Abstract
The present disclosure provides a pixel define structure, a display panel and a method for manufacturing the same, and a display device, relating to the technical field of display. The pixel define structure includes a pixel define layer including a lyophobic material on a substrate, wherein the pixel define layer includes a stacked multilayer including at least a first layer and a second layer, the first layer being located between the substrate and the second layer, wherein a mass percent of the lyophobic material in the second layer is greater than a mass percent of the lyophobic material in the first layer.
Claims20
A pixel define structure, comprising:
- a pixel define layer on a substrate, wherein the pixel define layer comprises a stacked multilayer comprising at least a first layer and a second layer, the first layer being located between the substrate and the second layer,
- wherein:
- a number of layers of the stacked multilayer is greater than two;
- each layer of the stacked multilayer comprises a lyophobic material;
- and
- a mass percent of the lyophobic material in each layer of the stacked multilayer increases gradually in a direction from the substrate to the pixel define layer.
A method for manufacturing a display panel, comprising:
- providing a substrate;
- forming a patterned mask layer on the substrate;
- forming a pixel define layer on a region of the substrate where the patterned mask layer is not formed, wherein the pixel define layer comprises a stacked multilayer comprising at least a first layer and a second layer, the first layer being located between the substrate and the second layer, wherein a number of layers of the stacked multilayer is greater than two, each layer of the stacked multilayer comprises a lyophobic material, and a mass percent of the lyophobic material in each layer of the stacked multilayer increases gradually in a direction from the substrate to the pixel define layer;
- and
- removing the patterned mask layer.
The method according to 11, further comprising:
- forming, before forming the patterned mask layer, an electrode on the substrate, wherein the patterned mask layer covers at least a part of an upper surface of the electrode.
A method for manufacturing a display panel, comprising:
- providing a substrate;
- forming a patterned mask layer on the substrate;
- forming a pixel define layer comprising a lyophobic material, by an ink jet printing process, on a region of the substrate where the patterned mask layer is not formed, wherein the pixel define layer comprises a stacked multilayer comprising at least a first layer and a second layer, the first layer being located between the substrate and the second layer, wherein a mass percent of the lyophobic material in the second layer is greater than a mass percent of the lyophobic material in the first layer;
- and
- removing the patterned mask layer,
- wherein forming the pixel define layer by the ink jet printing process comprises:
- printing a first solution containing the lyophobic material on the region of the substrate to form the first layer;
- and
- printing a second solution containing the lyophobic material on the first layer to form the second layer, wherein the mass percent of the lyophobic material in the second solution is greater than the mass percent of the lyophobic material in the first solution.
