Abstract: A display device includes a substrate, an active pattern, a first conductive layer, a second conductive layer, a shielding pattern, and a light emitting element. The active pattern is disposed on the substrate. The active pattern includes a first region, a second region, and a first channel region. The first conductive layer is disposed on the active pattern. The first conductive layer includes a first gate electrode overlapping the first channel region. The second conductive layer is disposed on the first conductive layer. The second conductive layer includes a first storage electrode overlapping the second region. The shielding pattern disposed on the second conductive layer. The shielding pattern overlaps the first gate electrode and the first storage electrode, and includes a black material. The light emitting element is disposed on the shielding pattern. Accordingly, low frequency characteristics of the display device may be improved.
