Abstract
A display panel and manufacturing method thereof, and electronic device are provided. The display panel comprises a flexible substrate, thin film transistor layer comprising a drain, anode layer, light-emitting layer, cathode layer and photoresist layer arranged sequentially in a stacked manner, wherein the anode layer and drain are electrically connected; the photoresist layer comprises a first photoresist layer, second photoresist layer and third photoresist layer arranged sequentially at intervals; all of the first, second and third photoresist layer are disposed on the surface of cathode layer; a first dielectric layer filling the space between the first and second photoresist layer, and a second dielectric layer filling the space between the second and third photoresist layer are included, and the first and second dielectric layer are used to absorb light incident from one side of photoresist layer away from cathode layer so as to improve contrast of the display panel.
