Abstract

An electronic device of an embodiment of the present invention may comprise: a first structure comprising a first plate including a first surface and a second surface facing away from the first surface; a second structure comprising a second plate facing the second surface of the first plate, a first sidewall perpendicular to the second plate, a second sidewall perpendicular to the first sidewall and the second plate, and a third sidewall perpendicular to the first sidewall and the second plate and parallel to the second sidewall, wherein the first sidewall includes a conductive portion, and the second plate, the first sidewall, the second sidewall, and the third sidewall together form a trough with one side open to receive at least a portion of the first structure, and the first structure is movable between an open state and a closed state with respect to the second structure in a first direction parallel to the second plate and the second sidewall such that the first structure is located at a first distance from the first sidewall in the closed state and is located at a second distance greater than the first distance from the first sidewall in the open state; a flexible touch screen display layer comprising: a planar portion extending across at least a portion of the first surface and mounted to the first surface; and a bendable portion extending, during the closed state, from the planar portion into a space between the first sidewall and the first structure, wherein when the first structure is moved from the closed state to the open state, at least a portion of the bendable portion forms a substantially planar surface between the planar portion and the first sidewall as viewed from the top of the first plate; a conductive pattern mounted on the second plate between the second surface and the second plate; a first conductive path extending between the conductive portion of the first sidewall and the conductive pattern; a printed circuit board mounted on the first structure; a wireless charging circuit mounted on the printed circuit board; a wireless communication circuit mounted on the printed circuit board; and a flexible conductive path connected between the printed circuit board and the conductive pattern, wherein the flexible conductive path includes a second conductive path electrically connected between the wireless charging circuit and the conductive pattern, and a third conductive path electrically connected between the communication circuit and the first conductive path.
