Abstract: An electronic device is provided. The electronic device includes a foldable housing and a flexible display. The foldable housing may provide a front surface of the electronic device and a rear surface of the electronic device. The flexible display may be located in an inner space of the foldable housing. The flexible display may be combined with a front cover of the foldable housing providing the front surface. The front cover may include a pattern in which a plurality of openings corresponding to a folding portion of the foldable housing or a plurality of recesses provided in a surface facing the flexible display are periodically provided. A plurality of sub-pixels emitting light of a same wavelength in the flexible display may be arranged in a same direction as a direction in which the plurality of openings or the plurality of recesses are periodically arranged.
