    Abstract: A pixel definition layer and a manufacturing method thereof, a display substrate, and a display panel are provided. The pixel definition layer includes: a lyophilic material layer on a base substrate, which includes a plurality of lyophilic portions spaced in pairs, which being with an annular structure and used to define a pixel region; and a lyophobic material layer on a side of the lyophilic material layer from the base substrate, which being filled between each two adjacent lyophilic portions of the plurality of lyophilic portions, and a distance from a surface of the lyophobic material layer from the base substrate to the base substrate is larger than a distance from a surface of the lyophilic material layer from the base substrate to the base substrate. The pixel definition layer improves the uniformity of films formed in the pixel region by the solution.

    Abstract: Embodiments of the invention disclose a light emitting display panel. The light emitting display panel comprises a cover plate, a substrate disposed opposite to each other, a plurality of light emitting devices located between the cover plate and the substrate, and a packaging structure surrounding the light emitting devices. The packaging structure comprises at least three rows of protruded frames and a first packaging material which is located between adjacent protruded frames, wherein four sides of each of the protruded frames are looped and the at least three rows of protruded frames are adjacent to and embedded in each other in an outward direction. Adjacent ones of the at least three rows of protruded frames are alternately disposed on the cover plate and the substrate and protrude in opposite directions, and non-adjacent ones of the at least three rows of protruded frames are disposed on the same one of the cover plate and the substrate and protrude in the same direction. In the above light emitting display panel, resin adhesive or desiccant is filled in gaps between the frames so as to prolong an invasion path of water vapor and oxygen gas spatially, an effect of preventing water vapor and oxygen gas is thus increased. The light emitting display panel has advantages of good sealing property, simple manufacturing process and the like.

    Abstract translation: 本发明的实施例公开了一种发光显示面板。 发光显示面板包括盖板，彼此相对布置的基板，位于盖板和基板之间的多个发光器件以及围绕发光器件的封装结构。 包装结构包括至少三排突出框架和位于相邻突出框架之间的第一包装材料，其中每个突出框架的四个侧面环绕，并且至少三排突出框架邻近并嵌入 彼此在向外的方向。 所述至少三排突出框架中的相邻的突出框架交替地设置在所述盖板和所述基板上并且沿相反方向突出，并且所述至少三排突出框架中的不相邻的突出框架布置在所述盖板 板和基板并沿相同的方向突出。 在上述发光显示面板中，树脂粘合剂或干燥剂填充在框架之间的间隙中，以便在空间上延长水蒸气和氧气的侵入路径，从而提高了防止水蒸气和氧气的效果。 发光显示面板具有密封性好，制造工艺简单等优点。
