Abstract
Techniques are provided to reduce color shifts in an LCD. A sub-pixel in the LCD may comprise a reflective part and a transmissive part. The reflective and transmissive parts may be covered by one or more retardation films. To reduce color shifts in general and especially in oblique viewing angles, at least one retardation film in the sub-pixel may comprise a slow axis with an elevation angle from a surface of a substrate layer of the LCD.
