Abstract: Provided are a display panel, a preparation method thereof, and a display apparatus. The display panel includes an array substrate and a color filter substrate aligned and combined into a cell. The color filter substrate includes a first base substrate and a plurality of color resist blocks arranged at intervals on the first base substrate. The array substrate includes a second base substrate and a plurality of pixel electrodes arranged at intervals on the second base substrate. The pixel electrodes are in one-to-one correspondence with the color resist blocks. The display panel includes a bending area and a non-bending area located at least on one side of the bending area. A density of the pixel electrodes in the bending area is less than that in the non-bending area, and a density of the color resist blocks in the bending area is less than that in the non-bending area.
