Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As described in the background art, in available liquid crystal display panel, the transmitance of each sub-pixel of pixel unit is identical,
But since the color blocking layer light transmittance of different colours is different, it will lead to each sub-pixel emergent ray in pixel unit and pass through color blocking
Brightness is inconsistent after layer, so that quality white light of the pixel unit when white light is shown is poor.
To solve the above-mentioned problems, a kind of embodiment is to raise sub-pixel, the pixel of sub-pixel for double in the prior art
Electrode includes multiple polyline shaped electrodes, and polyline shaped electrode has two sections of strip electrodes, has between two neighboring polyline shaped electrode
It cracks.Shading strip is set in color membrane substrates corresponding two strip shaped electric poles junctions, the screening of different subpixel in same pixel unit
Striation is of different size, to adjust the transmitance of different subpixel.
Another embodiment is the pixel electrode of different colours sub-pixel in the same pixel unit of setting in the prior art
Cracking with different number.The pixel electrode has multiple strip shaped electric poles, since the pixel electrode of sub-pixel has difference
Quantity is cracked, in different colors sub-pixel have different quantity strip shaped electric poles.
First way is to need to increase shading strip in black matrix" by adjusting black matrix" in color membrane substrates, with
The transmitance of sub-pixel is adjusted, the second way is by adjusting the quantity of cracking in the pixel electrode of sub-pixel, so that different
Quantity of cracking in the pixel electrode of sub-pixel is different, changes the structure of pixel electrode, largely to adjust sub-pixel
Transmitance.The two ways is required to largely change the structure of display panel, leads to complex manufacturing technology, cost of manufacture
Increase, and the light transmittance of display panel largely changes, and can make the degradation in contrast of display panel.

It sets in the sub-pixel, the public electrode and/or the public electrode are provided with and crack, cracking in the same sub-pixel
It is parallel to each other, passes through the transmitance of the adjustable sub-pixel that cracks.By being arranged in the same pixel unit, until
Cracking in few two sub-pixels is not parallel, the transmitance of the sub-pixel can be made not exactly the same, so that described
The brightness of sub-pixel emergent ray is inconsistent, the brightness it is inconsistent with color blocking layer caused by the sub-pixel emergent ray brightness
It is inconsistent to offset, to eliminate or completely eliminate to a certain extent the problem of quality white light difference.Technical solution of the present invention
The electronic equipment use the liquid crystal display panel, therefore white light display when, have preferable quality white light, white balance compared with
It is good.
The liquid crystal display panel can will be cracked and be opened in pixel electrode setting based on the display pattern of liquid crystal display panel
Seam or public electrode setting crack or pixel electrode and public electrode simultaneously be arranged crack, do not change the layer for setting of cracking
Secondary structure.
Such as the liquid crystal display panel of FFS display pattern, public electrode and pixel electrode layering setting, work as public electrode
Positioned to above electrode, when close to liquid crystal layer setting, public electrode setting is cracked, when pixel electrode is located at public electrode top,
When close to liquid crystal layer setting, pixel electrode setting is cracked.For the liquid crystal display panel of IPS display pattern, public electrode and picture
Plain electrode same layer setting, the two, which all has, cracks, mutually nested setting.
In liquid crystal display panel described in the embodiment of the present application, does not change to crack hierarchical relationship is set and quantity of cracking,
Liquid crystal display panel, which has, to crack in design basis, is only through the extending direction for changing and cracking, so that in same pixel unit,
Cracking at least two sub-pixels is not parallel, to adjust the transmitance of the sub-pixel, does not change the knot of black matrix" in this way
Structure does not change the quantity of cracking of show electrode and public electrode, does not change the strip electrode quantity of pixel electrode.And it is only
Change the extending direction to crack, so that cracking at least two sub-pixels is not parallel, it is only in original formation in manufacture craft
The direction cracked is adjusted in the processing step cracked, does not increase processing step, and manufacture craft is simple, does not increase cost of manufacture.
