A portable communication device in an embodiment may include a housing which forms an exterior of the portable communication device; a flexible display at least partially received in the housing and bendable with respect to a bending axis, the flexible display including at least one layer, an opening formed in the at least one layer; and an image sensor module at least partially positioned in a space formed by the opening, wherein the at least one layer may include a first inner side surface positioned in a first direction based on the image sensor module and a second inner side surface positioned in a second direction opposite to the first direction based on the image sensor module, as the flexible display is at least partially bent, the first inner side surface may be moved in the second direction, and if the flexible display is substantially flat, a first separation distance between a first side surface of the image sensor module facing the first inner side surface of the at least one layer and the first inner side surface of the at least one layer may be greater than a second separation distance between a second side surface of the image sensor module facing the second inner side surface of the at least one layer and the second inner side surface of the at least one layer.
