The invention discloses a method for improving glare of a display. The method comprises the following steps: S1, preparing a reflection barrier layer for absorbing regular reflection of light on the display; and S2, preparing a transparent protective layer on the reflection barrier layer. According to the display glare improvement method, the blocking structure for absorbing regular reflection of the light is prepared on the display, regular reflection, refraction, scattering, total reflection and the like of the light are destroyed, transmission of the light in the transverse direction and the longitudinal direction is blocked, and the glare problem is solved.
