Cantor Colburn LLP
Optical film assembly and display device having the same
An optical film assembly includes a first polarization plate disposed below a liquid crystal layer and having a first absorption axis, a second polarization plate disposed above the liquid crystal layer and having a second absorption axis, an A-plate disposed between the first polarization plate and the second polarization plate, and a negative C-plate disposed between the first polarization plate and the second polarization plate. A thickness-direction phase retardation value of the negative C-plate is equal to or less than a value acquired by subtracting about 75 nanometers from a thickness-direction phase retardation value of the liquid crystal layer and the thickness-direction phase retardation value of the negative C-plate is equal to or greater than a value acquired by subtracting about 275 nanometers from the thickness-direction phase retardation value of the liquid crystal layer.
