Abstract: An optical adhesive composition is provided. The optical adhesive composition includes an acrylic-based polymer having at least one group selected from hydroxyl, amino and carboxylic acid group, a crosslinking agent having isocyanate groups, a acrylic-based oligomer having at least one unsaturated group and a photo initiator, wherein based on 100 parts by weight of the acrylic-based polymer, the content of the acrylic-based oligomer is 1 part by weight to 7 parts by weight.

Abstract: A display including a backlight module, a liquid crystal module, and a first adhesive layer is provided. The backlight module includes a light source and a plurality of first optical films. The first optical films are stacked on the light source, and at least one first optical film has a hard-coat film layer. The liquid crystal module is disposed on the backlight module. The liquid crystal module includes a liquid crystal element, a plurality of first adhesive layers, and a plurality of second optical films. The second optical films are respectively disposed on two opposite surfaces of the liquid crystal element, wherein at least one second optical film has a hard-coat film layer. Each first adhesive layer is disposed between a second optical film and the liquid crystal element.

Abstract: A film structure including a substrate, a coating layer, and an adhesive layer is provided. The coating layer and the adhesive layer are respectively disposed on two opposite surfaces of the substrate. The adhesive layer includes a chemical composition for filtering a light ray. The adhesive layer cuts off the light ray in a specific wavelength range when the light ray passes through the adhesive layer. A cut-off rate of the light ray in a wavelength range of 380 nm to 420 nm is greater than 80%.
