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) retarder films. The liquid crystal layer is formed between the first substrate and the second substrate. The second substrate comprises a second electrode, wherein the second electrode comprises a trunk portion and plurality of branch portions, and there are a first angle and a second angle between the trunk portion and the branch portions. The first angle is of 45 degrees, and the second angle is less than or greater than 45 degrees. The λ/4 retarder films are bonded to outer surfaces of the first substrate and the second substrate. The present invention can improve the color shift problem and the transmittance of the LCD panel. |
