Abstract: A display device, including: a substrate; a first light-emitting element disposed on the substrate; an encapsulation layer disposed on the first light-emitting element; an input sensing layer disposed on the encapsulation layer; and a diffraction pattern layer disposed on the input sensing layer. The diffraction pattern layer may include a plurality of diffraction patterns arranged to have a first period in one direction.

Abstract: A display device includes a substrate, a first display element which is disposed on the substrate, and a plurality of diffraction patterns which are disposed on a path of light emitted from the first display element and arranged along a direction with a first period. when a width of a cross section of one of the plurality of diffraction patterns is defined as a first length, the first period and the first length satisfy Inequality (1):

0.4≤d1/DP1≤1,  (1)



where DP1 is the first period, and d1 is the first length.
