发明名称 LIQUID CRYSTAL DISPLAY DEVICE
摘要 <p>The present invention provides a circularly polarizing VA mode liquid crystal display device having an excellent gray scale viewing angle from an intermediate gray scale to a high gray scale at an azimuth angle of 45°. The liquid crystal display device according to the present invention includes: a first polarizer; a first »/4 plate; liquid crystal cell; a second »/4 plate; and a second polarizer in this order, wherein when an azimuth of an absorption axis of the second polarizer is defined as 0°, an in-plane slow axis of the second »/4 plate forms an angle of approximately 45°; an in-plane slow axis of the first »/4 plate forms an angle of approximately 135°; the absorption axis of the first polarizer forms an angle of approximately 90°, and wherein a display brightness is varied by changing an alignment state of liquid crystal molecules in a liquid crystal layer from a state that the liquid crystal molecules are approximately vertically aligned to a substrate surface, to a state that the liquid crystal molecules are tilted to the substrate surface; and the liquid crystal layer has a domain in which the liquid crystal molecules are tilted in an azimuth angle range of 12.5° to 32.5°, a domain in which the liquid crystal molecules are tilted in an azimuth angle range of 102. 5° to 122.5°, and a domain in which the liquid crystal molecules are tilted in an azimuth angle range of 192.5° to 212.5°, and a domain in which the liquid crystal molecules are tilted in an azimuth angle range of 282.5° to 302.5°.</p>
