A display panel includes: a driving substrate, a plurality of first electrodes, a hole transport layer, an organic light emitting layer, a second electrode layer and a color film layer. The hole transport layer includes a first portion and a second portion, the first portion is disposed between adjacent ones of the plurality of first electrodes and is located on a surface of the driving substrate; the second portion is disposed on a surface of each of the first electrodes away from the driving substrate; a minimum distance between an upper surface of the first portion away from the driving substrate and the driving substrate is smaller than an minimum distance between an upper surface of the second portion away from the driving substrate and the driving substrate.
