Problems solved by technology

[0004] In the actual production, the inventor found that the central area of ​​the end surface of the suspended end of the auxiliary spacer 02 prepared in the color film substrate currently has a concave part 021, which presents a concave basin shape. The auxiliary spacer in the color film substrate in the prior art Pad 02 has poor stability when supporting the array substrate, thereby reducing product performance

Embodiment 1

[0047] like Figure 2a and Figure 2b As shown, the display panel provided in this embodiment includes a first display substrate 31 and a second display substrate 32 disposed opposite to each other, and a main spacer 1 and an auxiliary spacer 1 disposed between the first display substrate 31 and the second display substrate 32 The spacer 2, the main spacer 1 and the auxiliary spacer 2 are all arranged on the first display substrate 31, or both the main spacer 1 and the auxiliary spacer 2 are arranged on the second display substrate 32, and at least The end face of the suspended end of an auxiliary spacer 2 is a plane, such as Figure 2a shown, and / or the end face of the suspended end of at least one auxiliary spacer 2 is convex, such as Figure 2b shown.

[0048]In the display panel provided by the present invention, the main spacer 1 and the auxiliary spacer 2 are arranged on the same display substrate, and the end face of the suspended end of at least one auxiliary spacer...

Embodiment 2

[0054] like image 3 As shown, the present embodiment provides a halftone mask for preparing a display panel, comprising a base substrate 4 and a light-shielding film layer 5 located on the base substrate 4, the light-shielding film layer 5 having an auxiliary spacer and an auxiliary spacer 2 One-to-one corresponding halftone light transmission area D, the halftone light transmission area D is as follows image 3 As shown by the dotted line box, the halftone light-transmitting area D is provided with a half-tone light-transmitting film 7, and the central area of ​​at least one half-tone light-transmitting film 7 is a hollow area.

[0055] When using the halftone mask provided by the present invention to prepare the auxiliary spacer in the display panel, the central area of ​​the halftone light-transmitting area D is a hollow area. The phenomenon of light interference in the area, so as to fully expose the center position of the end face of the suspended end of the auxiliary s...

Embodiment 3

[0058] like Figure 4 As shown, this embodiment provides a method for preparing a halftone mask, including:

[0059] Step S401 : forming a light-shielding film layer on a base substrate, and forming an opening area of ​​a halftone light-transmitting region on the light-shielding film layer through a patterning process;

[0060] Step S402 : forming a halftone light-transmitting film on the base substrate after the above steps have been completed, and forming a hollow region in the central region of the halftone light-transmitting region through a patterning process.

[0061] In a specific implementation manner, step S401 may specifically include:

[0062] A light-shielding film layer 5 is formed on the base substrate 4, and a layer of photoresist 6 is coated on the light-shielding film layer 5, such as Figure 5a shown;

[0063] Using a drawing and developing process, the photoresist is formed into a photoresist removal area and a photoresist retention area; the photoresist ...

Abstract

The invention discloses a display panel. The display panel comprises an oppositely-arranged first display substrate and a second display substrate, as well as a primary spacer and an auxiliary spacer, which are arranged between the first display substrate and the second display substrate, and is characterized in that the primary spacer and the auxiliary spacer are arranged on the first display substrate, or the primary spacer and the auxiliary spacer are arranged on the second display substrate, in addition, the end surface of one suspension end of the at least one auxiliary spacer is the plane surface, and / or the end surface of one suspension end of the at least one auxiliary spacer is the convex surface. In the display panel provided by the invention, the supporting stability of the auxiliary spacer is higher. The invention further provides a half-tone mask plate for preparing the display panel and the preparation method of the half-tone mask plate. The invention further provides the preparation method of the display panel and a display device adopting the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a preparation method thereof, a mask plate and a preparation method thereof, and a display device. Background technique [0002] In today's display technology industry, a display panel is formed by cell-aligning a first display substrate and a second display substrate. In order to maintain the cell thickness between the two, a spacer is usually set between the first display substrate and the second display substrate pads to achieve. [0003] Take the main spacer and the auxiliary spacer in the liquid crystal display panel (including the oppositely arranged color filter substrate and the array substrate) both arranged on the color filter substrate as an example, such as figure 1 As shown, the spacers on the transparent substrate 03 of the color filter substrate are divided into a main spacer 01 and an auxiliary spacer 02, wherein the main spacer 01 is...
