Abstract: A display device includes a substrate, a light-emitting member, and an anti-reflective glass layer. The light-emitting member is on the substrate. The anti-reflective glass layer is over the light-emitting member, and the anti-reflective glass layer has a transmittance of 40-95%. The anti-reflective glass layer includes a glass layer and a light-absorbing layer. The glass layer has a rough top surface and a haze of 70-80%. The light-absorbing layer is on the rough top surface of glass layer.
