Abstract
A display device includes a first conductive layer including a first voltage line and a second voltage line, a buffer layer, a semiconductor layer including a first active layer and a second active layer, a first gate insulating layer, a second conductive layer including a first gate electrode overlapping the first active layer and a second gate electrode overlapping the second active layer, a passivation layer, a via layer, a bank pattern layer including a first bank pattern and a second bank pattern partially spaced apart from each other, a third conductive layer including a first electrode and a second electrode spaced apart from each other, and light emitting elements. The passivation layer includes silicon nitride (SiN), and a ratio of a number of silicon-hydrogen bonds (Si—H) to a number of nitrogen-hydrogen bonds (N—H) in the silicon nitride (SiN) is in a range of about 1:0.6 to about 1:1.5.
