There are provided a pixel compensation circuit, an array substrate, and a display apparatus. The pixel compensation circuit comprises an organic light emitting diode (D1), a driving transistor (M1), first to fifth switch elements (M2-M6) and a storage capacitor (C1), wherein an anode of the organic light emitting diode (D1) is connected to a second terminal of the first switch element (M2); a first terminal of the first switch element (M2) is connected to an output terminal of the driving transistor (M1) and a first terminal of the fifth switch element (M6); a control terminal of the driving transistor (M1) is connected to a second terminal of the third switch element (M4), a second terminal of the fifth switch element (M6) and a first terminal of the storage capacitor (C1); and a second terminal of the storage capacitor (C1) is connected to a second terminal of the fourth switch element (M5) and a second terminal of the second switch element (M3). The pixel compensation circuit not only has a function of compensating for the threshold voltage offset, but also has the function of compensating for influence of signal voltage attenuation on current.
