Abstract

The invention discloses an organic electroluminescence display panel, a manufacturing method thereof and a display device. The organic electroluminescence display panel comprises a substrate, an anode, a cathode, an organic light-emitting layer and a semiconductor layer, wherein the anode and the cathode are located on the substrate, the organic light-emitting layer is located between the anode and the cathode, and the semiconductor layer covers the whole substrate; the semiconductor layer is located between the anode and the organic light-emitting layer or between the cathode and the organic light-emitting layer. The organic electroluminescence display panel has the advantages that a pixel definition layer in the prior art can be omitted, and pixel light-emitting areas can be increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic electroluminescent display panel, a manufacturing method thereof, and a display device. Background technique [0002] After nearly two decades of rapid development, organic electroluminescent devices (Organic Light Emitting Diode, OLED) have made a qualitative leap in material synthesis, device preparation and process integration. OLED has many advantages such as high efficiency, high brightness, high contrast, low power consumption, fast response, and flexible display. OLED will become the most powerful competitor of the next-generation mainstream flat-panel display technology. [0003] The pixel structure of the prior art OLED is as follows figure 1 Said, including several thin film transistor array circuits 11 located on the base substrate 10, the anode 12 located on the thin film transistor array circuit 11, the pixel definition layer 13 located on the anode 12, ...
