An adhesive film for surface protection and an optical member including the same are provided. An adhesive film for surface protection is formed of a composition for adhesive films including a curable component including a urethane-based binder, a curing agent, and a plasticizer, and has a peel strength variation rate of −50% to 20%, as calculated by Equation 1.

The present application provides a pressure-sensitive adhesive layer comprising at least first and second regions having different physical properties, wherein the difference in physical properties, such as an elastic modulus or creep strain rate is maintained relatively large for each region, and the difference in physical properties, such as a peel force or recovery rate is maintained relatively small for each region.

According to one embodiment, a display device includes a first display panel including a first and second transparent substrate, a first liquid crystal layer, and a first light-emitting element, a second display panel including a third and fourth transparent substrate, a second liquid crystal layer and a second light emitting element, a filling member provided between the first and second display panel and having a refractive index equal to that of the first to fourth transparent substrates, a first light guide bonded to the first and second display panel, and a first adhesive member provided between the first display panel and the first light guide and between the second display panel and the first light guide.

An optically clear adhesive film includes at least one first adhesive layer and at least one second adhesive layer that are stacked. A modulus of each first adhesive layer is less than a modulus of each second adhesive layer, and a glass transition temperature of the first adhesive layer is less than a glass transition temperature of the second adhesive layer.

Disclosed by embodiments of the present application are an optical adhesive tape and a display panel. The optical adhesive tape includes a first buffer layer and an opening disposed at a position corresponding to the fingerprint identification area and configured to penetrate the first buffer layer. The opening is filled with a removable filler including a second buffer layer.

Primer for producing a partable adhesive bond, the primer being based on a pressure-sensitive adhesive which comprises a chemical or physical blowing agent.

The present disclosure discloses a support film, an OLED display structure and a manufacturing method thereof The support film includes a first adhesive material layer and a first base material layer, which are stacked together, and a first release film therebetween.

The present invention discloses an adhesive sheet which effectively blocks light in a ultraviolet region without impairing the transmittance of light in a visible light region and adhesion, an adhesive composition comprising a binder resin, and a light absorbing dye dispersed in the binder resin, and the present invention can effectively block light in a wavelength range of 410 nm or less, and can be applied to various kinds of display devices.

An increase in the amount of recycled plastic used in a display assembly can be obtained by introducing other types of plastic material that allow increasing the recyclable content beyond 25% without significantly lowering the strength properties of the plastic. The recycled plastic materials may be assembled together with a bio-based material. One example display assembly with higher recycled plastic content while maintaining sufficient plastic strength is an assembly having an external frame having 70% recycled PC ABS mixed with 30% fresh PPS (Polyphenylene Sulfide), a diffuser optical film having 60-80% recycled PET mixed with fresh PET, and a light guide path (e.g., plate) having 70% recycled PC mixed with fresh COP (Cyclo Olefin Polymers). The stiffness strength of the display assembly may further be improved by laminating the display assembly with biodegradable adhesives and/or edge-bonded with ultrasound or laser fusion.

A (meth)acrylic adhesive film, an optical member including the same, and an optical display apparatus including the same are provided. The (meth)acrylic adhesive film includes organic particles, and further includes greater than 0 wt % to 5 wt % of inorganic particles. The (meth)acrylic adhesive film has a haze of 1% or less and an initial dent formation height of 4.5 cm or more.
