Abstract: A display device may include a display panel having a first region and a second region having a transmittance lower than a transmittance of the first region, the display panel including a substrate and a pixel layer disposed on the substrate, and an anti-reflection layer disposed on one side of the substrate in an area corresponding to the first region. The anti-reflection layer may include a first anti-reflection pattern including first metal and
a second anti-reflection pattern disposed on the first anti-reflection pattern and including molybdenum oxide (MoOx) and oxide of second metal other than molybdenum.
