DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Following combines the drawings and embodiments to describe the present disclosure in detail.

Refer to FIG. 1, FIG. 1 is a structure schematic diagram of a liquid crystal display panel of the present disclosure. In the present embodiment, the liquid crystal display panel includes a first substrate 11, a second substrate 12 and a liquid crystal layer 13 between the first substrate 11 and a second substrate 12, on the first substrate 11 is disposed a first supporting pole 14, the first supporting pole 14 stretches towards the second substrate 12 and is disposed with a gap of said second substrate 12, a position of a surface of the second substrate 12 towards the first supporting pole 11 and faces the supporting pole 14 is disposed a roughened region, the roughened region comprises at least one notch.

Preferably, in the present embodiment, the liquid crystal display panel is curved surface liquid crystal display panel, the figure is only schematic, in actually, the first substrate 11 and the second substrate is bendable.

Combine FIG. 1 and further refer to FIG. 2, FIG. 2 is a top view schematic diagram of a second substrate in FIG. 1. Preferably, in the present embodiment, at least one notch includes a first notch 121 and a second notch 122 which are circular, a diameter of the first notch 121 is less than the second notch 122 and is concentrically disposed with the second notch 122.

Preferably, the second substrate 12 is a thin film transistor array substrate 12, the first substrate 11 is a color filter substrate 11.

Preferably, the surface of the second substrate 12 towards the first substrate 11 is disposed a flattening layer (unmarked), the notch is disposed on the flattening layer, for example, the corresponding position of the flattening layer is etched to form the notch. For example, the liquid crystal display panel is FFS, Fringe Field Switching, panel, the outermost layer that the thin film transistor array substrate 12 adjacent to the first substrate 11 is PLN flattening layer. Carry on the grooving process on the position where the PLN flattening layer of the thin film transistor array substrate 12 faces the first supporting pole 14, the surface of the area that the first supporting pole 14 corresponds to the thin film transistor array substrate 12 becomes uneven through grooving, when the panel is twisted (including that curved surface liquid crystal display panel manufacturing process needs to be twisted or an unexpected twist during transport), the difficulty of displacement of the first supporting pole 14 increases, the displacement distance significantly reduces, this design can reduce the distance from the area A opposite the first supporting pole 14 to the pixel opening area B, such as reducing from 5 um to 10 um, thereby achieving the purpose of increasing aperture ratio, the effect of increasing the area of pixel opening area B is more significant on high PPI products, at the same time, the ability that the panel resists the external force also cloud improve, the alignment film will not be scratched by twisting nor does the light leakage generate, even if the distortion occurs, it will not affect the display quality, more significantly increasing the production yields.
