<p>PROBLEM TO BE SOLVED: To obtain a liquid crystal display device in which the range of visual field angle is expanded by arranging the orientation direction of liquid crystal molecules on a first substrate so as to be parallel or so as to be orthogonal to the electric field direction. SOLUTION: The orientation direction of liquid crystal molecules 8 on a lower glass substrate is set to be roughly orthogonal and one side of axis of polarization 7 of a polarizing plate is arranged parallel and the other side of the axis of the polarization 7 is arranged orthogonal to a traverse electric field direction 9. Consequently, in an off state, the linearly polarized light made incident on a liquid crystal layer becomes to be in a state in which the plane of polarization of it is rotate by 90 degrees at the time of being emitted to become to be in a bright state transmitting an analyzer. Moreover, in an on state, since a traverse electric field is generated to deform the orientation so that the liquid crystal molecule 8 is parallel with the electric field, the linearly polarized light made incident on the liquid crystal layer is emitted in the same state of the linearly polarized state without being affected by an optical influence by a liquid crystal layer to be shaded by the analyzer. Thus, a dark state is realized. Moreover, the same effect is obtained even when the orientation direction of the liquid crystal molecule 8 on the lower glass substrate is set to be parallel with respect to the traverse electric field direction 9.</p> |
