An electrophoretic display apparatus, adapted to be electrically connected with an external circuit, includes a driving array substrate, an electrophoretic display layer, and a first optical adhesive layer. The electrophoretic display layer includes a flexible substrate and a display medium layer. The flexible substrate has a configuration area and a bonding area. The external circuit is disposed between the flexible substrate and the driving array substrate. The external circuit is located in the bonding area and extends outside the driving array substrate. The display medium layer is disposed between the flexible substrate and the driving array substrate and located in the configuration area. The first optical adhesive layer is disposed between the display medium layer and the driving array substrate. A thickness of the external circuit is smaller than a sum of a thickness of the display medium layer and a thickness of the first optical adhesive layer.
