1. A curved liquid crystal display panel, comprising: a color film substrate and an array substrate that are arranged opposite to each other; wherein
a surface, distal from the array substrate, of the color film substrate is a display surface of the curved liquid crystal display panel, and the display surface is a concave display surface;
an orthographic projection of the color film substrate on the array substrate is within the array substrate;
the color film substrate comprises a first side surface and a second side surface that are arranged opposite to each other, wherein the first side surface and the second side surface are both arc-shaped side surfaces; and
the array substrate comprises a third side surface and a fourth side surface that are arranged opposite to each other, wherein the third side surface and the fourth side surface are both arc-shaped side surfaces; wherein
the first side surface is adjacent to and staggered from the third side surface, and the second side surface is adjacent to and staggered from the fourth side surface; and
at positions where the third side surface and the fourth side surface are disposed, each of a side, proximal to the color film substrate, of the array substrate and a side, distal from the color film substrate, of the array substrate comprises a structure formed by a grinding process;
the curved liquid crystal display panel has a display region and a non-display region disposed on a periphery of the display region;
wherein the curved liquid crystal display panel further comprises a side-coating adhesive disposed within the non-display region and arranged around the color film substrate and the array substrate;
wherein the array substrate comprises a plurality of bonding structures disposed within the non-display region, wherein an arrangement direction of the plurality of bonding structures is parallel to an extension direction of the third side surface, and the plurality of bonding structures are closer to the third side surface than to the fourth side surface;
wherein a vertical distance between the first side surface and the third side surface ranges from 2 mm to 2.5 mm; and
a vertical distance between the second side surface and the fourth side surface ranges from 0.3 mm to 1 mm.
