Abstract
(EN)
An organic light-emitting display panel, comprising: a first substrate, a second substrate, and a conductive spacer. The first substrate includes an auxiliary electrode arranged in a non-light-emitting area. The second substrate comprises: a thin film transistor substrate; a first electrode layer formed on the thin film transistor substrate; a pixel definition layer formed on the thin film transistor substrate and provided with a first recess in the non-light-emitting area, wherein there is a thickness difference between the first recess and the thin-film transistor substrate; an organic light-emitting layer overlying the first electrode layer and the pixel definition layer; and a second electrode layer formed on the organic light-emitting layer, wherein the second electrode layer traverses a plurality of light-emitting areas and the non-light-emitting areas, and there is a second recess corresponding to the first recess in the non-light-emitting area. The conductive spacer is located between the first substrate and the second substrate, arranged in the second recess 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 through the conductive spacer.
