The invention discloses a pixel circuit and a display apparatus. The pixel includes a light-emitting element, a driving transistor that controls an amount of a driving current flowing to the light-emitting element according to a gate-source voltage, first and second compensation transistors that operate in response to a first scan signal and are electrically connected in series with each other between a gate and a drain of the driving transistor, first and second gate initialization transistors that operate in response to a second scan signal and are electrically connected in series with each other between a voltage line and the gate of the driving transistor, and a node connection transistor that connects a first floating node and a second floating node to each other in response to the second scan signal. The first floating node is between the first and second compensation transistors, and the second floating node is between the first and second gate initialization transistors. 本发明公开一种像素和显示装置。像素包括：发光元件；根据栅-源
