The invention discloses an organic light emitting display panel and a
display device. The organic light emitting display panel comprises a substrate, an
organic light emitting device, a
package layer, a display region and a non-display region, wherein the non-display region is arranged at the periphery of the display region, the
organic light emitting device comprises a public negative
electrode layer, the public negative
electrode layer extends towards the non-display region from the display region, in a direction towards the non-display region from the display region, a sealing post is arranged at an end part of the public negative
electrode layer and covers a flat region of a pixel defining layer, and the
package layer covers the sealing post. The sealing post is arranged on the last flat region in contact with the public negative electrode layer and is used for limiting an edge of a negative electrode, a structure comprising the last flat region and the sealing post is used as a
bank of the
package layer, thus, the frame width of the organic light emitting display panel is further favorably reduced, and the organic light emitting display panel more conforms to the ultra-narrow frame requirement.
