    摘要： A composite film including a first polarizing film, at least one second polarizing film, and at least one first phase compensation film is provided. The first polarizing film has a first transmission axis. Each second polarizing film has a second transmission axis parallel to the first transmission axis. The at least one first phase compensation film is disposed between the first polarizing film and the at least one second polarizing film. Each first phase compensation film has a first optical axis. An orthographic projection of the first optical axis on the first polarizing film is parallel to an axial direction of the first transmission axis, and a first included angle between the first optical axis and the first polarizing film is greater than 0 degrees and less than 90 degrees. A display device is also provided.

    摘要： An optical system comprising: an optical component operable to be associated with a reflective LC panel, the optical component comprising one or more birefringent films having, individually or collectively, an in-plane retardance that is substantially greater than the associated LC panel's in-plane OFF-state retardance; the optical component further being positioned in the optical system such that the optical component optimally compensates for the relative retardances between the optical component and the LC panel; and the optical component further being configured to compensate for out-of-plane retardance of the LC panel's OFF-state.

    摘要： The present invention provides an LCD device that has a higher contrast ratio in a wide viewing angle and that can be easily produced at low cost. The present invention is a liquid crystal display device, including in the following order:
    a first polarizer;
    a first birefringent layer;
    a first quarter-wave plate;
    a liquid crystal cell;
    a second quarter-wave plate;
    a second birefringent layer; and
    a second polarizer having an absorption axis orthogonal to an absorption axis of the first polarizer,
    wherein the first birefringent layer satisfies Nz > 0.9 and has an in-plane slow axis orthogonal to the absorption axis of the first polarizer;
    the first quarter-wave plate has an in-plane slow axis forming an angle of about 45° with the absorption axis of the first polarizer;
    the liquid crystal cell displays a black screen by aligning liquid crystal molecules in the liquid crystal cell vertically to a substrate surface;
    the second quarter-wave plate has an in-plane slow axis orthogonal to the in-plane slow axis of the first quarter-wave plate; and
    the second birefringent layer satisfies Nz
