Abstract
The present invention discloses a light-emitting device, array substrate, display device and manufacturing method of light-emitting device. The light-emitting device comprises a substrate and a pixel define layer provided on the substrate, the pixel define layer defines at least one pixel unit, each of which comprises a plurality of first electrodes, an organic layer provided on the plurality of first electrodes, and a second electrode provided on the organic layer. The light-emitting device, array substrate, display device and manufacturing method provided by the present invention can allow the formed film of the organic layer on the first electrodes to have good flatness and allow portions of the organic layer on different first electrodes to have substantially the same thickness, thus flatness and uniformity of the formed film of the organic layer in the light-emitting device is improved and further display quality of the light-emitting device is improved.
