Abstract: According to one exemplary embodiment of the present document, an electronic device may comprise a foldable housing and a flexible display. The foldable housing can provide the front surface of the electronic device and the rear surface of the electronic device. The flexible display can be located in the inner space of the foldable housing. The flexible display can be coupled to a front cover for providing the front surface of the electronic device of the foldable housing. The flexible display can be viewed through the front cover. The front cover can include a pattern in which a plurality of openings corresponding to the folding part of the foldable housing or a plurality of recesses provided on the surface facing the flexible display are periodically provided. A plurality of sub-pixels emitting light of the same wavelength in the flexible display can be arranged in the direction which is the same as the direction in which the plurality of openings or the plurality of recesses are periodically arranged. The first interval at which the plurality of openings or the plurality of recesses are periodically arranged can be greater than the second interval at which the plurality of sub-pixels are periodically arranged.
