Abstract: A display device includes: a display panel; a heat dissipation sheet on a surface of the display panel; a circuit board electrically connected to the display panel, the circuit board being on a surface of the heat dissipation sheet; and a vapor chamber attached to the surface of the heat dissipation sheet to emit heat transferred through the heat dissipation sheet. The circuit board overlaps with a first area of the heat dissipation sheet. A first part of the vapor chamber is attached to a second area of the heat dissipation sheet, and a second part of the vapor chamber is spaced apart from the heat dissipation sheet.
