In an electrophoretic display apparatus, a first substrate includes a plurality of pixels each including at least two sub-pixels which display colors different from each other, and a second substrate which faces the first substrate and includes a reference electrode corresponding to a boundary between adjacent sub-pixels in each pixel. An electrophoretic material is between the first substrate and the second substrate. A barrier wall is between the first substrate and the second substrate, and defines the pixels.

Electrophoretic display aparatus and method of driving the same

An electrophoretic display apparatus includes a first substrate including a plurality of pixels, a second substrate facing the first substrate, an electrophoretic material between the first and second substrates, and a first electrode on the first substrate or the second substrate. Each pixel includes a reflection part and a second electrode. The reflection part is on the first substrate and reflects light incident through the second substrate. The second electrode is on the first substrate and adjacent to the reflection part. The second electrode forms an electric field with the first electrode such that the electrophoretic material moves to the first electrode or the second electrode. An upper surface of the second electrode is positioned at a first height from the first substrate, and an upper surface of an uppermost layer of the reflection part is positioned at a second height higher than the first height.
