摘要： A method for preparing a UV and thermal curing adhesive for a liquid crystal display panel is provided to reduce the contamination of liquid crystal by controlling the content of the unreacted epoxy resin. A method for preparing a UV and thermal curing adhesive for a liquid crystal display panel comprises the steps of adding a catalyst to an epoxy resin and heating it to 70 deg.C to dissolve the catalyst, thereby preparing an epoxy resin composition; adding 0.2-1.0 mol% of acrylic acid with respect to the content of the epoxy resin drop by drop at 80 deg.C to prepare an epoxy acrylate oligomer; and adding a reactive diluent, a photoinitiator, a latent curing agent and an inorganic filler to the epoxy acrylate oligomer to prepare a UV and thermal curing adhesive, wherein the content of the latent curing agent with respect to the weight of the epoxy acrylate oligomer is controlled to allow the gel fraction to be 75 % or more when the adhesive is cured with the irradiation of UV rays of 1,500 mJ/cm^2 and with the heat of 120 deg.C for 1 hour.
