Signal delay caused by load can be reduced, the transmission of common electrode signal is accelerated, improves display effect；And it leads due to first
Electric wire be it is identical as the extending direction of data line, the second conductor wire is, therefore first conductor wire identical as the extending direction of grid line
It is arranged in a crossed manner in display area with the second conductor wire, the first conductor wire and second being electrically connected with public electrode may be implemented
Conductor wire is evenly distributed, then corresponding first conductor wire in each region of public electrode and the second conductor wire are to be evenly distributed
, the homogeneity of common electrode signal can be improved, further increase display effect.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
