Abstract
A display device including a display screen having an optical film provided thereon. The optical film is a porous thin film made of fine magnesium fluoride particles and a binder containing a condensate of a silane compound having a fluoroalkyl group, a co-condensate of the silane compound and silicon, or a co-condensate of the silane compound and a metal oxide compound. The combination of the specific binder and fine magnesium fluoride particles permits forming a porous optical film having a surprisingly high mechanical strength, excellent resistance to humidity and reduced external light reflection from the display plane.
