Abstract

Provided are a mask plate, a display substrate, a display panel and a display device. In the mask plate, an orthographic projection of at least one compensation light-shielding portion on a first base substrate is located between those of two adjacent light shielding portions. An orthographic projection of at least one compensation light-shielding portion in a second direction overlaps at least partially with that of a first width gradient portion of an ilight shielding portion in two adjacent light shielding portions, and an orthographic projection of the compensation light-shielding portion in a first direction overlaps at least partially with an orthographic projection of a first corner portion of a jlight shielding portion in the two adjacent light shielding portions. A corner of the first corner portion of the ilight shielding portion is oriented toward the jlight shielding portion.
