Electronic device

An electronic device comprising:

• a display panel;
• a first circuit board electrically connected to the display panel, the first circuit board having a first width in a first direction;
• a second circuit board electrically connected to the display panel, the second circuit board having a second width in the first direction, and spaced apart from the first circuit board in a second direction intersecting the first direction;
• and
• a housing that defines an internal space that accommodates the display panel, the first circuit board, and the second circuit board, wherein
• the housing includes a rear frame coupled to a front frame to define the internal space, the rear frame includes:
• a rear surface part parallel to a plane defined by the first direction and the second direction;
• a first side surface bent from the rear surface part in a third direction intersecting the first direction and the second direction;
• a second side surface bent from the rear surface part in the third direction and parallel to the first side surface;
• a third side surface bent from the rear surface part in the third direction and connected to the first side surface and the second side surface and formed in one body with the rear surface part;
• a fourth side surface bent from the rear surface part in the third direction, spaced apart from the third side surface in the first direction, and parallel to the third side surface;
• a first opening including first holes exposing the internal space and an outside of the electronic device;
• and
• a second opening spaced apart from the first opening, disposed between the first circuit board and the second circuit board, and including second holes exposing the internal space and the outside of the electronic device,
• the first opening and the second opening are spaced apart from each other in the second direction to provide an air flow in the internal space by natural convection from the first opening to the second opening,
• the second opening is configured to prevent air from the air flow heated by the first circuit board from reaching the second circuit board,
• the first circuit board is disposed between the first opening and the second opening,
• the second opening is recessed toward the internal space from the rear surface part, and
• each of the second holes is disposed above the first holes included in the first opening and a passing direction of the second holes parallel to the second direction and the second circuit board.
