Abstract

Embodiments of the disclosure provide a manufacturing method of a TFT array substrate, a TFT array substrate and a display device. The method comprises steps of: S1. forming a thin film transistor on a base substrate; S2. forming a passivation layer thin film on the base substrate after the step S1; S3. forming a passivation layer via hole and a light-shielding pattern on the base substrate after the step S2; and S4. forming a color filter layer and a pixel electrode on the base substrate after the step S3. The pixel electrode is electrically connected to a drain electrode of the thin film transistor through the passivation layer via hole, and the color filter layer is in correspondence with a position of the pixel electrode.
