Embodiment 1
[0052] Reference attached figure 1 -Attached Figure 7 , Embodiment 1 of the present invention proposes a preparation method of a display substrate, the preparation method comprising:
[0053] S1: forming a patterned film layer 2 on the base substrate 1, the first surface of the patterned film layer 2 having a pit portion 21 and a non-pit portion 22;
[0054] Specifically, refer to the appendix figure 1 , the material of the base substrate 1 is not specifically limited here, for example: it can be glass; the patterned film layer 2 can be any film layer on the base substrate 1, it can be a film layer, or it can be a plurality of film layers , for example: the patterned film layer 2 may include a plurality of film layers forming thin film transistors; the surface of the patterned film layer 2 is uneven, for example, the position of the thin film transistor will be slightly higher than other positions, so that the patterned film layer 2 formed is relatively The first surface o...
Embodiment 2
[0089] Reference attached Image 6 and attached Figure 7 , the second embodiment of the present invention provides a display substrate, the display substrate includes: a base substrate 1 and a patterned film layer 2 disposed on the base substrate 1, the first surface of the patterned film layer 2 is It has a pit part 21 and a non-pit part 22;
[0090] a planarization layer 3, the planarization layer 3 is disposed on the first surface of the patterned film layer 2;
[0091] The lyophilicity of the recessed portion 21 is higher than that of the non-recessed portion 22 , and the first surface is the surface of the patterned film layer 2 away from the base substrate 1 .
[0092] Specifically, the material of the base substrate 1 is not specifically limited here, for example: it can be glass; the patterned film layer 2 can be any film layer on the base substrate 1, it can be one film layer, or it can be a plurality of film layers. Membrane layer; the first surface of the patter...
Embodiment 3
[0103] The third embodiment of the present invention provides a display panel, the display panel includes: the above-mentioned display substrate.
[0104] Specifically, the display panel may be a liquid crystal display panel, or may also be an organic electroluminescence display substrate, which is not specifically limited here.
[0105] According to the above list, an embodiment of the present invention provides a display panel, including the above-mentioned display substrate, and the above-mentioned display substrate utilizes lyophilic and lyophobic properties, and considers the shrinkage ratio of the planarization layer 3 of the film layers with different thicknesses, The optimization of the flatness of the flattening layer 3 is realized, so that when other film layers are formed on the flattening layer 3, the uniformity of the other film layers is ensured, so that the light emitted from the display panel is uniform.
