Abstract

A display panel and a method for manufacturing a display panel are disclosed. The display panel includes a first sub-pixel region and a second sub-pixel region which are adjacent to each other. The display panel includes a substrate and a first conductive layer, an organic functional layer, and a second conductive layer which are sequentially on the substrate. The organic functional layer includes a charge generation layer, and the charge generation layer includes a first charge generation layer portion and a second charge generation layer portion which are in the first sub-pixel region and the second sub-pixel region, respectively. The display panel further includes a spacer between the first sub-pixel region and the second sub-pixel region, and the spacer disconnects the first charge generation layer portion and the second charge generation layer portion.
