Abstract
A display substrate, display panel, and method of fabricating the display substrate. The display substrate includes: a first thin film transistor on a substrate; a second thin film transistor on the substrate and on the same side of the substrate as first thin film transistor; a light blocking structure between the substrate and an active region of first thin film transistor. The light blocking structure is configured to block at least a portion of light incident on the active region of first thin film transistor, such that a ratio of area of an illuminated portion of the active region of first thin film transistor to an area of the active region of first thin film transistor is less than a ratio of area of an illuminated portion of an active region of second thin film transistor to an area of the active region of second thin film transistor.
