Display device and electronic device having the same
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.
