The combination of A Plate and C Plate can improve the visual angle of IPS-LCD. This paper studies the improvement in axis-off light leakage of in-plane-switching(IPS) liquid crystal display(LCD) using a laminated film of a
λ
/4 wave plate and a +C compensation film. According to theoretical investigation and experimental verification
this paper investigates the compensation phenomenon of laminated film in axis-off light leakage of IPS-LCD with different cell gap. An optimized combination of retardation value can be obtained. Especially
the
λ
/4+C plate with
R
th
=60 nm and
R
e
=140 nm can improve greatly the visual angle of IPS-LCD which is 4
