Abstract:
1. A liquid crystal display panel comprising: a first substrate comprising a first electrode; a second substrate comprising a second electrode, first pixel regions, second pixel regions and third pixel regions, wherein the second electrode has a pixel electrode structure, and the pixel electrode structure comprises a trunk portion and plurality of branch portions, and there is a first predetermined angle between the trunk portion and the branch portions in each of the first pixel regions, and there is a second predetermined angle between the trunk portion and the branch portions in each of the second pixel regions, and there is a third predetermined angle between the trunk portion and the branch portions in each of the third pixel regions, and the first predetermined angle and the second predetermined angle are less than or greater than 45 degrees, and the first predetermined angle, the second predetermined angle and the third predetermined angle are different from each other; a liquid crystal layer formed between the first substrate and the second substrate; a first polarizer disposed at an outer side of the first substrate; a second polarizer disposed at an outer side of the second substrate; and a half wave pattern retarder film bonded to an outer surface of the first substrate or the second substrate, wherein the half wave pattern retarder film comprises a plurality of first half wave retarder rows, a plurality of second half wave retarder rows and a plurality of third half wave retarder rows, and the first half wave retarder rows are positioned to the first pixel regions, and the second half wave retarder rows are positioned to the second pixel regions, and the third half wave retarder rows are positioned to the third half wave retarder rows; wherein the half wave pattern retarder film is positioned between the first substrate and the first polarizer; wherein, when the first predetermined angle, the second predetermined angle and the third predetermined angle are less than 45 degrees, and there is an angle (ψ) between a slow axis of the half wave pattern retarder film and an absorption axis of the first polarizer, and the first predetermined angle, the second predetermined angle or the third predetermined angle (θ) and the angle (ψ) satisfy the following equation: Wherein, when the first predetermined angle, the second predetermined angle and the third predetermined angle are greater than 45 degrees, and there is an angle (ψ) between a slow axis of the half wave pattern retarder film and an absorption axis of the first polarizer, and the first predetermined angle, the second predetermined angle or the third predetermined angle θ and the angle (ψ) satisfy the following equation:
