Description
Technical field
The present invention relates to technical field of liquid crystal display, particularly a kind of display panels and comprise its device.
Background technology
Liquid crystal indicator is to utilize the optical anisotropy of liquid crystal molecule and the device that birefringent characteristic comes displayed image.In the display panel of liquid crystal indicator, two transparent insulation substrate surperficial positioned opposite to each other, and be formed with electrode described two substrates apparent surface, between substrate, have liquid crystal material.By electrode application voltage to described substrate surface, produce the orientation that electric field changes liquid crystal molecule, thereby control sees through the liquid crystal material light intensity, obtain the image of desired display.The liquid crystal indicator of above-mentioned structure generally includes thin film transistor (TFT), and (Thin Film Transistor TFT) as on-off element, puts on the voltage of described electrode with control, so also is called Thin Film Transistor-LCD (TFT-LCD).
Fig. 1 is the exploded view of the structure of existing a kind of liquid crystal panel.Please refer to Fig. 1, the liquid crystal indicator liquid crystal panel comprises upper substrate 50 and infrabasal plate 70, bonds together by frame glue (figure does not go out) between them, has predetermined space therebetween.In its space, be injected with liquid crystal layer 60.The transparent glass substrate 1 of infrabasal plate 70 (or being called first substrate 1) is provided with multi-strip scanning line 12 and many data lines 11.Multi-strip scanning line 12 is arranged with preset distance along some directions, and many data lines 11 are arranged along the direction vertical with sweep trace 12, thereby defined pixel region (pixel) 75.On the pixel region 75 on first substrate, 1 surface, be formed with pixel electrode 74.Has thin film transistor (TFT) Q (TFT) at each the bar sweep trace 12 of first substrate 1 and the infall of each bar data line 11.Optionally open and certain pixel 75 corresponding TFT by the sweep signal that sweep trace 12 applies, thereby apply the data-signal of data line 11 to the pixel electrode 74 of this pixel.
On the transparent glass substrate 2 (or being called second substrate 2) of upper substrate 50, be formed with the black-matrix layer (black matrix layer) 25 that is used to stop pixel region 75 printing opacities, also be black matrix layer.Be formed with red (R), green (G) that is used for apparent color, blue (B) color-filter layer 53 towards the surface of infrabasal plate 70 at upper substrate 50 corresponding to the zone of pixel region.On color-filter layer 53, be formed with the common electrode layer 54 that is used to drive liquid crystal display image.
For interval required between the upper and lower base plate that forms liquid crystal panel (cell gap), so on second substrate, stilt is set, this stilt is called sept (spacer), sept is generally photochromics, for example, acryl resins etc., shape can form by photoetching process for spherical, cylindricality or trapezoidal.And sept is usually located at data line and sweep trace top, does not influence displayed image, only provides the space, to prevent first and second substrate contacts.
Fig. 2 is the vertical view of the liquid crystal panel part (pixel region) of explanation sept position.Please refer to Fig. 2, data line 11 and sweep trace 12 on black matrix" 25 corresponding first substrates 1 on second substrate 2, and comprise active layer 13, source electrode 14 and 15 the thin film transistor (TFT) of draining.Drain electrode 15 is connected to pixel electrode 10 by contact hole 16.Sept 30 is positioned at sweep trace 12 tops, Fig. 3 is along the cross-sectional view of A-A ' direction among Fig. 2, as shown in Figure 3, sweep trace 12 is formed at the surface of first substrate 1, be formed with gate insulation layer 3 and passivation layer 4 successively at first substrate 1 and sweep trace 12 surfaces, second substrate, 2 surfaces are formed with black-matrix layer 25 and light color-filter layer 21 and common electrode layer (figure does not show), wherein, light color-filter layer 21 and black-matrix layer 25 marginal portions are overlapping, and sept 30 is formed at common electrode layer (figure does not show) surface above the black-matrix layer 25.Pixel electrode 10 is formed at passivation layer 4 surfaces and corresponding with the position of light color-filter layer 21.Upper and lower base plate by the frame glue bond after the height of sept 30 itself and passivation layer 4 surfaces are contacted.
But the sept that said method is arranged when applying with respect to the liquid crystal panel surface horizontal or oblique external force on the liquid crystal panel surface, as shown in Figure 4, can cause sept 30 skews, even can't get back to its origin-location.Especially when the density of sept 30 is bigger than normal, more difficult all septs 30 that make are got back to its origin-location, cause the upper and lower base plate dislocation, the light leak zone of position shown in the dotted line A1 occurs, the normal demonstration of influence image produces so-called wiping examination ghost phenomena (Push Mura).
On the other hand, when pressure vertically puts on panel, the variation in generating unit gap in the time of can causing pushing the liquid crystal panel surface, and when pressure is excessive, can damage described cylindricality sept, make that panel can not reinstatement, " the gap unevenness that pressure causes " phenomenon (below be referred to as " pressing black mura ") occurs.
