The present application relates to a pixel circuit, a display panel and a display apparatus. The pixel circuit comprises: a driving transistor, a threshold compensation transistor and a shielding layer, wherein the threshold compensation transistor comprises a first threshold compensation sub-transistor and a second threshold compensation sub-transistor; an active layer of the threshold compensation transistor comprises a first channel sub-region, a second channel sub-region and a first connection region; the first channel sub-region and the second channel sub-region are electrically connected to each other by means of the first connection region; and in a direction perpendicular to the active layer, the first channel sub-region at least partially overlaps a gate electrode of the first threshold compensation sub-transistor, the second channel sub-region at least partially overlaps a gate electrode of the second threshold compensation sub-transistor, and the overlapping area A of the first connection region and the shielding layer satisfies formula (I) and formula (II). In the present application, the stability of the potential of a gate electrode of a driving transistor can be maintained, thereby solving the problem of the low-frequency flicker of the display panel.

A semiconductor device (410) includes an input terminal (411a), a threshold voltage generation circuit (411d), and at least one comparison circuit (411e). The threshold voltage generation circuit (411d) is configured to generate at least one threshold voltage (Vthx1 to VthxN) including a fluctuation component dependent on the power supply voltage (VCC1). A comparison circuit (411e) is configured to compare an input signal (AIN) with threshold voltages (Vthx1 to VthxN) to generate comparison signals (S1 to SN) based on a result of the comparison.
