Claims

[Scope of utility model registration request]

In a liquid crystal display device using a guest-host type liquid crystal with a homojunius orientation, the orientation direction of molecules is defined so that the direction in which the display is mainly viewed in the mounted state is approximately parallel to the long axis direction of the molecules of the liquid crystal. At the same time, on the front glass surface, the long axis of the molecules has a tilt angle that gradually moves away from the glass surface with respect to the 12:00 direction, and on the back glass surface, the long axis of the molecules has a tilt angle that gradually moves away from the glass surface with respect to the 6:00 direction. A liquid crystal display device having a tilt angle in the direction away from the camera.
