1. A material with a hole injection function and/or a hole transport function, comprising:
a host material; and
a crystallisation inhibitor doped in the host material;
wherein the crystallisation inhibitor is capable of inhibiting crystallisation of the host material during evaporation, and has a hole injection function and/or a hole transport function; and
based on 100 parts by weight of the material with the hole injection function and/or the hole transport function, there are 90 to 99 parts by weight of the host material and 1 to 10 parts by weight of the crystallisation inhibitor.
