ABSTRACT:
A transflective liquid crystal display (LCD) panel includes a first substrate and a second substrate. The second substrate has a common electrode layer facing the first substrate. The first substrate has a plurality of pixel units. Each of the pixel units has a plurality of protrusions, a first reflective layer, a bumping layer, a second reflective layer, and a transparent conductive layer. Each of the protrusions has a through hole exposing a portion of the first substrate. The first reflective layer is disposed on the protrusions but not on the exposed portions of the first substrate. The bumping layer is disposed on the first reflective layer and the second reflective layer is disposed on the bumping layer. The transparent conductive layer covers the portions of the first substrate exposed by the through holes.
