Abstract
(EN)
The invention discloses a display panel, a manufacturing method thereof and a display device, and belongs to the technical field of display. The display panel comprises a display area, a base substrate, a display function layer, a hollow part, and at least one partition that is located between the display area and the hollow part, wherein an orthographic projection of the partition near the bottomsurface of the base substrate to the base substrate is a bottom surface pattern, a side of the bottom surface pattern near the hollow part is a first inner side, a side of the bottom surface patternaway from the hollow part is a first outer side, an orthographic projection of the partition to the base substrate is a partition pattern, a side of the partition pattern near the hollow part is a second inner side, a side of the partition pattern away from the hollow part is a second outer side, and the second inner side is located on the side of the first inner side near the hollow part. Different from prior art, when the display panel is cut to form the hollow part, the cutting process does not damage the inorganic film layer formed in the subsequent process of the partition. Therefore, cracks of the inorganic film layer are not caused, and the reliability of the display panel is improved.

本发明公开了一种显示面板及其制造方法、显示装置，属于显示技术领域，包括：显示区；衬底基板；显示功能层；镂空部；至少一个隔断部，隔断部位于显示区和镂空部之间；隔断部靠近衬底基板的底面向衬底基板的正投影底面图形，底面图形靠近镂空部的侧边为第一内侧边，底面图形远离镂空部的侧边为第一外侧边；隔断部向衬底基板的正投影为隔断部图形，隔断部图形靠近镂空部的侧边为第二内侧边，隔断部图形远离镂空部的侧边为第二外侧边；第二内侧边位于第一内侧边靠近镂空部的一侧。相对于现有技术，在切割显示面板形成镂空部时，切割工艺不会损坏隔断部后续工艺中形成的无机膜层，从而不会使无机膜层产生裂纹，提升显示面板的可靠性。
