Description
Technical field
The invention relates to a kind of LCD, the LCD of particularly a kind of tool multiple domain orientation
Background technology
The known dielectric anisotropy (dielectric anisotropy) of utilizing is negative negative type liquid crystal material, constitute the LCD alignment mode of vertical orientation (vertical alignment) or Equidirectional type orientation (homeotropic alignment), liquid crystal molecule was not arranged in the vertical substrate mode when cause applied voltage, so good contrast (contrast) performance can be provided.Yet vertical orientation type liquid crystal display (verticallyaligned LCD) is for forming the multiple domain segmentation effect usually, and the structure that it mated has a little light leak or multiple domain is cut apart the situation that disposes scarce capacity.
Figure 1A is a diagrammatic cross-section, shows a known multi-domain vertical alignment liquid crystal displays (multi-domainvertically aligned LCD; MVA LCD) design.Shown in Figure 1A, it is to form convex body (bump) 106 respectively on upper and lower substrate 102,104, form the vertical orientation film 108 that covers convex body (bump) 106 on it again, the tilt angle (pre-tilt angle) that the liquid crystal molecule 112 of vertical orientation is had tilt towards different directions when not applying voltage applies liquid crystal molecule 112 vergence directions behind the voltage so as to control.After applying voltage, liquid crystal layer promptly may be partitioned into the little territory of liquid crystal of the different vergence directions of a plurality of tools respectively, with the viewing angle characteristic under the GTG show state of the different viewing angles of effective improvement.Moreover, be not defined as convex body 106 as border, the territory regulation structure (regulation structure) that tilt angle is provided, also can shown in Figure 1B, on substrate 114, form concave structure 116 and also can.
Shown in Figure 1A and Figure 1B, though formation convex body 106 or concave structure 116 modes can reach the effect of making the little territory of a plurality of liquid crystal, yet, under the state that does not apply voltage (Voff), relatively penetrate light I
1And I
2Light path as can be known, be not fully vertical because of this border, territory regulation structure can cause LCD alignment, thus the inclination liquid crystal molecule of passing through penetrate light I
2Light path can have unnecessary light path difference (Δ nd ≠ 0) and cause light leak.Therefore, needing to see through the outer compensate film mode of pasting in addition eliminates light leak to improve contrast.
Fig. 2 is a diagrammatic cross-section, shows the design of another multi-domain vertical alignment liquid crystal displays.As shown in Figure 2, be used in formed cracking (slit) 206 on the transparency electrode 204 of substrate 202, the toppling direction of may command liquid crystal molecule 208 after applying voltage.Yet, form 206 the mode of cracking in electrode 204 places, must think over 206 width and two that the crack distance between 206 or the like of cracking own, otherwise to produce the strength that liquid crystal molecule 208 is toppled over not enough easily by cracking 206.Moreover, crack 206 design of this formation, the energy that causes liquid crystal molecule 208 to rotate toward left and right sides either directions equates, produces discontinuous misorientation defective (disclination) and the orientation of liquid crystal molecule 208 in the space distributed.This misorientation defect area 210 cracks in 206 tops and two of cracking 206 and forms all easily, and reduces whole light transmittance.
On the other hand, when LCD only can be used in when penetrating pattern, because of can only merely using backlight to come display frame, if in the sun or under the strong environment light source, because of external light source disturbs, the user can't pick out show image easily; Otherwise, when LCD only can be used in reflective-mode,, after leaving this strong lighting environment, promptly can't watch out image clearly because of only under strong environment light source, using.Therefore, how designing one and can utilize surround lighting or demonstration backlight simultaneously and have the LCD of the multiple domain alignment structure of avoiding above-mentioned known design shortcoming, is an important topic in fact.
Summary of the invention
Therefore, purpose of the present invention is providing a kind of LCD, and it can avoid the variety of problems of above-mentioned known multiple domain orientation design.
According to design of the present invention, a kind of LCD comprise a plurality of first and second pattern elements, with a plurality of first and second auxiliary electrodes.First and second pattern elements has opposite polarity under the same picture of an inversion driving sequential control, and respectively this first and second pattern elements all has an echo area and a transmission area.A plurality of first auxiliary electrodes connect described first pattern elements, and a plurality of second auxiliary electrodes connect described second pattern elements, wherein respectively this first and second pattern elements respectively by this second and this first auxiliary electrode to small part around to form fringe field, to produce the little territory of liquid crystal of the different liquid crystal molecules tilt directions of a plurality of tools.
Form the design of auxiliary electrode by the present invention's inversion timing control model of arranging in pairs or groups, the general thin film transistor (TFT) processing procedure of only need arranging in pairs or groups forms the auxiliary electrode that a distribution mode designs in advance more in addition, can utilize the opposite polarity between the pixel electrode that auxiliary electrode and its center on to obtain multiple domain orientation effect.Compare with known border, the territory regulation structural design of convex body (bump) or concave structure of utilizing, the present invention's each liquid crystal molecule under the state that does not apply voltage (Voff) all is vertical orientation, can avoid light leakage phenomena to produce so can not produce unnecessary light path difference (Δ nd=0).On the other hand, with be known in the electrode place and form the mode crack and compare, the present invention is by the fringe field effect that opposed polarity produced of auxiliary electrode and pixel electrode, can provide stronger lqiuid crystal molecule tipping strength, to increase the viewing area useful area and effectively to promote the whole light transmittance of LCD.
