Abstract
A display panel, a method for testing a cell gap thereof, and a display device are disclosed. The display panel includes a first substrate and a second substrate arranged opposite to each other, wherein a light shielding layer is provided on a side of the first substrate close to the second substrate, a portion of the light shielding layer located in a peripheral region includes a plurality of opening areas arranged at intervals, each opening area being provided with a light transmissive layer; and wherein the second substrate has a light transmissive area, an orthographic projection of the light transmissive layer on the second substrate at least partly overlaps with the light transmissive area on the second substrate.
