Abstract: Optical compensation films and a method for reducing dark-state light leakage of vertical alignment liquid crystal displays are disclosed. The light path difference (LC?ND) is in a range of 324.3-342.8 nm, and the pretilt angle is in a range of 85 to 90 degrees when measured at a wavelength of 550 nm. Wherein an in-plain retardation value Ro of the biaxial compensation film is in the range of 48-84 nm, an out-of-plain retardation value Rth of the biaxial compensation film is in the range of 160-280 nm, and a retardation value Rth of the TAC compensation film is within a range between Y1 and Y2. The compensation structure with single layer of biaxial compensation film not only can reduce the dark-state light leakage, but also can increase the contrastness and the resolution in the wide viewing angle.

Abstract: An optical filter for reducing color shift in an LCD is disposed in front of an LCD panel of the LCD. The optical filter includes a color shift-reducing layer and an external light-blocking layer. The color shift-reducing layer includes a background layer and a plurality of engraved or embossed lens sections formed on the background layer such that the lens sections are spaced apart from each other. When light having different colors depending on the viewing angle and the grayscale level, owing to the birefringence characteristics of liquid crystal molecules, is emitted from the LCD panel, the lens sections diffuse the direction in which a portion of the light incident onto the lens sections is emitted, so that the portion of the light is mixed with another portion of the light passing between adjacent lens sections. The external light-blocking layer contains an anisotropic absorber.

A mechanical stress causing the stress-induced birefringence is produced in the such formed polarization-modulating optical element.
