1. A display panel, comprising:
an array substrate comprising a blind hole area and a display area, wherein the blind hole area has an inner diameter area and an outer diameter area surrounding the inner diameter area;
a liquid crystal layer disposed on the array substrate and comprising spacers, wherein the spacers comprise a plurality of first column spacers and a plurality of second column spacers, and the first column spacers have a height greater than that of the second column spacers; and
a color filter substrate disposed on a side of the liquid crystal layer away from the array substrate;
wherein the first column spacers are disposed in the display area and excluded from the blind hole area, one end of each of the first column spacers is connected to the array substrate, another end of each of the first column spacers is connected to the color filter substrate, the second column spacers are disposed in the display area and the outer diameter area, and the second column spacers are apart from the array substrate; and
wherein in the display area, the spacers disposed in an area adjacent to the outer diameter area are the second column spacers.
