Micro led display panel, method for fabricating the same and display device

A method for fabricating a Micro LED display panel, comprising:

• step S1, preparing an array substrate, wherein the array substrate comprises a transistor array layer, the transistor array layer comprises a plurality of pixel point regions, and each of the plurality of pixel regions is provided with at least one transistor;
• performing steps S2 to S4 at least once, comprising:
• step S2, forming an adhesive film layer on a surface of the array substrate on which the transistor array layer is provided, wherein the adhesive film layer comprises a retaining region and a removal region,
• step S3, embedding an LED chip array carried by a transfer substrate into the adhesive film layer, and separating the LED chip array from the transfer substrate, wherein the LED chip array comprises a plurality of LED chips, and
• step S4, exposing and developing the adhesive film layer, to remove the removal region of the adhesive film layer and LED chips in the removal region, wherein LED chips in the retaining region are in one-to-one correspondence with the pixel point regions of the transistor array layer;
• and
• step S5, forming an anode connecting electrode connecting an anode of each of the LED chips and a source or a drain of the transistor in one of the pixel point regions corresponding to the LED chip, and forming a cathode connecting electrode in contact with a cathode of the LED chip, to obtain a Micro LED display panel.
