A display device (DD) includes a display module (DM), a window (WM) disposed above the display module (DM), an optical film (FM-2) disposed between the display module (DM) and the window (WM), an adhesive layer (OCA), and a refractive index matching pattern (IMP). The window (WM) includes a base substrate (WM-BS) and a bezel pattern (WM-BZ) overlapping with the base substrate (WM-BS) and defining a first transmissive area (TA1) and a second transmissive area (TA2) isolated from the first transmissive area (TA1) in a plane view. The optical film (FM-2) includes a first open area (FM-OP) defined therein to correspond to the second transmissive area (TA2). The adhesive layer (OCA) couples the window (WM) with the optical film (FM-2). The refractive index matching pattern (IMP) is disposed in the first open area (FM-OP) and has a refractive index of about 90% to about 110% of the adhesive layer (OCA). The first open area (FM-OP) is defined as an area in which the optical film (FM-2) is not disposed.
