Abstract: The present disclosure provides a 3D display substrate including: a plurality of sub-pixels of different colors, a driver and a plurality of plano-convex lenses located at a light-emitting side of the plurality of sub-pixels. The plurality of sub-pixels are corresponding to the plurality of plano-convex lenses in a one-to-one manner. A light-emitting surface of each of the plurality of sub-pixels is located in a focal plane of the corresponding plano-convex lens. Each of the plurality of sub-pixels includes a plurality of sub-pixel sub-portions arranged in an array. The driver is configured to drive the plurality of sub-pixel sub-portions in the same sub-pixel to display images of different grayscales to form a 3D display image.

Abstract: Disclosed are a display substrate and a method for manufacturing the same, a display panel and a display device. The display panel includes a carrier substrate; an adhesive layer, a color resist layer, a first flat layer and a metal wire grid layer that are distributed in a direction distal from the carrier substrate; and a light shielding pattern disposed between the adhesive layer and the first flat layer. A surface of the light shielding pattern proximal to the metal wire grid layer is in the same plane as a surface of the color resist layer proximal to the metal wire grid layer. The present disclosure contributes to increasing the yield of the metal wire grid layer and improving the display effect of the display panel.
