The present disclosure provides a bottom electrode substrate for a segment-type electrophoretic display. The bottom electrode substrate includes a flexible substrate, a first conductive layer, an insulating layer, a second conductive layer and a segment-type electrode. The first conductive layer is disposed on the flexible substrate. The insulating layer covers the first conductive layer and the flexible substrate, wherein the insulating layer has at least one opening exposing a part of the first conductive layer. The second conductive layer is filled in the opening and in contact with the exposed first conductive layer. The segment-type electrode covers the second conductive layer and the insulating layer, and is in contact with the second conductive layer. A method for manufacturing the bottom electrode substrate is also provided herein.
