Abstract

An electrowetting display, a pixel array substrate thereof, and an electrowetting display pixel structure thereof are provided. The electrowetting display pixel structure is disposed on a substrate. The electrowetting display pixel structure includes a pixel electrode, a hydrophobic insulating layer and a wall. The pixel electrode is covered by the hydrophobic insulating layer. The wall is disposed on the hydrophobic insulating layer. The wall has a first side surface, a second side surface and at least one opening penetrating the first side surface and the second side surface. The opening is used for fluid medium to flow therethrough.
