## Abstract

Embodiments of the present disclosure provide a display substrate, including: a base substrate; a light emitting device on the base substrate; an encapsulating layer on the base substrate and configured to encapsulate the light emitting device; and an anti-vibration layer on the base substrate. An orthographic projection of the anti-vibration layer on the base substrate has no overlap with an orthographic projection of the light emitting device on the base substrate. The orthographic projection of the anti-vibration layer on the base substrate has an overlap with an orthographic projection of the encapsulating layer on the base substrate, and the overlap is smaller than the orthographic projection of the anti-vibration layer on the base substrate in area. The embodiments of the present disclosure further provide a manufacturing method of a display substrate, a display module, and a display device.
