Description
[technical field]
The present invention relates to a kind of liquid crystal indicator, relate in particular to a kind of multidomain vertical orientation (Multi-domain Vertical Alignment, MVA) mode liquid crystal indicator.
[background technology]
Liquid crystal in the liquid crystal indicator itself is not had a characteristics of luminescence, realizes passing through or not passing through of light by adopting the electric field controls liquid crystal molecule to reverse, thereby reaches the purpose of demonstration.In traditional liquid crystal indicator, form electrode on the surface of two substrate of glass, to form the electric field that the control liquid crystal molecule reverses, this electrode uses transparent material, and the electrode of two substrates is oppositely arranged, thereby forms and the perpendicular electric field of substrate surface.Because liquid crystal molecule has electrically, therefore under the control of this electric field, liquid crystal molecular orientation will be perpendicular to substrate surface, but because the influence of interaction force between liquid crystal molecule and physical force such as gravity, make that the orientation of liquid crystal molecule can not be fully perpendicular to substrate surface, and the angle of inclination of each liquid crystal molecule is not quite similar, thereby, when the observer observes from different perspectives, will observe different display effects, this is the visual angle defective of liquid crystal indicator.
The liquid crystal indicator of multidomain vertical orientation mode disperses the orientation of the liquid crystal molecule of zones of different by a pixel cell is divided into a plurality of zones, enlarges the overall viewing angle of this pixel, thereby reaches the viewing angle characteristic that improves this liquid crystal indicator.
A kind of prior art multidomain vertical orientation mode liquid crystal indicator sees also No. the 01st, 121,750, disclosed Chinese patent application on January 23rd, 2002, as Fig. 1 and shown in Figure 2.This multidomain vertical orientation mode liquid crystal indicator 1 comprises first substrate 11 and second substrate 12 that are oppositely arranged, be separately positioned in this first substrate 11 and second substrate 12 and the interlaced projection that is arranged in parallel 111 and 121, a plurality of liquid crystal molecule 16.In addition, this multidomain vertical orientation mode liquid crystal indicator 1 also comprises pixel electrode, common electrode, alignment film, thin film transistor (TFT) (Thin Film Transistor, TFT), phase compensation film and polarizing appliance etc., still, this assembly is not all shown in Fig. 1 and Fig. 2.
In second substrate 12, form the pixel electrode that is connected to this thin film transistor (TFT), in first substrate 11, form common electrode, this projection 111 is arranged on this common electrode, this projection 121 is arranged on this pixel electrode, enclose a plurality of liquid crystal molecules 16 in this first substrate 11 and 12 of second substrates, this liquid crystal molecule 16 is that specific inductive capacity is negative and anisotropic liquid crystal material, because of the restraint of alignment film makes the original alignment of liquid crystal molecule 16 be approximately perpendicular to this first substrate 11 and second substrate 12.
Please consulting Fig. 1 again, is not during making alive, the synoptic diagram of this multidomain vertical orientation mode liquid crystal indicator 1 duty of living in.Under this state, thin film transistor (TFT) is the OFF state, liquid crystal molecule 16 orientations of projection 111 and 121 s' gap area are approximately perpendicular to this first substrate 11 and second substrate 12, near the orientation of the liquid crystal molecule 16 this projection 111 and the projection 121 is approximately perpendicular to the inclined-plane of this projection 111 and 121, because when light transmits along molecular axis (being the optical axis of the liquid crystal molecule) direction of liquid crystal molecule 16, can not produce birefringence, be that its polarization state can not change, vertical mutually because of being separately positioned on this first substrate 11 again with the polarizing axis of two polarizing appliances of second substrate 12, so this moment, this multidomain vertical orientation mode liquid crystal indicator 1 was in dark attitude.
Please consult Fig. 2 again, when being making alive, the synoptic diagram of this multidomain vertical orientation mode liquid crystal indicator 1 duty of living in.Under this state, thin film transistor (TFT) is the ON state, apply electric field on the liquid crystal molecule 16 perpendicular to first substrate 11 and second substrate 12, because liquid crystal molecule 16 is specific inductive capacity is negative and anisotropic liquid crystal material, under the electric field action, this liquid crystal molecule 16 will be added the restriction of projection 111 and 121 to the direction deflection vertical with direction of an electric field, make the orientation of all liquid crystal molecules 16 of 12 of this first substrate 11 and second substrates be approximately perpendicular to the inclined-plane of this projection 111 and 121.At this moment, there is certain angle in the molecular axis direction of incident light and liquid crystal molecule 16, thereby, this polarization of incident light attitude will change, therefore, part light will be arranged from being arranged on the polarizing appliance outgoing of this first substrate 11, promptly this multidomain vertical orientation mode liquid crystal indicator 1 is in bright attitude.
Seeing also Fig. 3, is thin film transistor (TFT) when being the ON state, the vergence direction synoptic diagram of the liquid crystal molecule 16 in the pixel region of this multidomain vertical orientation mode liquid crystal indicator 1.The part that this projection 111 and 121 is positioned at this pixel region all is " ㄑ " shape projection structure, pixel electrode 14 is arranged on the transparency electrode in this second substrate 12, and each pixel region is divided into the three lengthwise subpixel area (not indicating) of red, green, blue.In each subpixel area of this multidomain vertical orientation mode liquid crystal indicator 1, this first substrate 11 is divided into A, B, C, D four zones with 12 projections 111 of second substrate and 121 formed gap areas, and the orientation of the liquid crystal molecule in each zone roughly differs 90 degree mutually.Thereby when thin film transistor (TFT) was the ON state, the liquid crystal molecule 16 of this multidomain vertical orientation mode liquid crystal indicator 1 was oriented on a plurality of directions, so the visual angle is enlarged.
But, this A, B, C, D four zones form a juncture area (not indicating), this juncture area is the corner near zone of " ㄑ " shape projection structure, because this juncture area is this A, B, C, D four-range critical zone, so, when thin film transistor (TFT) is the ON state, can't be identical with the orientation that the liquid crystal molecule 16 of this juncture area occurs being positioned at liquid crystal molecule 16 orientations in this A, B, C, a certain zone of D four-range.Again because in this multidomain vertical orientation mode liquid crystal indicator 1, by being set, projection 111 and 121 controls liquid crystal molecule 16 tilted alignments, thereby, the tilting action of liquid crystal molecule 16 is propagated to gap area near projection 111 and 121, so, when thin film transistor (TFT) was the ON state, the liquid crystal molecule 16 that is positioned at this juncture area may not run-off the straight orientation.Because when thin film transistor (TFT) is the ON state, this multidomain vertical orientation mode liquid crystal indicator 1 is in bright attitude, so, be in this moment in the viewing area of bright attitude and can have dark areas, thereby quality is drawn a portrait in influence.
In addition, because in this A, B, C, D four zones, the orientation of all liquid crystal molecules 16 in the arbitrary region is roughly the same, promptly when thin film transistor (TFT) is the ON state, the liquid crystal molecule 16 of this multidomain vertical orientation mode liquid crystal indicator 1 only roughly is oriented on four orthogonal directions, thereby, can't make the observer when all angles are observed, obtain identical portrait effect, therefore, still there is certain visual angle defective in this multidomain vertical orientation mode liquid crystal indicator 1.
[summary of the invention]
For overcoming the defective of prior art multidomain vertical orientation mode liquid crystal indicator viewing angle characteristic and portrait inferior quality, the invention provides a kind of multidomain vertical orientation mode liquid crystal indicator with preferable viewing angle characteristic and portrait quality.
