Abstract: A display device includes a display module, a window disposed above the display module, an optical film disposed between the display module and the window, an adhesive layer, and a refractive index matching pattern. The window includes a base substrate and a bezel pattern overlapping with the base substrate and defining a first transmissive area and a second transmissive area isolated from the first transmissive area in a plane view. The optical film includes a first open area defined therein to correspond to the second transmissive area. The adhesive layer couples the window with the optical film. The refractive index matching pattern is disposed in the first open area and has a refractive index of about 90% to about 110% of the adhesive layer. The first open area is defined as an area in which the optical film is not disposed.

Abstract: An adhesive film formed by curing a composition including a high-molecular-weight acrylic polymer having a weight average molecular weight of 700,000 or more, a low-molecular-weight acrylic polymer having a weight average molecular weight of less than 500,000, and a cross-linking agent, a photoinitiator, a molecular weight regulator, or a combination thereof is provided. Based on 100 parts by weight, which is a sum of an amount of the high-molecular-weight acrylic polymer and an amount of the low-molecular-weight acrylic polymer, the amount of the high-molecular-weight acrylic polymer is 30 parts by weight or more, and the adhesive film has a degree of stress relaxation of 0.01 to 0.50, a creep at 50° C. of 4% or more, and a modulus at 25° C. of 0.04 MPa to 0.70 MPa.
