Estimating the term…
A liquid crystal display apparatus includes a liquid crystal panel for data display comprising a pair of oppositely disposed substrates and a liquid crystal disposed between the substrates, a sheet of substantially transparent protection plate disposed opposite to and with a prescribed gap from a display surface of the liquid crystal panel for protecting the liquid crystal panel, and a polarizer sheet for selectively transmitting light having a plane of polarization in a prescribed direction disposed on at least the display surface of the liquid crystal panel. The display apparatus further includes an anti-reflection film disposed on at least a front surface on an opposite side with respect to the liquid crystal panel of the protection plate among two surfaces of the protection plate and a surface of the polarizer sheet. The anti-reflection film comprises a layer structure including at least one layer for promoting optical interference to decrease reflected light brightness and provided with surface unevennesses at a prescribed pitch.
An anti-reflection film, comprising transparent particles and a transparent binder, wherein the transparent particles are agglomerated at random as to provide a standard deviation .sigma. of agglomerate size distribution of at least 30% of average agglomerate size and bound with the transparent binder, to provide a surface unevenness exceeding an average particle diameter of the transparent particles and a porosity.
