Abstract
A substrate includes a first base, a pixel defining layer and spacers. The pixel defining layer disposes above the first base and has a plurality of openings. The pixel defining layer includes a first pixel defining sub-layer and a second pixel defining sub-layer stacked in a direction away from the first base. The spacers dispose on a surface of the pixel defining layer facing away from the first base. The second pixel defining sub-layer includes a first conductive material doped at least in a surface of the second pixel defining sub-layer facing away from the first base, the spacers include a second conductive material doped at least in surfaces of the spacers facing away from the first base.
