Plain electrode 133 is overlapped.This little electrode can apply matching somebody with somebody for foregoing different main slit, the length of secondary slit and flange or width
Mode is put, makes the first pixel electrode 131 area that closes overlap with the first common electrode 181 less than the 3rd pixel electrode 133 and the
The overlap of three common electrodes 183 closes area.In addition, the overlap of the second pixel electrode 132 and the second common electrode 182 closes area,
And the 3rd pixel electrode 133 and the 3rd common electrode 183 overlap close area can optionally be designed as it is equal or unequal.
That is the first pixel electrode 131 conjunction area overlap with the first common electrode 181, the second pixel electrode 132 are common with second
The overlap of electrode 182 closes area and the 3rd pixel electrode 133 conjunction area overlap with the 3rd common electrode 183 can be substantially equal
It is unequal.In practical application, the first pixel electrode 131 and the first common electrode 181 are located in one first colored pixels, second
The common electrode 182 of pixel electrode 132 and second is located in one second colored pixels, and the 3rd pixel electrode 132 and the 3rd is common
Electrode 183 is located in one the 3rd colored pixels.
Liquid crystal display panel 150 can be divided into according to the presence or absence of common electrode or pixel electrode：One first kind region, is
The region of electrode is respectively provided with one substrate 151 and second substrate 152；One Second Type region, is wherein first substrate 151 or the
For electrode, another substrate is the region of time slit on two substrates 152；And, one the 3rd type area, be first substrate 151 and
The region of time slit is on second substrate 152.Below with the first pixel electrode 131 and the first common electrode 181 in Fig. 6
As a example by be simulated.Fig. 9 A~9C is refer to, its different type area for illustrating the first pixel electrode and the first common electrode respectively
Domain carries out the voltage-breakthrough curve figure (V-T curve diagram) when color shows.When the first pixel electrode 131 and first
Common electrode 181 is when showing red, as shown in Figure 9 A, the slope reality of the voltage-breakthrough curve R1 in first kind region
In matter more than Second Type region voltage-breakthrough curve R2, and the voltage-breakthrough curve R2 in Second Type region slope reality
More than the voltage-breakthrough curve R3 of the 3rd type area in matter.Secondly, when the first pixel electrode 131 and the first common electrode 181
When being used to show green, as shown in Figure 9 B, the slope of the voltage-breakthrough curve G1 in first kind region is substantially greater than Equations of The Second Kind
The voltage in type region-breakthrough curve G2, and the slope of the voltage-breakthrough curve G2 in Second Type region is substantially greater than the 3rd class
The voltage in type region-breakthrough curve G3.Furthermore, when the first pixel electrode 131 and the first common electrode 181 are used to show blueness
When, as shown in Figure 9 C, the slope of the voltage-breakthrough curve B1 in first kind region is substantially greater than the electricity in Second Type region
Pressure-breakthrough curve B2, and the slope of the voltage-breakthrough curve B2 in Second Type region is substantially greater than the electricity of the 3rd type area
Pressure-breakthrough curve B3.
From above-mentioned analog result, when in the first pixel electrode 131 and the first common electrode 181 first and the 3rd lead
When area shared by slit 161 and 163 and first and third time slit 171 and 173 increases, the slope of voltage-breakthrough curve subtracts
It is small, that is, essentially decreased its of its grey scale curve is located at position in grey scale curve figure.In the present embodiment, due to the first pixel electricity
The overlap of the common electrode 181 of pole 131 and first closes area less than the second pixel electrode 132 and the overlap of the second common electrode 182
Area is closed, and area is closed less than the overlap of the 3rd pixel electrode 133 and the 3rd common electrode 183, therefore correspond to the first picture
First colored pixels of the common electrode 181 of plain electrode 131 and first, the slit area with maximum specific weight.In the present embodiment
One pixel electrode 131 is illustrated as a example by showing blueness, compared to the slit occupied area in traditional three colored pixels
The equal situation of ratio, blue voltage-breakthrough curve has less oblique in the liquid crystal display device 100 of the present embodiment
Rate, it is located at relatively low position in grey scale curve figure.In this way, same gray scale can be had compared with high-penetration rate red light and
Green light and same gray scale and the blue light with relatively low penetrance is arranged in pairs or groups so that white light has identical when different gray scales are spent
Colour temperature, reaches the effect of the colour temperatures such as full gray scale.
