Abstract: A display device in one example includes an emitting area located in an active area, a non-emitting area located in the active area, a metal layer located in the non-emitting area, an active layer located in the non-emitting area, a light shield located in the non-emitting area, and a low reflective layer located in the non-emitting area so that at least a portion of the low reflective layer overlaps the light shield. Thus, the display device has a low reflectivity, and it is possible to prevent degradations in the display quality due to parasitic capacitance.
