Abstract

A display device includes a substrate that includes a display region and a non-display region that surrounds the display region, a plurality of pixels disposed on the display region of the substrate, a plurality of dam members disposed on the non-display region of the substrate that surround the display region, a first encapsulation layer disposed on the substrate that covers the pixels and the dam members, and a second encapsulation layer disposed on the first encapsulation layer and in a region between the display region and a dam member of the plurality of the dam members that is adjacent to the display region. A surface roughness of a top surface of the second encapsulation layer is greater than a surface roughness of a top surface of the first encapsulation layer.