On the other hand, first switch element 121 and second switch element 122 are respectively a thin film transistor (TFT) in the present embodiment
(thin film transistor；TFT).Liquid crystal display panel 150 further includes one first storage capacitors (storage
capacitor；) and one second storage capacitors Cst.First storage capacitors are electrically connected with the first pixel electrode 131, the second storage
Depositing electric capacity is electrically connected with the second pixel electrode 132.In general, when picture display is carried out, because pixel voltage is being swept
Retouching after line is closed can produce a feed-trough voltage (feedthrough voltage) so that the liquid positioned between two substrates 151 and 152
Brilliant 153 (being illustrated in Fig. 1) experience voltage decline.This voltage declines size and liquid crystal capacitance (liquid crystal
capacitor；Clc), electric capacity (gate-drain capacitor between storage capacitors and gate-to-drain；Cgd it is) relevant, its expression
Formula isWherein Vgh is voltage when grid is opened；Vgl is electricity when grid is closed
Pressure.Because the area ratio of slit in the first colored pixels that blueness is shown in the present embodiment is more than red and green
Colored pixels, cause the liquid crystal capacitance in the first colored pixels to be less than red and green.Additionally, according to relationship below：To maintain the first color picture
Feed-trough voltage in element, the second colored pixels and the 3rd colored pixels is certain value, storage capacitors and grid in each colored pixels
Electric capacity need to have different designs between gate-drain.Illustrated below for two kinds of situations：
First, when each colored pixels storage capacitors to liquid crystal capacitance ratio is certain value when, because the first colored pixels are (aobvious
Show blueness) liquid crystal capacitance and the first storage capacitors be respectively less than remaining colored pixels (display red and green), therefore first
Storage capacitors are less than red and green and electric between gate-to-drain in the first colored pixels with the conjunction of liquid crystal capacitance in colored pixels
Rong Yixu is less than electric capacity between the gate-to-drain in the second colored pixels and the 3rd colored pixels, to maintain certain feed-trough voltage.
That is, electric capacity is less than second between the gate-to-drain of first film transistor in the present embodiment in the first colored pixels
Electric capacity between the gate-to-drain of thin film transistor (TFT)；
Secondly, when each colored pixels storage capacitors to liquid crystal capacitance ratio be non-definite value when, three colored pixels maintain it is identical
The condition of feed-trough voltage is that indivedual (Cst+Clc)/Cgd are identical.Due to the liquid crystal electricity of the first colored pixels (display is blue)
Hold less than red and green, thus it is identical to (Cst+Clc)/Cgd ratios of each colored pixels, can respectively adjust its storage
Capacitance size between electric capacity and gate-to-drain, completely depending on demand.
Generally speaking to maintain certain feed-trough voltage, and the storage capacitors of each colored pixels are one to liquid crystal capacitance ratio
During definite value, electric capacity must be designed to the blue colored pixels minimum of display between gate-to-drain；If storage capacitors are to liquid crystal capacitance ratio
Non- definite value, then can respectively adjust electric capacity between the storage capacitors and gate-to-drain of each colored pixels depending on demand.
Above-mentioned liquid crystal display panel according to present pre-ferred embodiments and its liquid crystal display device is applied, be using not
With the mode that the ratio shared by the slit that the electrode in colored pixels has in different area, and different colours pixel is differed,
Making the grey scale curve of different colours pixel can be collocated with each other compensation, allow display picture to have substantial phase in different white grays
Same colour temperature, reaches the effect of the colour temperatures such as white full gray scale, lifts the display quality of product.Additionally, using the side of electrode lay-out
Formula reduces the effect of color temperature shift to reach, the memory span needed for can reducing the display gray scale for changing different colours respectively,
Can reduces cost.
