Abstract:
1. An in-plane switching liquid crystal display (IPS-LCD) comprising a first polarizing plate, a second polarizing plate, an horizontally oriented IPS panel disposed between the first and second polarizing plates and filled with a liquid crystal having positive dielectric constant anisotropy (Δε>0), and a first protective film disposed between the first polarizing plate and the IPS panel, in which an absorption axis of the first polarizing plate and an absorption axis of the second polarizing plate are orthogonal to each other, and an optical axis of the liquid crystal in the IPS panel and the absorption axis of the first polarizing plate are parallel with each other, wherein a phase retardation film, obtained by coating a biaxial film with a uniaxial C film, is disposed between the second polarizing plate and the IPS panel and is used as a second protective film between the IPS panel and the second polarizing plate.
