Abstract
A display substrate is provided. The display substrate includes a plurality of functional material layers extending at least partially across multiple subpixels. The plurality of functional material layers include a first portion in an inter-subpixel region, and a second portion in subpixel regions. The first portion includes a doped impurity. The first portion and the second portion include at least one functional material in common. A weight percentage of the doped impurity in the first portion is higher than a weight percentage of the doped impurity in the second portion. The first portion spaces apart adjacent subpixels. The second portion includes a light emitting layer of a respective subpixel.
