  • Patent number: 8537455
    Abstract: A display device includes a first substrate, a second substrate, a plurality of display units and a plurality of partitioning walls. The second substrate is disposed above the first substrate. The display units are disposed between the first substrate and the second substrate, and each of the display units has a dielectric solvent. The partitioning walls are disposed between adjacent display units correspondingly, and a dielectric constant of each of the partitioning walls is less than that of the dielectric solvent adjacent thereto. Because the dielectric constant of the partition walls is less than that of the dielectric solvent adjacent to the partition wall, a capacitance value induced at the partition wall by a driving voltage can be decreased. Thus, crosstalk phenomena can be avoided in the display unit that is not driven.
