Organic light-emitting diode device, organic light-emitting diode display apparatus, and preparation method for organic light-emitting diode device

摘要

There are provided an OLED device, an OLED display apparatus and a preparation method for an OLED device. The OLED device includes a pixel defining layer on a base substrate and an organic light-emitting functional layer in opening regions of the pixel defining layer, and further includes a first auxiliary electrode layer and a second auxiliary electrode layer which are arranged on the same layer The first auxiliary electrode layer and the second auxiliary electrode layer are arranged between the pixel defining layer and the base substrate, and an electric field can be formed between the first auxiliary electrode layer and the second auxiliary electrode layer. Organic light-emitting molecules in the organic light-emitting material are arranged directionally under the action of the electric field.
