Patent ID: 7820252

Claim:
A transflective film comprising a polymer film having an in-plane phase retardation value of about 30 nm or less and a single transflective layer consisting of at least one layer made of an inorganic compound, not of metal or polymer, wherein the transflective layer is coated on the polymer film in a continuous layer, the transflective layer has an utilization efficiency of light from about 80% to about 100%, a refractive index of the inorganic compound is about 1.9 or more and a reflectance of the transflective film is from about 10% to about 95%, and wherein when the transflective layer is a single layer structure, the optical thickness of the transflective layer is one-fourth of the specific wavelength in the visible region, and when the transflective layer is a multi layer structure, the optical thickness of at least one layer composing the transflective layer is one-fourth of the specific wavelength in the visible region.
