  • Publication number: 20160054611
    Abstract: The present invention discloses a display substrate, a method of manufacturing the same, and a display apparatus. The display substrate comprises a substrate body and a support spacer provided on the substrate body. In the display substrate, a contact surface between the support spacer and the substrate body is configured to be a non-flat surface. On one hand, the non-flat contact surface has a larger contact area than a flat contact surface and increases an adhesion force between the support spacer and the substrate body. Thereby, it can prevent the support spacer from being separated from the substrate body. On the other hand, the non-flat contact surface can hinder the movement of the support spacer relative to the substrate body in some directions. Thereby, it also can prevent the support spacer from being separated from the substrate body.
