Transflective film, transflective polarizer, and polarizing light source device and liquid crystal display device using the same |
摘要 |
The present invention provides a transflective film comprising a polymer film having an in-plane phase retardation value of about 30 nm or less and a transflective layer made of an inorganic compound, wherein the transflective layer is coated on the polymer film and a reflectance of the transflective film is from about 10% to about 95%. When an absorption-type polarizer is laminated to the polymer film side of the transflective film, a transflective polarizer is provided. When a reflection-type polarizer is laminated to the transflective layer side of the transflective film, a transflective polarizer used in a system improving luminance is provided. Using these transflective polarizers, a polarizing light source device and a transflective liquid crystal display device are provided.
