Color blocking crossover position.The color blocking crossover position is the overlapping region of adjacent color blocking.
In embodiments of the present invention, in Y direction, set on the first metal layer 102 of the corresponding passage 111
Public electrode wire 112, to realize shading.That is, in the data wire direction, the common electrical for corresponding to the passage 111 is widened
The width of polar curve, to realize shading.Preferably, the width of the public electrode wire of the corresponding passage is more than or equal to described
The width of passage.
In embodiments of the present invention, in X-direction, set in the second metal layer 106 of the corresponding passage 111
Metal wire 113, to realize shading；In the present embodiment, the metal wire 113 is the prolongation of electric leakage polar curve.I.e. described
Scan-line direction, by extending electric leakage polar curve to the position of the passage so that the part of extension can shelter from passage,
To realize shading.The width of the metal wire 113 is more than or equal to the width of the passage.
In embodiments of the present invention, color blocking crossover position can be that red color resistance and blue color blocking overlap, red color resistance and
Green color blocking overlaps, and either, blue color blocking and green color blocking overlap.So that red color resistance and blue color blocking are overlapping as an example, excavate
The color blocking of passage can be blue color blocking, red color resistance can also be dug out passage.
In summary, in order to not increase cost, the present invention is not on the basis of planarization layer is increased, to the knot of color blocking stacking
Structure is changed, to increase PI and liquid crystal circulation.Passage is excavated in the overlapping place of the color blocking of chromatic filter layer, now
Due to there was only one layer of color blocking at passage, so can not play a part of shading, the risk for having light leak, now the present invention is in Y-axis
Direction, sets public electrode wire on the first metal layer of the corresponding passage, and in X-direction, described in correspondence
Metal wire is set in the second metal layer of passage, to cover light leak herein.The embodiment of the present invention can not only effectively hide
Light leak is covered, and the circulation of PI and liquid crystal can also be increased.
Although the present invention, those skilled in the art have shown and described relative to one or more implementations
Based on the reading to the specification and drawings and understand it will be appreciated that equivalent variations and modification.The present invention includes all such repair
Change and modification, and be limited only by the scope of the following claims.In particular, to the various functions performed by said modules, use
