(summary of invention)

Liquid crystal panel of the present invention has reflection to showing slinkingly the light that shows part incident, sees through the function to the light that obviously shows part incident.For this reason, liquid crystal panel of the present invention is characterized in that: have liquid crystal layer, watching a side (Fig. 1 (a)) or having in both sides as the polarized light of the 1st polarization layer and select reflection horizon 303 (Fig. 1 (b)) at above-mentioned liquid crystal layer.Perhaps, have under the situation of colour filter 305, between liquid crystal layer 304 and colour filter 305, have polarized light and select reflection horizon 303 (Fig. 1 (c)) in the side of watching of liquid crystal layer.At this moment, the side of watching in polarized light selection reflection horizon 303 has the absorption polarization layer 301 as the 2nd polarization layer.As mentioned above, if use absorption polarization layer 301, improve contrast thereby then can absorb the light of selecting to have among the light in reflection horizon 303 obsolete unnecessary polarized light in demonstration through polarized light.In addition, in Fig. 1, the 300th, glass substrate, the 302nd, substrate in opposite directions.

Secondly, Fig. 2 shows and can optionally reflect in the above-described configuration or see through principle to the light of liquid crystal layer incident.In addition, in Fig. 2, the 400th, glass substrate, the 403rd, substrate in opposite directions.

Polarized light is selected reflection horizon A402, sees through the P wave reflection S ripple of linearly polarized photon within the backlight light 407,412.In addition, polarized light selects reflection horizon B405 similarly to have the characteristic that within incident light reflected P ripple sees through the S ripple.Liquid crystal layer 406 uses the phase invariantization that sees through light in black display part 415, the liquid crystal layer that carries out the PS conversion in white display part 416.For example, liquid crystal layer 406 can use the phase change of the light of vertically propagating to become substantially to be 0 liquid crystal layer when black display in liquid crystal layer.In addition, make to become such formation: absorption polarization layer A401 sees through the P ripple, and absorption polarization layer B405 sees through the S ripple.

Within the backlight light 407 that incides on the black display part 415, S ripple 401 is reflected in polarized light selection reflection horizon A401, and P ripple 408 sees through.P ripple 408 also sees through absorption polarization layer A401, to liquid crystal layer 406 incidents.At this moment, because being absorbed formula polarization layer A401, the S ripple after seeing through absorbs, so 406 incidents of P wave direction liquid crystal layer.The P ripple 408 of going into to shine is selected reflection horizon B404 incident and is not modulated by liquid crystal layer 406 to the polarized light of watching a side.Therefore, light can be from the panel outgoing, thereby can obtain black display.P ripple 409 after the reflection similarly sees through absorption polarization layer A402 as the P ripple and polarized light is selected reflection horizon A401, become for P ripple 411 to backlight one side outgoing.In addition, if watching a side to dispose absorption polarization layer B405, even if then for example the part of P ripple see through polarized light and select reflection horizon B405 absorb because the P ripple after seeing through also can be absorbed formula polarization layer B405, so still can obtain black display.

At this moment, polarized light selection reflection horizon can be used for polarisation of light and be had optionally reflection horizon.For example, can use Nicol, dielectric multilayer film or holographic element.They can optionally see through or reflected P ripple and S ripple.Also can have azimuthal anisotropy on the selectivity of this external polarization.For example, select the light on the reflection horizon and the light of oblique incidence optionally degree also can be different for vertically inciding polarized light.For example, in personal digital assistant etc., be limited under the positive situation in the scope of watching, polar angle 20 degree of selecting the normal direction in reflection horizon to count from polarized light with interior scope in, also can obtain high polarized light selectivity.In addition, also can be according to anisotropy from backlight to the angular distribution design polarized light of the light of liquid crystal panel incident that select the reflection horizon from.

In addition, also can use the scattering device.For example, the scattering device that is made of the complex between liquid crystal and the polymkeric substance is owing to have azimuthal anisotropy at the match party mask of refractive index, so optionally scattering, through P ripple and S ripple.

