Abstract:
1. A display element that comprises a first substrate provided on a display surface side, a second substrate provided on a non-display surface side of the first substrate so that a predetermined display space is formed between the first substrate and the second substrate, an effective display region and a non-effective display region that are defined with respect to the display space, and a polar liquid sealed in the display space so as to be moved toward the effective display region or the non-effective display region, and that is capable of changing a display color on the display surface side by moving the polar liquid, wherein the display element comprises: a plurality of signal electrodes that are placed in the display space so as to come into contact with the polar liquid, and are also provided along a predetermined arrangement direction; a plurality of reference electrodes that are provided on one of the first substrate and the second substrate so as to be electrically insulated from the polar liquid and to be located on one of the effective display region side and the non-effective display region side, and are also arranged so as to intersect with the plurality of the signal electrodes; a plurality of scanning electrodes that are provided on one of the first substrate and the second substrate so as to be electrically insulated from the polar liquid and the plurality of the reference electrodes and to be located on the other of the effective display region side and the non-effective display region side, and are also arranged so as to intersect with the plurality of the signal electrodes; a plurality of pixel regions that are located at each of the intersections of the plurality of the signal electrodes and the plurality of the scanning electrodes; a rib that is provided on at least one of the first substrate and the second substrate so as to hermetically divide an inside of the display space in accordance with each of the plurality of the pixel regions; and an insulating fluid that is not mixed with the polar liquid and is movably sealed in the display space for each of the plurality of the pixel regions, wherein a movement space in which the insulating fluid is moved is provided in the display space for each of the plurality of the pixel regions, wherein the movement space is partitioned in the display space by using a plurality of protruding members that are provided on the other of the first substrate and the second substrate so as to protrude into the display space, and that are spaced at predetermined intervals; and wherein in the plurality of the protruding members, a distance between two adjacent protruding members and a distance between the rib and the protruding member that is adjacent to said rib are each set to be smaller than a size of the polar liquid in a direction perpendicular to the first substrate and the second substrate.
