LIQUID CRYSTAL DISPLAY AND METHOD FOR MANUFACTURING THE SAME |
摘要 |
A liquid crystal display is free from coloring of the display screen and has a high-contrast image quality, because (a) the direction of the twist angle of a twist phase plate (3) is opposite to that of the twist alignment of a liquid crystal element (2), and the twist angle of the twist phase plate (3) is 10 DEG to 40 DEG smaller than the twist angle of the liquid crystal element (2), (b) the direction of alignment of liquid crystal molecules of an alignment layer (23a) on the second substrate side and the direction of alignment of moleculus of the upper polymer (32b) in a liquid crystal polymer layer make an angle in the range of 80 DEG to 90 DEG , (c) the axis of absorption of a first polarizer (1) and the direction of alignment of liquid crystal molecules of the alignment layer (23b) on the first substrate side make an angle in the range of 50 DEG to 60 DEG , (d) the axis of absorption of the second polarizer (4) and the direction of alignment of molecules of the upper polymer (32a) in the liquid crystal polymer layer make an angle in the range of 30 DEG to 40 DEG , and (e) DELTA nd1 of a nematic liquid crystal layer and DELTA nd2 of the liquid crystal polymer layer are in a specific relationship.
