Abstract
The invention relates to the field of display technique, particularly relates to an electrowetting display panel, a fabrication method thereof and a display apparatus comprising the same. The electrowetting display panel comprises a first substrate and a second substrate which are disposed opposite to each other, wherein the first substrate, the second substrate and the space therebetween are divided into a plurality of sub-pixel areas, and a baffle wall is disposed in the gap area between each two adjacent sub-pixel areas, characterized in that the baffle wall is formed from a material having both a hydrophilic group and a hydrophobic group. The electrowetting display panel has a simpler structure, the baffle wall thereof has a superior adhesiveness, and there is no necessary to form a hole in the hydrophobic dielectric layer to enhance the adhesiveness of the baffle wall during fabrication, such that the fabrication process is simplified.
