Display panel and display device
The invention discloses a display panel and a display device, the display panel is provided with a display area and a non-display area, and the display panel comprises a substrate; the dam is arranged in the non-display area of the substrate and surrounds the display area; the dam comprises a first dam, a second dam and a third dam, and the first dam, the second dam and the third dam are sequentially arranged in the direction away from the display area; wherein in the thickness direction of the base plate, the thickness of the second dam is smaller than that of the third dam; the organic packaging layer is located in the display area, extends to the non-display area and covers part of the dam; wherein the orthographic projection of the organic encapsulation layer on the substrate is at least partially overlapped with the orthographic projection of the second dam on the substrate. The ink overflows to part of the dams to form the organic packaging layer, so that concentrated stress borne by the packaging film layer at the first dam and the second dam can be reduced, and the risk of packaging failure caused by breakage of the packaging film layer is further reduced.
本申请公开了显示面板以及显示装置，显示面板具有显示区与非显示区，包括：基板；堤坝，设置在基板的非显示区，且环绕显示区；堤坝包括第一堤坝、第二堤坝以及第三堤坝，沿远离显示区的方向，第一堤坝、第二堤坝以及第三堤坝依次设置；其中，沿基板厚度方向，第二堤坝的厚度小于第三堤坝的厚度；有机封装层，位于显示区，且向非显示区延伸，并覆盖部分堤坝；其中，有机封装层在基板上的正投影，与第二堤坝在基板上的正投影至少部分交叠。本申请通过使墨水溢流至部分堤坝形成有机封装层，能够减小位于第一堤坝与第二堤坝处的封装膜层受到的集中应力，继而降低封装膜层断裂导致的封装失效的风险。
