Spacing between pole 21A and public electrode 70 is the first box thickness D1, and the spacing between pixel electrode 21B and public electrode 70 is
For the second box thickness D2, the spacing between pixel electrode 21C and public electrode 70 is third box thickness D3, pixel electrode 21D and public affairs
Spacing between common electrode 70 is the 4th box thickness D4.
It should be noted that in each pixel unit 10, the arrangement mode between pixel electrode 21 can in the present embodiment
There are many, as long as display panel can be made to form four kinds of boxes thickness, the present embodiment by the first film layer 61 and the second film layer 62
It to this and is not specifically limited, only with the arrangement of pixel electrode 21A- pixel electrode 21B- pixel electrode 21C- pixel electrode 21D
It is illustrated for mode, it is subsequent to repeat no more.
In some alternative embodiments, pixel unit 10 includes n sub-pixel 20；Wherein, the integer that n is >=2；Display
The most large thickness of panel is d；In each pixel unit 10, display panel forms m kind box thickness by transparent organic film 60；Its
In, m=n, the thick difference of box is d/n.That is, display panel, in each pixel unit 10, the thick difference of box between sub-pixel 20 is identical,
So that display panel can have preferable display effect.
Specifically, please continue to refer to shown in Figure 10 and Figure 11, in each pixel unit 10, pixel electrode 21D with it is public
Spacing between electrode 71 is maximum namely the 4th box thickness D4 is most large thickness d, so that display panel passes through transparent 60 shape of organic film
At 4 kinds of box thickness, the thick difference of box is d/4, and in the case where D1 < D2 < D3 < D4, D1 can be d/4, and D2 can be d/2, and D3 can be with
For 3d/4.
The box thickness of display panel can be designed as m kind according to actual needs, and the value of m is bigger, and display panel can be shown
The grayscale shown is also more, and display effect is also better.Wherein, the specific value of the integer that m is >=2, m can be saturating by controlling
The deposition thickness of bright organic film 60 controls, so that the display effect of display panel can satisfy actual demand.
In some alternative embodiments, it please refers to shown in Figure 12, the second substrate further includes metal layer 42 and insulating layer 43；
Metal layer 42 includes data line D；Insulating layer 43 is between metal layer 42 and pixel electrode 21, and transparent organic film 60 and insulation
Layer 43 is arranged with material with film layer.
In the present embodiment, since transparent organic film 60 and insulating layer 43 are arranged with material with film layer, so as to deposit
The film layer where transparent organic film 60 is deposited while insulating layer 43, then passes through each pixel electrodes of technology controlling and process such as etching again
The thickness of 21 corresponding transparent organic films 60.Such as when forming the first box thickness D1 and the second box thickness D2, if the two
The thick difference of box is the deposition thickness of transparent 60 place film layer of organic film, and the second box thickness D2 is greater than the first box thickness D1, then only needs to etch
Fall in the second place box thickness D2 sub-pixel 20, the corresponding partially transparent organic film 60 of pixel electrode 21, it can be according to box thickness
Etch quantity for needing to control certain a part of insulating layer 43 of control, it is thick to obtain different box, advantageously reduce technology difficulty and
Process costs improve the production efficiency of display panel.
In some alternative embodiments, incorporated by reference to shown in reference Figure 13, Figure 14 and Figure 15, viewing area AA further includes multiple
The grid T1 and scan line G of thin film transistor (TFT) T, thin film transistor (TFT) T are electrically connected, the source electrode T2 and data line D electricity of thin film transistor (TFT) T
Connection, drain electrode T3 and pixel electrode 21 electrical connection of thin film transistor (TFT) T.To control leading for thin film transistor (TFT) T by scan line G
Whether logical, the display of picture is realized.
It should be noted that thin film transistor (TFT) T is generally divided into N-type transistor and P-type transistor, N-type transistor is in high electricity
It is connected under the control of ordinary mail number, ends under the control of low level signal；P-type transistor is then led under the control of low level signal
Lead to, end under the control of high level signal, the present invention is to this and is not specifically limited.
Optionally, incorporated by reference to shown in reference Figure 14, Figure 15, Figure 16 and Figure 17, scan line G includes at least two strip scan lines
g；In each pixel unit 10, the grid T1 of thin film transistor (TFT) T and strip scan line g electrical connection.
In the present embodiment, by taking scan line G includes two sub-pixels 20 including two strip scan line g, pixel unit 10 as an example,
Whether two strip scan line g individually control the conducting of corresponding thin film transistor (TFT) T, since thin film transistor (TFT) T is only in conducting
In the case of, data line D is just that corresponding pixel electrode 21 provides electric signal, so that the grayscale difference of pixel unit 10 on the one hand can
To be controlled by the deposition thickness of transparent organic film 60, on the other hand can also be led by thin film transistor (TFT) T in pixel unit 10
Logical quantity control, further increases the grayscale that display panel can be shown, improves the display effect of display panel.
