Description
Technical field
The invention relates to a kind of display panels (liquid crystal display panel), and particularly relevant for a kind of display panels with good display quality.
Background technology
Existing market all develops towards height contrast (contrastratio), the counter-rotating of no GTG (gray scale inversion), high brightness (brightness), high color saturation (colorsaturation), rapid reaction (response) and wide viewing angle directions such as (viewing angle) for Thin Film Transistor-LCD (TFT-LCD).Common wide viewing angle technology comprises at present: stable twisted nematic liquid crystal (TN) adds view film (wide viewingfilm), copline suitching type (In-Plane Switching, IPS) LCD, a limit suitching type (Fringe Field Switching, FFS) LCD and multi-zone vertical alignment nematic (Multi-domainVertical Alignment, MVA) LCD.With the multifield vertical directional liquid crystal display panel is example, it can be by some alignment pattern (alignment patterning), as orientation protrusion (alignmentprotrusion) or slit (slit), so that the liquid crystal molecule in each pixel is multi-direction arrangement, and then obtain several different orientation fields (domain).For existing multifield vertical directional liquid crystal display panel, because the orientation protrusion (alignment protrusions) or the slit (slits) that are formed on colored optical filtering substrates or the plurality of groups of substrates of thin-film transistor can be so that liquid crystal molecule be multi-direction arrangement, and obtain several different orientation fields (domains), so multifield vertical directional liquid crystal display panel can be reached the requirement of wide viewing angle.
Look synoptic diagram on the existing a kind of multifield vertical directional liquid crystal display panel of Fig. 1.Please refer to Fig. 1, in existing semi-penetration, semi-reflective multifield vertical directional liquid crystal display panel 100, can be provided with a plurality of orientation protrusion P on its colored optical filtering substrates, and these orientation protrusions P can be distributed in reflecting electrode Re and through electrode Tr top.And have main slit (main slit) SS in the middle of reflecting electrode Re and the through electrode Tr, its objective is that the liquid crystal LC that makes through electrode Tr and reflecting electrode Re edge topples over toward orientation protrusion P.Because orientation protrusion P is the centre that is arranged at reflecting electrode Re and through electrode Tr, it can change the distribution of line of electric force, and liquid crystal LC is toppled over toward orientation protrusion P direction, to reach the purpose of wide viewing angle.In addition, also have connection electrode C between reflecting electrode Re and through electrode Tr so that reflecting electrode Re and through electrode Tr be electrically connected to each other, this connection electrode C can with reflecting electrode Re or the identical electrode material of through electrode Tr.General semi-penetration, semi-reflective multifield vertical directional liquid crystal display panel 100 can adopt spherical gap (ball spacers) to keep its gap (cell-gap); the shortcoming of this practice is the problem that there is dark attitude light leak in the regular meeting on every side in spherical gap, causes the contrast of semi-penetration, semi-reflective multifield vertical directional liquid crystal display panel 100 to descend.In addition, in present semi-penetration, semi-reflective multifield vertical directional liquid crystal display panel 100, also there is the sub-PS in light gap that uses on the colored optical filtering substrates to keep the design in its gap.Generally speaking, the sub-PS in light gap utilizes organic material to make, and the problem that has dark attitude light leak on every side equally of the sub-PS in light gap.
And because spherical gap or the sub-PS in light gap can't avoid the problem of dark attitude light leak, therefore the position that disposed of spherical gap or the sub-PS in light gap becomes very important.With the sub-PS in light gap on the colored optical filtering substrates is example, for fear of the problem of dark attitude light leak, can a platform (stage) 110 be set on plurality of groups of substrates of thin-film transistor usually, so that the sub-PS in light gap can stably stand on the platform 110.Can know by Fig. 1 and to learn; the sub-PS in light gap can design usually above data line DL; to reduce the influence for aperture opening ratio (aperture ratio) of sub-PS in light gap and platform 110 as far as possible, still, the setting of platform 110 still can cause aperture opening ratio significantly to reduce.
Summary of the invention
The invention provides a kind of display panels, it has the good optical performance.
The invention provides a kind of display panels, the effective display area of its each sub-pixel is equal in fact.
The invention provides a kind of display panels, comprise that one first substrate, is disposed at second substrate, many signal wires that are disposed on first substrate of first substrate top, and many groups are arranged in sub-pixel between first substrate and second substrate, wherein respectively organize sub-pixel and comprise a plurality of sub-pixels that electrically connect with signal wire, each sub-pixel has at least one alignment pattern that is positioned at sub-pixel inside, and the alignment pattern of respectively organizing one of them the sub-pixel inside in the sub-pixel is to be supported between first substrate and second substrate, with as gap.
The invention provides a kind of display panels, comprise that one first substrate, is disposed at second substrate, many signal wires that are disposed on first substrate of first substrate top, and many groups are arranged in the sub-pixel between first substrate and second substrate.Each is organized sub-pixel and comprises a plurality of sub-pixels that electrically connect with signal wire, has gap that is supported between first substrate and second substrate and respectively organize sub-pixel, and each gap can form a zone respectively organizing of correspondence in the sub-pixel, the area that wherein has the sub-pixel in zone can be greater than other sub-pixel, and the effective display area with the sub-pixel in zone can equate in fact with the effective display area of other sub-pixel.
Because the present invention adopts gap with orientation function to replace alignment pattern in the parton pixel, so the configuration of gap can not make sub-pixel additionally lose aperture opening ratio.And the deviser can will have the area increasing (greater than the area average of sub-pixel) of this regional sub-pixel according to demand, and reduce the area (less than the area average of sub-pixel) of other sub-pixel, equate in fact with the effective display area of other sub-pixel so that have the effective display area of this regional sub-pixel, and then make display panels have good display quality.
