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.
