A drive circuit substrate, LED display panel and method of forming the same and display device are provided, in field of display technologies. The drive circuit substrate includes a base substrate and drive electrodes arranged in an array on a surface of the base substrate, where at least one conductive structure is arranged on a surface of each drive electrode away from the base substrate, the conductive structure is electrically connected to corresponding drive electrode. The driving electrodes include first and second driving electrodes, horizontal height of first driving electrode is greater than horizontal height of second driving electrode. The conductive structure includes first conductive structure on a surface of the first driving electrode away from the base substrate and second conductive structure on a surface of the second driving electrode away from the base substrate, height of second conductive structure is greater than height of first conductive structure.
