  • Publication number: 20250127014
    Abstract: A display substrate and a display device are disclosed, relating to the technical field of displaying. The display substrate includes: a base substrate including a display region and a frame region surrounding the display region; a first dam portion, located at the frame region and surrounding the display region; and a second dam portion, located at the frame region. A maximum width of the second dam portion in a direction perpendicular to an extension direction of the second dam portion is less than a maximum width of the first dam portion in a direction perpendicular to an extension direction of the first dam portion, and the second dam portion is located at a side of the first dam portion adjacent to the display region. A narrow frame of the display substrate can be realized while ensuring the encapsulating performance.
