Abstract

Disclosed is a display substrate, comprising a display area and a non-display area surrounding the display area. At least one limit mark group is disposed in the non-display area; the display area has a plurality of sides, and rounded chamfers are formed between adjacent two sides; the non-display area includes a frame part opposite to the sides of the display area and corner parts opposite to the rounded chamfers; and the limit mark group is located at the corner part. Accordingly, the disclosure also provides an organic light emitting device, a film vapor-deposition detecting method of an organic light emitting device, and a display device. According to the disclosure, it is possible to reduce the display defect and the accuracy of film vapor-deposition detection.
