  • Publication number: 20230035525
    Abstract: Disclosed are an array substrate, a display panel, a display device, and a manufacturing method of the array substrate. The array substrate includes a substrate layer, a passivation layer and a filter layer sequentially stacked. A side of the passivation layer facing the filter layer is provided with a concave-convex structure. By setting the concave-convex structure, when the light rays hit the uneven structure, the passivation layer region of the concave-convex structure can function as a lens. According to the principle of light scattering, light is scattered or diffused in the concave-convex structure to increase the propagation paths of light, more light can pass through the passivation layer and the light transmittance is improved. According to the principle of light diffraction, a new light source is formed at the position of the concave-convex structure to increase the light density and the light transmittance is improved.
