Transflective liquid crystal display panel having a plurality of apertures with a specific ratio of aperture width to aperture interval
The present invention discloses a transflective liquid crystal display panel, which includes a first substrate, a second substrate and a liquid crystal layer sandwiched between the first and second substrates, so as to constitute a plurality of pixels each divided into a transmission region and a reflective region. Within the reflective region, a first common electrode layer formed on the first substrate corresponds to both of a second common electrode layer and a pixel electrode layer formed on the second substrate, wherein the pixel electrode layer is exposed from a plurality of apertures formed on the second common electrode layer. This varies distribution of the electric lines so as to control tilts of the liquid crystals in the reflective region. By the tilts, a total retardation change value achieved in the reflective region can gradually reach consistent with a total retardation change value achieved in the transmission region. It means that transmittances of both regions can reach consistence with each other under the same driving voltage.
