A method for manufacturing a transflective LCD panel having a transmissive region and a reflective region includes steps of providing an upper substrate and a lower substrate in parallel, forming a first alignment film on the upper substrate, forming a reflective layer on the reflective region of the lower substrate, forming an first insulating layer to cover the reflective layer and the lower substrate, forming a second insulating layer to cover the first insulating layer, forming positive and negative driving electrodes wrapped in the second insulating layer, forming a coplanar second alignment film to cover the second insulating layer, packaging the upper substrate and the lower substrate, and filling liquid crystal molecules.
