Abstract:
The present invention provides an optical film composite that comprises a linear reflective polarizing film; a birefringent polymeric substrate layer placed on the reflective polarizing film; and a TF (turning film) layer placed beneath the reflective polarizing film. The optical axis of the birefringent polymeric substrate layer is oriented with respect to the transmission axis of the reflective polarizing film to have 0° to 25° of an angular difference between the axes. The optical film composite can be employed in LCD devices to improve optical performance.
