Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; may be mechanically connected, may be electrically connected or may be in communication with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.
An embodiment of the present invention provides a spacer manufacturing apparatus, as shown in fig. 1, including a first heating member 1, an exposure member 2, a developing member 3, a photo-curing member 4, and a second heating member 5. The first heating member 1 is used for carrying out first heating treatment on the color filter substrate 100 coated with the spacer material 200 so as to carry out first curing on the spacer material 200; the exposure member 2 is used for performing exposure treatment on the spacer material 200 after the first curing; the developing member 3 is used for performing a developing process on the spacer material 200 after the exposure process; the light-curing member 4 is used for carrying out a second curing process on the spacer material 200 subjected to the exposure and development process; the second heating member 5 is used to perform a second heating process on the spacer material 200 after the second curing to obtain a spacer. As shown in fig. 2, the spacer of the present invention can be similar to a cylindrical structure, and includes a first bottom surface S1, a second bottom surface S2 and a side surface S3, the first bottom surface is located on the color filter substrate 100, the area of the first bottom surface is greater than or equal to the area of the second bottom surface, and as shown in fig. 3, the included angle θ between the side surface S3 and the first bottom surface S1 is 60 ° to 90 °.
The spacer material 200 may be a photoresist. After the spacer material 200 is exposed and developed, the surface of the spacer material 200 is in strong contact with a light source to generate strong cross-linking reaction, so that an inverted trapezoidal columnar structure is formed. After the photo-curing process, the cross-linking reaction on the surface and the bottom of the spacer material 200 is further enhanced, and the phenomenon of solvent flow inside the spacer material 200 is inhibited. After the post-baking process, a large amount of solvent components in the spacer material 200 volatilize, the surface of the spacer material 200 collapses downwards to form a regular trapezoidal columnar structure, so that the shape of the spacer is as close to a cylinder as possible, and a finer spacer is formed.
In the prior art, as shown in fig. 4, an included angle θ between the side surface S3 of the spacer and the first bottom surface S1 is generally 40 ° to 60 °, so that the area difference between the first bottom surface S1 and the second bottom surface S2 is large, and the first bottom surface S1 needs to occupy a large area of the color filter substrate 100. In the invention, the shape of the spacer is approximate to a cylinder, the area difference between the first bottom surface S1 and the second bottom surface S2 is smaller, the area of the first bottom surface S1 is smaller than that of the first bottom surface S1 of the spacer in the prior art, and under the same density of the spacer, the area of the color filter substrate 100 occupied by the spacer is smaller, thereby reducing the aperture ratio loss of the display panel.
In one embodiment, the first heating member 1 may be a heating plate, and the color filter substrate 100 is placed on the heating plate, and the heating plate starts to generate heat, so that the spacer material 200 on the color filter substrate 100 is heated to start the first curing.
In one embodiment, a mask is disposed over the spacer material 200, and the exposure member 2 emits UV (ultraviolet) light, which is irradiated on the spacer material 200 through the mask.

The light-curing member 4 irradiates the spacer material 200 with UV (ultraviolet) light, and the spacer material 200 is cured. The position where the light curing member 4 is disposed may be selected according to the production environment.
