Liquid crystal display and display
View Patent ↗A liquid crystal display includes a liquid crystal display panel having a first substrate, a second substrate disposed on an observer side with respect to the first substrate and opposed to the first substrate, a liquid crystal held between the first substrate and the second substrate, an upper polarizing plate disposed on the observer side with respect to the second substrate, and a resin film disposed on the observer side with respect to the upper polarizing plate and affixed in contact with the upper polarizing plate. The resin film is higher in surface hardness than the upper polarizing plate and has a surface hardness of at least 3H in terms of surface pencil hardness. At least one of the first and second substrates has a thickness of no greater than 0.5 mm, and a total thickness of the liquid crystal display panel is no greater than 2 mm.
