Abstract:
1. A liquid crystal device comprising: a pair of substrates; a liquid crystal layer interposed between the pair of substrates; a planar region of the pair of substrates having at least one display pixel region, at least one viewing-angle control pixel region, a scanning line extending in a first direction, and a viewing-angle control line connected to the viewing-angle control pixel region and extending in a second direction crossing the first direction, the viewing-angle control pixel region performs dark display in the front direction of surfaces of the pair of substrates and has brightness variable depending on a viewing angle in an oblique direction to the normal direction of the surfaces of the pair of substrates; and a pair of electrodes driving the liquid crystal layer is provided in the display pixel region and the viewing-angle control pixel region on one substrate of the pair of substrates, wherein a first drive voltage applied between the pair of electrodes in the viewing-angle control pixel region at the time of driving the liquid crystal layer in the viewing-angle control pixel region is a voltage at which transmittance of the viewing-angle control pixel region in the oblique direction becomes maximum, the first drive voltage is higher than a second drive voltage applied between the pair of electrodes in the display pixel region, the second drive voltage being a voltage at which transmittance of the display pixel region in the normal direction becomes maximum, the first drive voltage is in a range of 10 to 15 V, and one electrode of the pair of electrodes in the viewing-angle control pixel region is directly connected to the viewing angle control line supplied with a control signal.
