The invention provides a liquid crystal display panel and a display device employing the same. The liquid crystal display panel comprises a first substrate, a second substrate, a liquid crystal layer and quarter-wave pattern phase difference sheets. A second electrode of the second substrate comprises a first sub-pixel region and a second sub-pixel region. When pixels display an image, a voltage difference between a first voltage of the first sub-pixel region and a second voltage of the second sub-pixel region is in inverse proportion to a gray-scale value of the image displayed by the pixels. The liquid crystal display panel and the display device can improve the visual angles of the pixels.
