Electrowetting display apparatus and method of manufacturing the same

摘要

A manufacturing method of an electrowetting display apparatus, in which a pixel electrode is formed on a substrate including pixel areas, a first mixture including a hydrophobic material and a solvent is disposed on the substrate to form a hydrophobic insulating layer, and a first heat process is performed to remove a portion of the solvent. Then, a second mixture including a material for a barrier and the solvent is disposed on the hydrophobic insulating layer, and the second mixture is patterned to form a barrier wall surrounding the pixel electrode in each pixel area. A second heat process is performed to remove the solvent in the hydrophobic insulating layer and the barrier wall, and a polar fluid and a non-polar fluid are disposed on the pixel electrode to form an electrowetting layer.
