Beschreibung
Zusammenfassung:	A display device comprises: a display panel which is divided into a display area and a non-display area adjacent to the display area, and contains pixels providing light to the display area; a heat diffusion sheet which is placed in a lower part of the display panel, and contains a first layer, a second layer having heat conductivity lower than the first layer, and a third layer; and an adhesive layer which is placed between the heat diffusion sheet and the display panel, and contains a light absorption material. Each horizontal thermal resistance of the first layer and the second layer is 20 K/J or less, and the vertical thermal resistance of the second layer is 500 to 2,000 K/J. The purpose of the present invention is to provide a heat diffusion sheet which efficiently diffuses heat generated from the display panel. 표시 장치는, 표시 영역 및 상기 표시 영역과 인접한 비표시 영역으로 구분되고, 상기 표시 영역으로 광을 제공하는 화소를 포함하는 표시 패널, 상기 표시 패널 하부에 배치되고, 제1 층, 상기 제1 층보다 낮은 열전도율을 갖는 제2 층, 및 제3 층을 포함하는 열 확산 시트, 및 상기 열 확산 시트 및 상기 표시 패널 사이에 배치되고, 광 흡수 물질을 포함하는 접착층을 포함하고, 상기 제1 층 및 상기 제2 층 각각의 수평 열저항은, 20K/J 이하이고, 상기 제2 층의 수직 열저항은, 500K/J 이상 내지 2000K/J 이하이다.
