Abstract
An electro-wetting display device and a non-polar color solution thereof are provided. The electro-wetting device includes a first substrate, a second substrate, a polar solution layer and a non-polar color solution layer. The first substrate is opposite to the second substrate. The polar solution layer is disposed between the first substrate and the second substrate. The non-polar color solution layer is disposed between the first substrate and the polar solution layer and includes at least one non-polar solvent, at least one dye and at least one improvement agent. The improvement agent is dissolved in the non-polar solvent, and the improvement agent is not dissolved in the polar solution layer.
