Abstract
Disclosed are an array substrate, a display panel and a display device. The array substrate includes: a base substrate, electroluminescent devices located on the base substrates, and a reflection structure located on the side away from light exiting surfaces of the electroluminescent devices, where the reflection structure includes at least two groups of Bragg reflectors configured to reflect visible light in preset wave bands, the preset wave bands reflected by the different groups of Bragg reflectors are different, the various preset wave bands do not completely overlap, wavelength ranges of light emitted by the electroluminescent devices overlap with wavelength ranges of light reflected by the Bragg reflectors corresponding to the electroluminescent devices.
