Abstract
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.
