Liquid crystal display device

A liquid crystal display device having a liquid crystal lens arranged on a liquid crystal display panel,

• wherein the liquid crystal display panel includes pixels each having a red sub-pixel, a green sub-pixel, and a blue sub-pixel arranged in a first direction, which are provided in the first direction at first intervals, and further arranged in a second direction orthogonal to the first direction at second intervals;
• the liquid crystal lens is formed by interposing a liquid crystal between a first substrate and a second substrate;
• the first substrate includes a plurality of first electrodes in stripes, extending in the first direction, and arranged in the second direction each at an interval twice as large as the second interval, each of the plurality of first electrodes in stripes having a same width;
• the second substrate includes a plurality of second electrodes in stripes and a plurality of third electrodes in stripes, extending in the second direction, and arranged in the first direction at predetermined intervals, having the plurality of second electrodes arranged in the first direction at the interval twice as large as the first interval, each of the plurality of third electrodes in stripes having a width greater than a width of each of the plurality of second electrodes in stripes;
• an initial alignment of liquid crystal molecules between the first and second substrates is in the second direction;
• the plurality of second and the plurality of third electrodes are set to be at one potential, and a voltage is applied between the plurality of second electrodes and the plurality of first electrodes, and between the plurality of third electrodes and the plurality of first electrodes to allow a three-dimensional display;
• and
• the plurality of first electrodes and the plurality of third electrodes are set to be at the one potential, and the voltage is applied between the plurality of first electrodes and the plurality of second electrodes, and between the third and second electrodes to allow a three-dimensional display.