In addition, polarized light selects layer also can use the layer of either party circularly polarized light of the reflection left and right sides.The polarized light that for example also can use in layer index distribution to have spiral structure is selected layer.Specifically, also can form spiral structure with cholesteryl liquid crystal or polymkeric substance.

On the other hand, incide the backlight light 412 on the white display part 416, similarly become incide on the liquid crystal layer 406 for P ripple 418 after, in liquid crystal layer 406, carry out becoming after the PS conversion 413 and be S ripple 417, see through polarized light as S ripple 414 and select reflection horizon B404 and absorption polarization layer B405.For this reason, can obtain white shows.

At this moment, liquid crystal layer 406 subtend polarized lights select the polarized state of light of reflection horizon B404 incident to control, and have both optionally function that realizes reflecting ﹠ transmitting and the function that shows.

In addition, use under the situation of absorption colour filter watching a side, if being set, polarized light selects reflection horizon B404 between liquid crystal layer 406 and colour filter, then in black display part 415, light is not absorbed by colour filter, select among the B404 of reflection horizon at polarized light, complete substantially light quantity is reflected to backlight one side.

As the driving method of panel, also can use the driving method that in image duration, inserts black display during constant.As LCD, in the display device of maintenance, when in image duration, inserting black display, then have to show and reduce visual conditions of streaking, improve the effect of answer speed.But, in the prior art, exist because of inserting the problem that black display makes the briliancy reduction of essence.On the other hand, under the situation that the present invention constitutes, when the black display of pixel, because the light that incides on the pixel can be propagated to white display part, even if carry out the insertion of above-mentioned black display, also can obtain the effect that the white briliancy that shows does not reduce so use.

The 1st liquid crystal indicator of the present invention, employing, make to showing slinkingly the light circulation of showing part incident to be used for obviously showing partly the way that imports the liquid crystal layer that obviously shows part to the light that shows slinkingly the liquid crystal layer incident of showing part with light-guiding mechanism, realize the peak value briliancy.

At first, with Fig. 3 the displaying principle that realizes the peak value briliancy is described.

When Fig. 3 (a) shows and exists white and black displays in the picture top, incide the backlight light on the black display part, circulation is to the principle of white display part incident in light conductor 700 grades.

Have through the P ripple of polarized light and reflect the liquid crystal panel that S wave polarization light is selected reflection horizon A700 and had upper and lower base plate and liquid crystal layer 716 at light conductor 700 top laminations, see through the S wave reflection P wave polarization light selection reflection horizon B703 of polarized light again at the upper surface lamination of upper substrate 702.

In addition, liquid crystal layer 713 uses such liquid crystal layer: do not change by polarized state of light when black display, have when white shows and make polarized light carry out the orientation of PS conversion 712.

At this moment, seen through polarized light and selected the P ripple 705 of reflection horizon A700, also can keep the P ripple even if see through the liquid crystal layer of black display part 707.Therefore, P ripple 705 is selected reflection horizon B704 reflection by the polarized light of upper surface, becomes to be reflected light 710, after having seen through polarized light once more and selecting reflection horizon B704, becomes to propagates light and propagates in light conductor 700.Once more to the light of black display part 707 incidents,, in light conductor 700, circulate once more within from the emergent light of light conductor 700 for the said reason in top.

On the other hand, shine the light on the white display part 708, in liquid crystal layer 716, carry out PS conversion 712, become to selecting reflection horizon B704 incident to polarized light in S ripple 706 backs.At this moment, because the S ripple will be selected reflection horizon B704 through polarized light, be emergent light A714 so will become.Adopt the way of using above-mentioned formation, incide the light on the black display part, just can in light conductor 700, propagate, from the outgoing of white display part not to observer's one side outgoing.For this reason, the display area of white display part is more little, shows that then briliancy is just high more, thereby the peak value briliancy will take place.

