A liquid crystal cell comprising: a first substrate and a second substrate provided oppositely, wherein the first substrate and the second substrate are both of a rectangular shape, and the first substrate and the second substrate are both of transparent substrates; a liquid crystal layer formed between the first substrate and the second substrate; and first spacers patterned and arranged at a preset interval on the side of the first substrate close to the liquid crystal layer, and second spacers patterned and arranged at a preset interval on the side of the second substrate close to the liquid crystal layer; wherein each of the first spacers and the second spacers has a cross section taken in a direction parallel with the first substrate and the second substrate, and a length of the cross section in a length direction is greater than a width of the cross section in a width direction, and on the respective said side of the first substrate or second substrate an angle between the length direction of the cross section of the spacer and an X-direction of its respective substrate is greater than 0° and less than 90°, or greater than 90° and less than 180°, and wherein the X-direction is parallel to a long side of the respective substrate; all of the first spacers and the second spacers have the same shape, and, on the respective said side of the first substrate or second substrate, when viewed from the liquid crystal layer side, the same length direction; the first spacers on the first substrate and the second spacers on the second substrate are arranged oppositely and abut with each other to keep a distance between the first substrate and the second substrate. a first substrate and a second substrate provided oppositely, wherein the first substrate and the second substrate are both of a rectangular shape, and the first substrate and the second substrate are both of transparent substrates; a liquid crystal layer formed between the first substrate and the second substrate; and first spacers patterned and arranged at a preset interval on the side of the first substrate close to the liquid crystal layer, and second spacers patterned and arranged at a preset interval on the side of the second substrate close to the liquid crystal layer; wherein each of the first spacers and the second spacers has a cross section taken in a direction parallel with the first substrate and the second substrate, and a length of the cross section in a length direction is greater than a width of the cross section in a width direction, and on the respective said side of the first substrate or second substrate an angle between the length direction of the cross section of the spacer and an X-direction of its respective substrate is greater than 0° and less than 90°, or greater than 90° and less than 180°, and wherein the X-direction is parallel to a long side of the respective substrate; all of the first spacers and the second spacers have the same shape, and, on the respective said side of the first substrate or second substrate, when viewed from the liquid crystal layer side, the same length direction; the first spacers on the first substrate and the second spacers on the second substrate are arranged oppositely and abut with each other to keep a distance between the first substrate and the second substrate.
