Abstract

A display panel is provided. The display panel includes a first substrate faces a second substrate. The first substrate includes a plurality of first spacers and a plurality of second spacers. The second substrate includes a corresponding plurality of first protrusions and a plurality of second protrusions. A sum of a height of the first protrusion and a height of the first spacer is greater than that of the second spacer. Each of the first spacers includes at least one protrusion. A length of an orthographic projection of each protrusion on a plane of the first substrate is longer in one direction.