Fig. 3 (b) shows in the picture top and exists under the situation of medium tone display part 709, and incident light carries out light round-robin principle.Under the situation that medium tone shows, in that moment of having passed through liquid crystal layer 716, light has elliptically polarized light 717.At this moment, the component of the S ripple 706 of elliptically polarized light becomes and is the emergent light outgoing, carries out medium tone and shows.In addition the remaining P wave component of elliptically polarized light 717 become for reflected light 710 to light conductor 700 1 lateral reflections.This reflected light 710 is propagated (propagates light 711) in light conductor, carry out PS conversion 712 in white display part 708, becomes to be outgoing behind the emergent light A714.

According to above-mentioned principle,, find the peak value briliancy even if underway tone also can carry out the light circulation when showing.

When see through the black display part carry out polarisation transformation earlier after, light makes contrast low from the outgoing of black display part.Particularly circulation light carries out under the situation of multipath reflection in liquid crystal layer, and tonal variation will take place for this, reduces watching property.Therefore, liquid crystal layer it is desirable to not carry out through the light of liquid crystal layer the liquid crystal layer of polarisation transformation when black display, specifically, can use when making alive not liquid crystal to have the display mode of anisotropy orientation, or have even orientation, can use the lateral electric field mode of the transverse electric field driving parallel etc. with substrate.In addition, under the situation of 90 degree twisted nematic modes, it is desirable to use under the normality white display mode, making when black display polarisation transformation become substantially is 0.In addition, as liquid crystal layer, also can use mixed orientation or ocb mode.Ocb mode particularly is because answer speed near several ms, is effective so carry out the driving of above-mentioned black insertion.

Adopt the way of using above-mentioned formation, when the polarization state that can use liquid crystal layer shows, can also select the polarization of reflection horizon B to select to carry out the light circulation by means of the polarized light of upper surface one side.

As liquid crystal panel, can also use the panel of infiltration type and semi-transmission type.

The peak value briliancy of white display part is carried out the decision of light round-robin light quantity by black display or medium tone display part.Therefore, the black display part is many more in picture, and then the peak value briliancy of white display part is just high more.In addition, the briliancy of medium tone display part is more near black level, and the emergent light to the view direction outgoing in the medium tone display part is just few more, and as a result of carrying out light round-robin light quantity to white display part just increases more.Therefore, the briliancy grade of medium tone display part is more near black level, and the briliancy grade of white display part approaches white more, and then the peak value briliancy just increases more.

In Fig. 3, polarized light is selected reflection horizon B704, is applied on the upper substrate 703.On the other hand, install in color filter under the situation on the upper substrate 703, the absorbing light in color filter can not be carried out the light circulation.For this reason, polarized light select reflection horizon B704 also must in install on the colour filter.

The feature of the 2nd liquid crystal indicator of the present invention is: adopt by means of light-guiding mechanism the light that incides on the liquid crystal layer is transformed into the way that sees through the light of above-mentioned liquid crystal layer with the optical path length that differs from one another, make the light with a plurality of phase places to same direction outgoing.At this moment, the feature of light-guiding mechanism is to select the reflection horizon to constitute by liquid crystal layer and polarized light.By means of this formation, the polarized state of light that sees through liquid crystal layer averages out, and can suppress the generation of briliancy counter-rotating.Fig. 4 is a schematic diagram.When medium tone shows, exist emergent light A1209 that once sees through liquid crystal layer and the emergent light B1210 that in polarized light selection reflection horizon up and down, reflects the back outgoing.This is because when medium tone shows, has S ripple and P ripple owing to mix in whole liquid crystal layer, will light and catoptrical cause take place to see through with certain ratio under the situation in polarized light selection reflection horizon.At this moment, the optical path length of emergent light B1210 in liquid crystal layer 1208 becomes 2 times for emergent light A1209.Therefore, when watching, the result just becomes to emergent light A1209 and emergent light B1210 average out, thereby the effect of the briliancy grade counter-rotating that particularly can be reduced.In addition, the 1200th, glass substrate, the 1201st, polarized light is selected reflection horizon A, and the 1202nd, absorption polarization layer A, 1203 and 1204 is transparency electrodes, the 1205th, substrate in opposite directions, the 1206th, polarized light is selected reflection horizon B, the 1207th, absorption polarization layer B, the 1208th, liquid crystal layer.

