Abstract

Provided are a display device and a preparation method thereof. The display device includes a display panel and a first antireflection structure and a second antireflection structure successively stacked on a side of a display functional layer facing away from a driving substrate, where the display panel includes the driving substrate and the display functional layer. The first antireflection structure includes a first graded-index layer, a conductive layer and a second graded-index layer which are successively stacked; the first graded-index layer includes at least two first sublayers, and the second graded-index layer includes at least two second sublayers. The second antireflection structure includes a third graded-index layer, a first dielectric layer and a fourth graded-index graded layer which are successively stacked; the third graded-index layer includes at least one third sublayer, and the fourth graded-index layer includes at least two fourth sublayers.
