It is each provided with the step surface for having difference in height；, the pixel electrode 3 is formed with stair-step corresponding with the step surface
Face.
Pixel electrode 3 of the invention includes that ladder platform terrace thus produces because pixel electrode 3 includes ladder platform terrace
The effect for dividing picture element region has been given birth to, can improve that picture element region polarization direction caused by phase grating effect is identical but phase
Different problems, corresponding complementary, or even enable to each picture element region phase while polarization direction is identical also identical；From
And make transparent display panel in picture element penetrance when penetrating mode, is improved, improve background frame whiting or colour cast problem,
So as to improve the background frame quality of penetration display panel.
It is penetrated with more quadrant vertical orientations (Multi-domain Vertical Alignment, MVA) mode to design
When formula display panel, in order to promote the angular field of view that picture is shown, the liquid crystal in display panel is often in a manner of multiple regions
It is arranged, still, the arrangement mode of this multiple liquid crystal region can make panel generate phase grating (Phase Grating) effect
It answers, and then influences the background frame quality (such as image blur) of penetration display panel.Here, phase grating effect refers to,
When the light that different liquid crystal regions project passes through polaroid, their polarization direction is identical but phase is different.
Therefore, ladder platform terrace can make the landform that different gradients are formed between pixel electrode 3 and public electrode 2, lead to
The different gradient landform that pixel electrode 3 is formed from public electrode 2 are crossed, so that existing between pixel electrode 3 and public electrode 2
Phase delay, it is identical but phase is different that phase delay is conducive to picture element region polarization direction caused by improving phase grating effect
The problem of, corresponding complementary, or even enable to each picture element region phase while polarization direction is identical also identical.
In one embodiment of this invention, wherein step surface includes first step 421, second step 422 and third platform
Rank 423, first step 421, second step 422 and third step 423 and the spacing of public electrode 2 are gradually reduced.Certainly, such as
The design architecture of fruit panel is different, and spacing is sequentially increased also possible, as long as meeting design requirement, makes it possible to pass through phase
Postpone and make polarization direction identical and the different transmission region of phase, tends to that polarization direction is identical and phase also identical target
?.
Horizontal public electrode 2 is formed on first substrate 11, pixel electrode 3 is formed in the second substrate 12, same
Color blocking unit 40 includes first step 421, second step 422 and third step 423, and first step 421, second step
422 and third step 423 show step difference, and because pixel electrode 3 ladder platform terrace and first step, second step
And third step is corresponding, so that forming multiple picture element transmission regions between pixel electrode 3 and public electrode 2, and multiple picture elements
Transmission region there are phase delay, such setting can improve picture element region polarization direction caused by phase grating effect it is identical but
It is phase different problems, corresponding complementary, or even enable to each picture element region phase while polarization direction is identical
It is identical, so that transparent display panel is in when penetrating mode, picture element penetrance is improved, improves background frame whiting or color
Inclined problem, so as to improve the background frame quality of penetration display panel.
In one embodiment of this invention, wherein stair-step face includes first cascaded surface corresponding with first step 421
31, and corresponding second cascaded surface 32 of second step 422 and third cascaded surface 33 corresponding with third step 423, the first rank
Tread 31, the second cascaded surface 32 and third cascaded surface 33 successively form the first picture element transmission region 311, the with public electrode 2
Two picture element transmission regions 321 and third picture element transmission region 331.
First cascaded surface 31, the second cascaded surface 32 and third cascaded surface 33 and public electrode 2 sequentially form the first picture element
Transmission region 311, the second picture element transmission region 321 and third picture element transmission region 331.Corresponding first picture element transmission region
311, the second picture element transmission region 321 and third picture element transmission region 331, are sequentially reduced with the spacing of public electrode 2.Three
Picture element transmission region can generate phase difference, the phase difference generated using three picture element transmission regions, so that three sections of phase delays, right
Answer complementation, such setting can improve that picture element region polarization direction caused by phase grating effect is identical but phase is different to ask
Topic, or even enable to each picture element region phase while polarization direction is identical also identical；So that transparence display face
Plate improves picture element penetrance in when penetrating mode, improves background frame whiting or colour cast problem, aobvious so as to improve penetration
Show the background frame quality of panel.
