There is provided a polarizer integrally containing view angle compensating film used in an in-plane switching liquid crystal display (IPS-LCD) filled with liquid crystal (Δ∈>0) having positive dielectric anisotropy and an in-plane switching liquid crystal display comprising the same. More particularly, there is provided an integrated polarizer capable of being used to manufacture a thin polarizer and securing a good view angle by employing a view angle compensating film as a protective film of a polarizing film forming the polarizer and an IPS-LCD comprising the same. The integrated polarizer comprises a polarizing film; a protective film attached to one surface of the polarizing film; and a +A plate coated with a +C plate attached to the other surface of the polarizing film. The +C plate is coated in the form of liquid crystals.
