Abstract
A display device having a surface treating film formed on the outer surface of a substrate of the display device, said surface treating film having a property of changing light transmittance or refractive index by light or UV rays, and/or containing a compound which can be deposited by irradiation with light, shows excellent antireflective antistatic properties and low surface resistance, and can be applied to flat cathode-ray tubes.
