ABSTRACT:
An exemplary electro-wetting display (EWD) device includes a plurality of sub-pixel units. Each sub-pixel unit defines two opposite long sides and two opposite short sides. Each sub-pixel unit includes a first substrate, a second substrate facing toward the first substrate, a conductive first liquid and a polar second sandwiched between the first substrate and the second substrate, and an electrode. The first and second liquids are immiscible. The electrode is disposed at a surface of the second substrate facing the first liquid. The electrode defines an opening. A length of the opening as measured parallel to the nearest short side is not less than 0.8 times a length of the nearest short side.
