Problems solved by technology

[0006] However, in the above-mentioned conventional field-of-view control type liquid crystal display device, one of the first electrode and the second electrode on the inner surface of one substrate of the above-mentioned liquid crystal display element and the third electrode on the inner surface of the other substrate are applied. A voltage between the above-mentioned first electrode and the second electrode that corresponds to the same value as the voltage of the image data or a value of 1 / n of the voltage corresponding to the above-mentioned image data bends the equipotential lines of the above-mentioned transverse electric field to make The liquid crystal molecules are aligned in an alignment state corresponding to the bending of the equipotential line, which narrows the display field of view, so the field of view fluctuates according to the above-mentioned image data, and stable field of view control cannot be performed.

Abstract

A plurality of common electrodes and signal electrodes insulating from each other are disposed on a substrate internal surface of liquid crystal displaying element for generating horizontal electric field, and contraposition electrodes corresponding to each whole region of multi pixel are set on internal surface of other substrate. The liquid crystal displaying element displays images by using driving unit to generate electric field between common electrodes and signal electrodes. The displayed image carries wide visual field display and narrow visual field display by selectively supplying visual field controlling signals to the contraposition electrodes, the changes of electric potential of the visual field controlling signals and the common signals supplied on the common electrodes change synchronously and respectively have scheduled potential difference corresponding to the electric potential of the common signals and the signal electrodes.
