The present disclosure discloses a display panel and a display device. The display panel includes a cell defined by a first substrate and a second substrate oppositely arranged with respect to the first substrate, and a plurality of post spacers on the first substrate. The second substrate includes a plurality of sub-pixels, the post spacers include a first post spacer and a second post spacer at one side of the first post spacer away from the sub-pixels. A spacer supporting block protrudes from the second substrate, and enables an end portion of the first post spacer away from the first substrate not to contact with the second substrate when the display panel is subjected to an external force. The end portion of the first post spacer away from the first substrate and the spacer supporting block partially overlap with each other in a direction perpendicular to the second substrate.
