Abstract:
A display apparatus includes a driving backplane and a light-emitting element. The driving backplane includes a substrate, a pixel driving circuit disposed on the substrate and a pad electrically connected to the pixel driving circuit. The pad has a first metal layer, a first intermetallic layer and a first diffusion barrier layer, wherein the first metal layer, the first intermetallic layer and the first diffusion barrier layer are sequentially stacked along a direction away from the substrate. The light-emitting element includes an electrode and a conductive bump electrically connected to the electrode. The conductive bump has a second intermetallic layer, and the first diffusion barrier layer is located between the second intermetallic layer and the first intermetallic layer.
