LIQUID CRYSTAL DISPLAY DEVICE
First Claim
1. A liquid crystal display device having a gradation display function of at least an n-number of gray levels and having a viewing angle characteristic of Mi/Mj≦
- 1.3 in a case where a display luminance range in a normal direction to a display surface in a gradation range of a gray level i to a gray level j is Li to Lj and a display luminance range in an oblique viewing-angle direction of 30°
or more is Mi to Mj (where n, i and j are real numbers, and n≧
i>
j≧
0), wherein the liquid crystal display device has a display mode in which a display image is displayed with a display luminance range of the display image being limited to Li to Lj.

Abstract
A liquid crystal display device has a gradation display function of at least an n-number of gray levels and has a viewing angle characteristic of Mi/Mj≦1.3 in a case where a display luminance range in a normal direction to a display surface in a gradation range of predetermined gray levels i to j is Li to Lj and a display luminance range in an oblique viewing-angle direction of 30° or more is Mi to Mj (where n, i and j are real numbers, and n≧i>j≧0). The liquid crystal display device has a display mode in which a display image is displayed with a display luminance range of the display image being limited to Li to Lj.
