Abstract
An organic light emitting diode display panel includes a pixel definition layer on a base substrate for defining a pixel having at least a first subpixel, a second subpixel, and a third subpixel; a first electrode in the first subpixel and the second subpixel; a first organic light emitting layer for emitting light of a first color in the first subpixel; a second organic light emitting layer for emitting light of a second color in the second subpixel; a second electrode on a side of the first organic light emitting layer and the second organic light emitting layer distal to the first electrode; a third organic light emitting layer for emitting light of a third color on a side of the second electrode distal to the base substrate; and a third electrode on a side of the third organic light emitting layer distal to the base substrate.
