A liquid crystal display device including a liquid crystal panel being capable of gradation display is provided with a LUT and a drive signal generation section for adjusting gradation curve's distortion with respect to a viewing angle, which indicates a relation between a gradation and a luminance ratio on a display screen of the liquid crystal panel. With this arrangement, it is possible to freely switch on the display screen of the liquid crystal panel between a wide viewing angle display and a narrow viewing angle display. Therefore, it is possible to provide a liquid crystal display device which adjusts the gradation curve's distortion with respect to the viewing angle on the display screen to obtain a high contrast and an excellent gradation curve in a wide range of viewing angle, thereby improving a display quality level of a display screen; and which realizes a display screen with a narrow viewing angle, thereby allowing information not desired to be seen by other people to be securely displayed thereon. |
