A brightness enhancement film coating material and an application thereof, where preparation raw materials for the coating material, in parts by weight, at least comprise the following components: 20-76 parts a monofunctional photocuring monomer, 20-76 parts a bifunctional photocuring monomer, 1-10 parts a photoinitiator, and 0-4 parts an auxiliary agent. No white streaks are produced after a brightness enhancement film formed by means of the present coating material undergoes a high-temperature high-humidity reliability test, and the adaptability of the brightness enhancement film and a polarizer is improved. Also, a reliability test is able to reflect, to a certain extent, a long-term use situation, and an excellent reliability test result can ensure long-term use stability of a display panel, and fragments produced during a cutting process are prevented from contaminating a film sheet and thereby affecting a use effect thereof.
