Provided is a display panel including a first substrate, a second substrate placed opposite to the first substrate, and at least one detector placed between the first substrate and the second substrate; each of the at least one detector includes a photosensitive portion located at a side of the first substrate facing the second substrate, and an accommodation portion located between the photosensitive portion and the second substrate, the accommodation portion includes an accommodation space and an opening facing the photosensitive portion; when distance between the first and second substrates changes, an proportion of the photosensitive portion accommodated in the accommodation portion changes so that light received by the photosensitive portion changes; when the photosensitive portion senses change of the light received, a resistance value of the photosensitive portion changes, and then the photosensitive portion outputs a different sensing signal. Further provided is a display device containing the display panel.
