An embodiment of the invention provides a conductive particle and a preparation method thereof, a conductive adhesive and a display apparatus and relates to the display technology field. Through using the preparation method, problems that processing is difficult and conductivity changes greatly existing in a carbon material applied in the conductive adhesive in the prior art can be solved. The preparation method comprises the following steps of forming sphere kernels; dispersing the sphere kernels in deionized water and adding organic polymer monomers so as to form a reaction solution; carrying out gamma ray irradiation on the reaction solution so that the organic polymer monomers generate a polymerization reaction on sphere kernel surfaces so as to form organic polymers; separating the sphere kernels whose surfaces form the organic polymers from the reaction solution so as to obtain the sphere kernels whose surfaces form the organic polymers; successively carrying out preoxidation and carbonization treatment on the sphere kernels whose surfaces form the organic polymers so that the organic polymers form a conducting layer formed by carbon particles so as to obtain the conductive particle formed by the conducting layer and the sphere kernels. The method is used for preparing the conductive particle and the conductive adhesive including the conductive particle and manufacturing the display apparatus.
