Abstract
A display device comprises a light emitting base layer, a transporting layer, a metal layer and a packaging layer that are sequentially stacked; the transporting layer comprising a conductive lead wire and a test pin; the metal layer comprising a plurality of metal blocks arranged in an array, each of the metal blocks being electrically connected to the test pin through the conductive lead wire; and the packaging layer being used for blocking outside moisture from contacting the metal layer, by testing the electric resistance of the metal block electrically connected to the test pin, determining the moisture blocking effect of the area of the packaging layer corresponding to the metal block. The moisture blocking effect of the area of packaging layer corresponding to the metal block can be determined, and the area where the moisture blocking effect of the packaging layer is poor can be accurately determined.
