Display panel, preparation method thereof and display device

Abstract

The invention discloses a display panel, a preparation method thereof and a display device, relates to the technical field of display, and aims at solving the problem that since an insulating spacer moves to an opening area, display property of a display panel is decreased. The display panel comprises an opening area, a non-opening area arranged around the opening area, and the insulating spacer inside the non-opening area; the non-opening area is further provided with a liner structure which is positioned near the insulating spacer and used for preventing the insulating spacer from moving to the opening area. By arranging the liner structure inside the non-opening area and near the insulating spacer, the location of the insulating spacer is limited to prevent the insulating spacer from moving into the opening area, so that the distribution changes of liquid crystal around the insulating spacer due to the changes of the location of the insulating spacer are avoided, and meanwhile, it is also avoided that since the insulating spacer moves to the opening area, the insulating spacer shields light penetrating through the opening area. Therefore, it can be prevented that since the insulating spacer moves the opening area, the distribution of the liquid crystal and the aperture opening ratio of the display panel are affected, and the display property of the display panel is further improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Existing display panels generally include two display substrates facing each other, liquid crystal filled between the two display substrates, and a spacer arranged in a non-opening area of ​​one of the display substrates to maintain the thickness of the cell. For example, the display panel includes an array substrate and a color filter substrate, and spacers are arranged on the array substrate, such as figure 1 As shown, the array substrate includes a plurality of pixel areas defined by intersections of a plurality of gate lines 11 and a plurality of data lines 13, and each pixel area includes an opening area 1 (that is, the opening area 1 of the display panel) and surrounding opening areas 1 In the non-opening area 2 (that is, the non-opening area 2 of the display panel...

AI Technical Summary

Problems solved by technology

[0003] Based on the above structure, although the spacers 20 provided in the non-opening area 2 of the array substrate can support the box body to maintain a certain box thickness, there are still the following disadvantages: when the array substrate and the color filter substrate are combined to form a display panel , if a certain external force is applied to the display panel, the spacer 20 may move into the opening area 1 under the action of the external force, which will not only affect the arrangement of liquid crystals around the spacer 20, but also block the opening area. 1 The transmitted light causes a decrease in the aperture ratio, thereby affecting the display performance of the display panel
