The backplane structure includes a lower substrate, a transistor formed on the lower substrate, and a lower electrode electrically connected to the transistor. The buffer layer is disposed on the backplane structure. The spacer wall is disposed on the buffer layer and forms a closed pattern. The display medium is disposed in the closed pattern. The display medium includes an electrophoretic medium and a plurality of electrophoretic particles dispersed in the electrophoretic medium. The upper substrate is disposed on the spacer wall and the display medium. The upper electrode is disposed between the upper substrate and the spacer wall.
