Abstract

The present application discloses an organic light-emitting device, a manufacturing method thereof, a display panel and a display device. The organic light-emitting device comprises a first electrode and a second electrode arranged on a substrate, and an organic light-emitting function layer positioned between the first and second electrodes. The second electrode comprises a plurality of second electrode blocks and second connection electrodes used for electrically connecting the second electrode blocks with one another. The organic light-emitting function layer comprises first organic material blocks configured to protrude towards the second connection electrodes. According to the technical scheme of the invention, organic material blocks configured to protrude towards the second connection electrodes are arranged on the organic light-emitting function layer, so that the contact area of the second electrodes with the organic light-emitting function layer is increased. The adhesive force between the second electrodes and the organic light-emitting function layer is improved, so that the generation of black spots is avoided.

Description

technical field [0001] The present application generally relates to the field of display technology, and in particular relates to an organic light emitting device, a manufacturing method thereof, a display panel and a display device. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode), as an active light-emitting display device, has the advantages of high brightness, fast response, bendability, ultra-thin and no backlight, and has important applications in the field of display technology, especially becoming the most Display devices that have the potential to replace liquid crystal displays. [0003] A prior art OLED device may comprise an anode 11, a hole transport layer 13, a light emitting layer 15, an electron transport layer 14 and a cathode 12, such as figure 1 shown. When a driving voltage is applied to the cathode 12 and the anode 11, the holes from the hole transport layer 13 and the electrons from the electron transport...
