The present disclosure provides a conductive particle and a preparation method thereof, a conductive adhesive and a display device. The preparation method comprises steps of: forming cores; dispersing the spherical cores in deionized water and adding organic polymeric monomers so as to form a reaction solution; radiating the reaction solution with γ rays so that the organic polymeric monomers are polymerized on surfaces of the cores so as to form organic polymers; separating the spherical cores formed with the organic polymers on their surfaces from the reaction solution so as to obtain them; successively carrying out preoxidation and carbonization treatment on the cores formed with the organic polymers on their surfaces so that the organic polymers form a conductive layer consisting of carbon particles so as to obtain conductive particles each consisting of the conductive layer and the core.
