Abstract

Official abstract text for this publication.

An electrowetting display device includes a first substrate, a second substrate, a conductive fluid and a non-conductive fluid. The first substrate includes a first base substrate, a first electrode layer, a hydrophobic insulation layer and a partition wall. The first electrode layer is formed on the first base substrate and includes pixel electrodes spaced apart from each other and a common notch electrode formed between the pixel electrodes. The hydrophobic insulation layer is formed on the first electrode layer. The partition wall is formed surrounding the pixel electrodes and the common notch electrode on the hydrophobic insulation layer. The second substrate is opposite to the first substrate. The conductive fluid and the non-conductive fluid are interposed between the first and second substrates. The conductive fluid and the non-conductive fluid are controlled to vary transmittance of light in accordance with an electric signal applied to the pixel electrodes.
