Description
Technical Field
The invention belongs to the field of display panels, and particularly relates to a display panel and a manufacturing method thereof.
Technical Field
In the prior art, a cassette process is a process of attaching an array (TFT) substrate and a Color Filter (CF) substrate. A spacer (PS) is used between the two substrates to support the cell thickness forming space, and in order to achieve fast response, a low cell thickness liquid crystal panel needs to be realized, and it is a common practice to realize the low cell thickness of the liquid crystal display panel by reducing the column height of the spacer.
However, when the spacer film layer is coated, if the spacer material film layer is too thin, the risk of film rupture is high, and the height uniformity of the spacer with low column height is poor, resulting in poor uniformity of panel box thickness.

Preferably, the height of the initial spacer is H1, the height of the spacer is reduced to H, and the thickness of the planarization layer is H2, where H is H1-H2.
Preferably, the flat layer is made of a material with poor fluidity or a material with good fluidity.

Drawings
The present invention will be further described in the following detailed description of preferred embodiments, which is to be read in connection with the accompanying drawings.
FIG. 1 is a schematic diagram illustrating a manufacturing method of a display panel according to the present invention.
Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will be made with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
For the sake of simplicity, the drawings only schematically show the parts relevant to the present invention, and they do not represent the actual structure as a product. In addition, in order to make the drawings concise and understandable, components having the same structure or function in some of the drawings are only schematically illustrated or only labeled. In this document, "one" means not only "only one" but also a case of "more than one".
The technical solution of the present invention is described in detail with specific examples below.
The invention provides a manufacturing method of a display panel, as shown in fig. 1, comprising the following steps:
s1: forming an initial color film substrate 100;
s2: a plurality of initial spacers 041 with a height H1 are formed on the side of the initial color film substrate 100 opposite to the array substrate 200.
The initial color film substrate 100 is a substrate before a spacer and a planarization layer are not formed, and includes a base substrate 01, black matrixes 02 located on the base substrate 01, and a color resistance layer 03 located between adjacent black matrixes 02. The color resistance layer 03 may be RGB or RGBW, and is adjusted according to the actual panel.
S3: a planarization layer 05 with a thickness of H2 is coated on the basis of step S2.
Wherein the planarization layer 05 covers the initial spacer 041, the black matrix 02 and the color-resist layer 03.
S4: the planarization layer 05 covering the initial spacer 041 is removed and a spacer 04 is formed on the basis of step S3.
The initial spacer 041 is manufactured first, then the planarization layer 05 is coated, and then the planarization layer 05 on the upper layer of the initial spacer 041 is removed, so that the column height of the initial spacer 041 is reduced through phase change, and the height of the finally formed spacer 04 can be reduced to H (H-H1-H2), that is, the distance between the color film substrate 101 and the inner surface of the array substrate 200 in the display panel is correspondingly reduced.
The initial spacer 041 may be a spacer including only one height, or may be a spacer including two heights, namely a Main spacer (Main PS) and a Sub spacer (Sub PS), and the initial spacer 041 is set according to the requirement of the display panel. When the initial spacer 041 only includes spacers of one height, the distance between the color film substrate 101 and the inner surface of the array substrate 200 in the display panel is H (H-H1-H2); when the initial spacer 041 includes spacers with two heights, i.e., a Main spacer (Main PS) and a Sub spacer (Sub PS), the distance between the color film substrate 101 and the inner surface of the array substrate 200 in the display panel is the height of the Main spacer — the thickness H2 of the planarization layer.
The distance between the inner surfaces of the color film substrate 101 and the array substrate 200 in the display panel is H.
In the actual process, the thickness H2 of the planarization layer 05 can be adjusted according to the requirement of the panel box thickness, so as to obtain display panels with different box thicknesses.
Compared with the previous process steps, the invention does not directly thin the material film layer of the spacer, but only adjusts the process sequence of the flat layer 05 and the initial spacer 041 and the thickness of the flat layer 05, so as to realize the purpose of reducing the height of the spacer 04 and achieving the low box thickness of the display panel.
S5: the color filter substrate 101 and the array substrate 200 formed in step S4 are aligned and bonded to form a panel.
The flat layer 05 formed as described above may be made of a material having poor fluidity, or may be made of a material having good fluidity. When the planarization layer 05 is made of a material with poor fluidity, the step S4 of removing the planarization layer 05 covering the initial spacer 041 may be performed by etching; when the flat layer 05 is made of a material having good fluidity, the method of removing the flat layer 05 covering the initial spacer 041 described in step S3 is to remove the flat layer 05 by utilizing the fluidity of the flat layer 05 itself.
Wherein, step S1 includes the following steps:
s11: a black matrix 02 arranged in a matrix is formed on the base substrate 01;
s12: a color resist layer 03 is formed between the adjacent black matrices 02.
This forms the original color film substrate 100.
The invention also discloses a display panel which is manufactured by the manufacturing method of the display panel.
The invention adopts the method of firstly manufacturing the initial spacer, then coating the flat layer and then removing the flat layer on the upper layer of the initial spacer, and combines with the adjustment of the thickness of the flat layer, thereby reducing the height of the initial spacer, realizing the target of low box thickness of the display panel and improving the response speed of the panel.
It should be noted that the above mentioned embodiments are only preferred embodiments of the present invention, but the present invention is not limited to the details of the above embodiments, and it should be noted that, for those skilled in the art, it is possible to make various modifications and amendments within the technical concept of the present invention without departing from the principle of the present invention, and various modifications, amendments and equivalents of the technical solution of the present invention should be regarded as the protection scope of the present invention.
