Abstract
A liquid crystal panel is provided which is capable of performing displaying with sufficiently high quality while reducing power consumption. The liquid crystal panel 20 includes a plurality of pixel electrodes, a plurality of counter electrodes which are smaller in number and larger in individual size than the plurality of pixel electrodes, a liquid crystal layer disposed between the plurality of pixel electrodes and the plurality of counter electrodes, and a control unit configured to control a voltage applied to the plurality of pixel electrodes and a voltage applied to the plurality of counter electrodes. In a predetermined case, the control unit operates in a power saving operation mode in which the control unit performs control such that a fixed voltage is applied to the plurality of pixel electrodes and a voltage corresponding to an image signal is applied to the plurality of counter electrodes.
