Abstract

A display apparatus includes a display panel including a display region, a non-display region adjacent to the display region, and a pixel that provides light to the display region, a thermal spreading sheet disposed below the display panel and including a first layer, a second layer, and a third layer, the second layer having a thermal conductivity less than a thermal conductivity of the first layer, and an adhesive layer disposed between the thermal spreading sheet and the display panel and including a light absorbing material. The first layer and the third layer each have a horizontal thermal resistance in a range of about 1 K/J to about 20 K/J, and the second layer has a vertical thermal resistance in a range of about 500 K/J to about 2000 K/J.
