Abstract
An organic light emitting diode display panel is provided, including a first substrate, a second substrate opposite to the first substrate, at least one first light emitting layer on a side of the first substrate facing the second substrate, at least one second light emitting layer on the side of the first substrate facing the second substrate, the at least one second light emitting layer being separated from the at least one first light emitting layer, and at least two third light emitting layers on a side of the second substrate facing the first substrate. The at least one first light emitting layer and the at least one second light emitting layer are aligned with corresponding ones of the at least two third light emitting layers.
