Abstract
Embodiments of the present disclosure disclose a display panel and a fabricating method thereof. In the solution, on one hand, water-absorbing magnetic nanoparticles in a packaging layer are distributed along a direction perpendicular to the cover plate at a side far away from an OLED component, or distributed along an extension direction of the packaging layer at a periphery of a region in which the OLED component is located, thus reducing the damage to the OLED component of a display substrate. On the other hand, since the water-absorbing magnetic nanoparticles have magnetic property, the water-absorbing magnetic nanoparticles can be doped in the packaging layer material in a packaging and waterproofing process, and a magnetic field is applied to induce the magnetic nanoparticles to move to the side far away from the OLED component or to the periphery of the region in which the OLED component is located.
