Title: ARRAY SUBSTRATE AND DISPLAY DEVICE
Abstract:
An array substrate and a display device. The array substrate comprises a base substrate (101), and a first conductive layer (106) and a second conductive layer (110) successively arranged on the base substrate, wherein at least two passivation layers (107, 108, 109), which are continuously arranged in a direction perpendicular to the base substrate, are arranged between the first conductive layer and the second conductive layer. The continuously formed passivation layers are configured in such a way that the better adhesiveness between the second conductive layer and the passivation layers in contact therewith can be achieved by means of adjusting the components of the passivation layers, so that the connection performance between various layers is more stable. The continuously formed passivation layers are configured in such a way that a groove (115) can be formed in the passivation layers so as to increase a height difference between non-electrical connection areas of an ACF adhesive (301), so that an anisotropic conductive adhesive in the groove is deformed or broken so as to increase the anisotropic conductivity of the ACF adhesive and reduce the short circuit and/or open circuit of a display screen. Accordingly, the stability, reliability and dependability of an array substrate can be improved.
