A reflective display panel includes a first substrate and a second substrate. A thin film transistor and a reflective layer are disposed on the first substrate. A color resist layer is disposed on the second substrate. The reflective display panel includes a color sub-pixel region and a white sub-pixel region adjacent to each other. The color sub-pixel region has the color resist layer, and the white sub-pixel region has no color resist layer. A buffer layer is disposed in the white sub-pixel region on the first substrate or the second substrate. A cell gap between the first substrate and the second substrate in the white sub-pixel region is smaller than a cell gap between the first substrate and the second substrate in the color sub-pixel region. In this way, reflectivity and chromaticity can be improved.
