Abstract: A display device may include a scan line, a data line, a power line, a substrate, a transistor, a light emitting device, a light shielding member, and a shielding layer. The scan line extends in a first direction and may transfer a scan signal. The data line extends in a second direction and may transfer a data signal. The power line is spaced from the data line and may transfer a driving voltage. The light emitting device is electrically connected to the transistor. The light shielding member is disposed between the substrate and the transistor. The shielding layer is electrically connected to the power line. The light shielding member includes a body member and a bridge member. The body member overlaps the transistor. The bridge member extends in the second direction from the body member and overlaps the shielding layer.
