摘要： 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.
