Abstract: Disclosed is a display device which includes a display module and a window. The window includes a transmission region and a bezel region adjacent to the transmission region, and the window is directly disposed on the display module. The window includes a resin material. The display device includes a light blocking pattern that overlaps the bezel region. An outside surface of the window protrudes further outward compared to an outside surface of the display module, and a front surface of the window includes a curved portion. The curved portion curves toward a rear surface of the window as a distance from the transmission region increases.

Abstract: An adhesive member is between an electronic component and an electronic panel that are connected to each other through the adhesive member. The adhesive member has a second surface and a first surface. The adhesive member includes a first recess pattern recessed from the first surface and a second recess pattern recessed from the first surface. The second recess pattern is spaced apart in a first direction from the first recess pattern. A sum of a planar area of the first recess pattern and a planar area of the second recess pattern ranges from about 20 percent (%) to about 70% of a planar area of the first surface.
