HVA LIQUID CRYSTAL DISPLAY
First Claim
1. A HVA liquid crystal display panel, comprising an upper substrate, a lower substrate and a liquid crystal layer located between the upper substrate and the lower substrate;
- the upper substrate comprises a first substrate, and a common electrode layer located at one side of the first substrate facing the lower substrate;
the lower substrate comprises a second substrate, a plurality of gate scan lines and a plurality of data lines located on the second substrate;
the plurality of gate scan lines and the plurality of data lines crisscross to form a plurality of sub pixel areas;
the plurality of gate scan lines and the plurality of data lines are at borders of the plurality of sub pixel areas;
the common electrode layer comprises a hollow part correspondingly above the gate scan lines and the data lines, and no electric field generates among the hallow part and the gate scan lines, the data lines, to prevent border light leakage and color washout phenomenon of the sub pixel areas because liquid crystals in the area are driven for replacing a black matrix to achieve light shielding function.
