Abstract

The invention discloses an organic electroluminescent display device, a manufacturing method of the display device and a display unit. The display device comprises a substrate, a hole injection layer, a hole transfer layer and an electron barrier layer, wherein the hole injection layer, the hole transfer layer and the electron barrier layer are sequentially arranged on the substrate, the hole transfer layer is made from P-type doped materials, the P-type doped LUMO energy level is close to the HOMO energy level of the body material of the hole transfer layer, and therefore electrons in the HOMO energy level of the body material of the hole transfer layer can jump to the P-type doped LUMO energy level so that the number of free hole carriers in the hole transfer layer can be increased, the mobility ratio of the hole carriers is increased so that the probability of the situation that the electrons and holes are compounded in a luminescent layer to form electron-hole pairs can be increased easily and the balance degree of the electron-hole pairs can be improved, and the luminous performance of organic light-emitting diodes (OLEDs) can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic electroluminescent display device, a manufacturing method and a display device. Background technique [0002] At present, organic electroluminescent display devices (Organic Electroluminescent Display, OLED) have gradually become the mainstream in the display field due to their excellent performances such as low power consumption, high color saturation, wide viewing angle, thin thickness, and flexibility. [0003] The basic structure of OLED, such as figure 1 As shown, it includes: anode 01, hole injection layer 02, hole transport layer 03, electron blocking layer 04, light emitting layer 05, hole blocking layer 06, electron transport layer 07, electron injection layer 08, cathode 09 arranged in sequence and cathodic protection layer 10. When no voltage is applied to the OLED, the energy levels of each material do not tilt, and the schematic diagram of the energy le...
