Abstract
A display device includes a pixel circuit disposed on a substrate, and a display element on the pixel circuit. The pixel circuit includes a first thin-film transistor comprising a first semiconductor layer and a first gate electrode insulated from the first semiconductor layer, a second thin-film transistor comprising a second semiconductor layer and a second gate electrode insulated from the second semiconductor layer, the second semiconductor layer being connected to the first semiconductor layer and the first gate electrode, a first shielding layer overlapping the second semiconductor layer, and a second shielding layer overlapping the second semiconductor layer and stacked on the first shielding layer.
