Summary: | A display substrate, comprising: a base substrate (30), and a drive circuit layer, a first flat layer (35), and an organic packaging layer (42) which are sequentially arranged on the base substrate (30). The first flat layer (35) is provided with a first isolation groove (350) in a peripheral region (B1). The organic packaging layer (42) comprises a first part (421) and a second part (422) which are located in the peripheral region (B1). The second part (422) is located on the side of the first part (421) close to a display region (AA). The second part (422) has a first height. The height of the first part (421) gradually decreases from the first height to a second height in a direction away from the display region (AA). The first isolation groove (350) is located on the side of the first part (421) close to the display region (AA). The orthographic projection of at least one of the first part (421) and the second part (422) of the organic packaging layer (42) on the base substrate (30) covers the orthographic projection of the first isolation groove (350) on the base substrate (30). |
