A polarizer construction is disclosed that includes a reflective polarizer
disposed on a first side of the construction to transmit light having one
polarization and reflect light having an orthogonal polarization, and one
or more colored dichroic polarizers disposed on a second side of the
construction. The one or more colored dichroic polarizers are arranged so
that when the construction is illuminated from the first side, an observer
viewing the construction from the second side will observe a first
spectral distribution of visible light, and when the construction is
illuminated from the second side, an observer viewing the construction
from the second side will observe a second spectral distribution of
visible light different from the first spectral distribution. Various
display constructions using colored polarizers to achieve color changing
and image reversal effects are also disclosed.
