摘要： Provided is a curved liquid crystal display panel, including a color film substrate and an array substrate. An orthographic projection of the color film substrate on the array substrate is within the array substrate. The color film substrate includes a first side surface and a second side surface. The array substrate includes a third side surface and a fourth side surface. The first side surface is adjacent to and staggered from the third side surface. The second side surface is adjacent to and staggered from the fourth side surface. 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 includes a structure formed by a grinding process.
