A transflective type blue phase liquid crystal display device and a liquid crystal display module of the same are disclosed. The transflective type blue phase liquid crystal display module includes an upper substrate, a lower substrate and blue phase liquid crystal molecules. Pixel electrodes and common electrodes are disposed alternately and disposed at intervals on an upper surface of each solid protrusion structure. Electric fields that are in parallel with a surface of each solid protrusion structure are generated in order to drive the blue phase liquid crystal molecules. Slope inclination angles provided at the upper portion and the lower portion of each solid protrusion structure are different such that optical delay properties at the transmissive region and the reflective region are identical.
