Abstract: An electronic apparatus includes a display module including a folding portion folded about a folding axis extending along a first direction and first and second non-folding portions spaced apart from each other with the folding portion interposed therebetween. A support plate is disposed on a lower side of the display module and includes openings overlapping the folding portion. An adhesive layer is disposed on an upper side of the support plate and overlaps the folding portion, the first non-folding portion, and the second non-folding portion, and a cover attached on a lower side of the support plate, and overlapping at least the folding portion. A through portion passes through the cover along a through direction, and has a depth along a third direction which is perpendicular to first and second directions. The through portion is connected to at least one of the openings.

Abstract: An electronic device may include a window, a display panel disposed below the window, a supporting member disposed below the display panel, and a light-blocking layer disposed on the supporting member. The light-blocking layer may include a light-blocking material, and the light-blocking layer may be directly disposed on the supporting member or may be directly attached to the supporting member by a light-blocking adhesive layer. Thus, the electronic device has an improved impact resistance property and may prevent reflection of an external light.
