The first pixel comprises a first pixel electrode, a first switch and a second switch. The first input end of the first switch is coupled to the data line. The first controlled end of first switch is coupled to the first scanning line. The first output end of first switch is coupled to the first pixel electrode. The second input end of second switch is coupled to the data line. The second controlled line of second switch is coupled to the first scanning line. The second pixel comprises a second pixel electrode and a third switch. The third input end of third switch is coupled to the data line. The third controlled end of third switch is coupled to the second scanning line. The third output end of third switch is coupled to the second pixel electrode. The auxiliary electrode is coupled to the second output end of second switch and is adjacent to the second pixel electrode.

Description

technical field [0001] The present invention relates to a liquid crystal display panel and a liquid crystal display device using the same, and in particular to a liquid crystal display panel capable of reducing gray scale voltage offset and a liquid crystal display device using the same. Background technique [0002] Generally, liquid crystal displays with wide viewing angles mainly use protrusions (protrusion / bumps) on the electrodes of the upper and lower substrates, or design slits (slits) on the electrodes to pre-control the inversion of liquid crystal molecules. The above two methods for generating multi-domain effects have been widely used in liquid crystal displays. [0003] However, although the method of making bumps on the electrodes can achieve the effect of multiple display domains, since the finished bumps will have hypotenuses, boundary energy will be generated on the liquid crystals, so that the alignment direction of the liquid crystals is no longer perpendic...
