Abstract
The present invention provides a liquid crystal display (LCD) panel and a display apparatus using the same. The LCD panel comprises a first substrate, a second substrate, a liquid crystal layer and quarter wave (λ/4) pattern retarder films. The second electrode of the second substrate comprises first sub-pixels and second sub-pixels. When images are displayed by the pixels, a voltage difference between a first voltage of the first sub-pixels and a second voltage of the second sub-pixels is inversely proportional to a grayscale of the images displayed by the pixels. The present invention can mitigate the viewing angle problem of the pixels.
