Retardation film for ips mode, polarizing plate comprising same, and liquid crystal display device comprising same

Provided is a retardation film for IPS mode, a polarizing plate comprising the same, and a liquid crystal display comprising the same. The retardation film for IPS mode has a thickness direction retardation (Rth) (450) of about -80 nm to about 0 nm at a wavelength of 450 nm, a thickness direction retardation (Rth) (550) of about -60 nm to about 10 nm at a wavelength of 550 nm, and an in-plane retardation (Re) of about 0 nm to about 10 nm at a wavelength of 550 nm. 本文揭示一种用于共面切换模式的相位差膜、一种包括其的偏光板以及一种包括其的液晶显示器。用于共面切换模式的相位差膜具有约-80纳米至约0纳米的在450纳米波长下的厚度方向相位差Rth(450)、约-60纳米至约10纳米的在550纳米波长下的厚度方向相位差Rth(550)以及约0纳米至约10纳米的在550纳米波长下的平面内相位差(Re)。
