Abstract

The embodiment of the invention discloses an organic light-emitting diode display panel and a production method thereof. The organic light-emitting diode display panel comprises a first substrate and a second substrate which are oppositely arranged, wherein the first substrate comprises a first lead wire connected with a negative electrode; the second substrate comprises a second lead wire connected with a peripheral circuit; the first lead wire is connected with the second lead wire through a connecting part. According to the technical scheme adopted by the invention, the negative electrode is connected with the peripheral circuit through the first lead wire, the connecting part and the second lead wire, the first lead wire is arranged on the first substrate and the second lead wire is arranged on the second substrate, so that the first lead wire and the second lead wire are difficult to break, poor contact, caused by easy breakage of the lead wires, between the negative electrode and the peripheral circuit in the prior art is avoided, good contact between the negative electrode and the peripheral circuit is ensured, and thus good display of the OLED (organic light-emitting diode) display panel is achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light emitting diode display panel and a manufacturing method thereof.
