Abstract
(EN)
An organic light emitting display panel, comprising a first substrate, a second substrate, and conductive spacers. The first substrate comprises an auxiliary electrode located in a non-light emitting region; the second substrate is provided opposite to the first substrate, and comprises a thin film transistor substrate, a first electrode layer formed on the thin film transistor substrate, an organic light emitting layer formed on the first electrode layer, and a second electrode layer formed on the organic light emitting layer; the second electrode layer crosses multiple light emitting regions and the non-light emitting region, and has a recessed portion in the non-light emitting region; the conductive spacers are located between the first substrate and the second substrate, and each conductive spacer is provided in the recessed portion and is in electrical contact with the auxiliary electrode and the second electrode layer, so that the auxiliary electrode is electrically connected to the second electrode layer by means of the conductive spacer.
