glue inside the non-bending portion is not cured to improve the adhesion and fluidity of the display panel.
