A transflective pixel structure in a liquid crystal display panel comprises lower and upper substrates opposing each other and a liquid crystal layer disposed therebetween. The lower substrate comprises a reflective region and an adjacent transmissive region. A protrusion is formed on the surface of the upper substrate facing and corresponding to the low substrate of the reflective region, wherein an edge of the protrusion defines a transition from the reflective region to the transmissive region, wherein such edge extends along a first direction. An alignment film covers the protrusion and the upper substrate, and is rubbed along a second direction parallel to the first direction or extending from the reflective region to the transmissive region to intersect with the first direction. A liquid crystal layer is disposed between the lower and upper substrates.
