Abstract

A liquid crystal display panel and a manufacturing method thereof are provided. The liquid crystal display panel includes an active display region, a packaging region surrounding the active display region, and a fence structure arranged between the active display region and the packaging region, wherein, the fence structure includes multiple cylinders; there is a gap between every two adjacent cylinders, and a width of one side of the gap facing the packaging region is less than that of one side facing the active display region.

First claim

1 . A liquid crystal display panel, comprising an active display region, a packaging region surrounding the active display region, and a fence structure arranged between the active display region and the packaging region, wherein the fence structure includes multiple cylinders; there is a gap between every two adjacent cylinders, and a width of one side of the gap facing the packaging region is less than that of one side facing the active display region.

2 . The liquid crystal display panel according to claim 1 , wherein, in a planar view, along a direction from the packaging region to the active display region, the cylinders are gradually reduced in width.

3 . The liquid crystal display panel according to claim 2 , wherein, each of the cylinders is a trapezoidal cylinder or a triangular prism.

4 . The liquid crystal display panel according to claim 1 , wherein, an extension direction of each of the cylinders is a direction from the packaging region to the active display region.

5 . The liquid crystal display panel according to claim 1 , wherein, each of the cylinders includes a first cylinder part adjacent to the packaging region and a second cylinder part adjacent to the active display region, wherein the first cylinder part is connected with the second cylinder part, and a width of the first cylinder part is greater than that of the second cylinder part.

6 . The liquid crystal display panel according to claim 5 , wherein, in a planar view, the first cylinder part has a shape of trapezoid or square, and the second cylinder part has a shape of trapezoid, square or triangle.

7 . The liquid crystal display panel according to claim 6 , wherein, in the planar view, the first cylinder part has a shape of trapezoid, and the second cylinder part has a shape of square.

8 . The liquid crystal display panel according to claim 1 , wherein, the liquid crystal display panel comprises a color filter substrate; the fence structure is arranged on the color filter substrate, and the fence structure is shaped together with a planarization layer or a spacer in the color filter substrate.

9 . The liquid crystal display panel according to claim 1 , wherein, a dimension of the fence structure in a direction perpendicular to the liquid crystal display panel is less than or equal to a cell gap of the liquid crystal display panel.

10 . The liquid crystal display panel according to claim 9 , wherein, the dimension of the fence structure in the direction perpendicular to the liquid crystal display panel is less than the cell gap by 0.2 μm to 0.5 μm.

11 . The liquid crystal display panel according to claim 1 , wherein, a distance between the fence structure and the packaging region is 0 to 0.5 mm.

12 . The liquid crystal display panel according to claim 1 , wherein, the cylinders are evenly distributed in an annular region between the active display region and the packaging region.

13 . A manufacturing method for a liquid crystal display panel, comprising:
manufacturing a color filter substrate and an array substrate; filling a liquid crystal, and cell-assembling the color filter substrate and the array substrate to form the liquid crystal display panel; wherein, the liquid crystal display panel comprises an active display region and a packaging region surrounding the active display region, a fence structure is arranged between the active display region and the packaging region, the fence structure includes multiple cylinders; there is a gap between every two adjacent cylinders, and a width of one side of the gap facing the packaging region is less than that of one side facing the active display region.

14 .