Secondly, concrete form below is described.

Have polarized light in the both sides of liquid crystal layer 304 and select reflection horizon 303.At this moment, according to above-mentioned principle shown in Figure 1, the show state that depends on liquid crystal layer 406, make and when black display, select the light of reflection horizon B404 reflection to backlight one lateral reflection being polarized light, when when white shows, making it to see through, select A401 reflection in reflection horizon to become possibility from the S ripple within the light of backlight 407 with polarized light.For this reason, can obtain making nearly all backlight light to become to reflected light or see through light and become the liquid crystal panel that may absorb backlight light with a series of light path.

[other item]

(1) in this example, select the reflection horizon though polarized light selects reflection horizon A402 to do to become through P wave reflection S wave polarization light, it also can be that reflection S ripple is selected the reflection horizon through P wave polarization light.At that time, select polarized light reflection horizon B404 to make to become the reflected P ripple equally and see through S wave polarization light selection reflection horizon.

(2) polarized light select the reflection horizon also can for about circularly polarized light have selectivity.For example polarized light selects reflection horizon A401 can use the reflection right-hand circularly polarized light, sees through left polarisation of light light and selects the reflection horizon, and polarized light selects reflection horizon B404 also can use reflection left light, and the polarized light that sees through right-hand circularly polarized light is selected the reflection horizon.In this case, even if select the selectivity reverse about the reflection horizon makes to come also can obtain same effect with polarized light separately.

(example 4)

[formation of liquid crystal indicator and operating principle]

In the liquid crystal panel of example 1, liquid crystal layer uses the variation that sees through polarized state of light when black display to be almost 0, has to make polarized light carry out the liquid crystal layer of the orientation of PS variation when white shows.Specifically, liquid crystal layer can use liquid crystal to have negative dielectric anisotropy, has the liquid crystal layer of vertical orientation when making alive not.Have at liquid crystal layer under the situation of vertical orientation, the light of advancing on direction between substrate in liquid crystal layer is not subjected to phase modulation (PM).Therefore, for example incide original state that light on the liquid crystal layer can keep the P ripple and select reflection horizon incident to the polarized light of substrate in opposite directions unchangeably, reflection optionally takes place and see through light according to principle shown in Figure 2 with the state of P ripple.At this moment, can obtain depending on the show state of liquid crystal layer, the light that handle is polarized light selection reflective layer reflects when black display just makes it the liquid crystal panel that sees through to backlight one lateral reflection when white shows.

[other item]

(1) liquid crystal layer except that above-mentioned, also can use when making alive not liquid crystal to have the liquid crystal layer of orientation of the lateral electric field mode of even orientation.Because lateral electric field mode, the light of advancing on direction between substrate in liquid crystal layer is not subjected to phase modulation (PM) yet, so can obtain same effect.

(2) polarized light selects the reflection horizon to contain the substrate of watching a side, can be configured in the one-sided or both sides of liquid crystal layer.Principle for same with example 3 also can be provided with colour filter.

(example 5)

[formation of liquid crystal indicator and operating principle]

In the liquid crystal panel of example 1, liquid crystal layer uses when black display the variation by polarized state of light to become to be minimum, and polarized light has the liquid crystal layer of the orientation of carrying out the PS conversion when white shows.Specifically, liquid crystal layer can use twisted nematic mode, mixed mode and have the liquid crystal layer of the ocb mode etc. of crooked orientation.These liquid crystal layers adopt and apply the way that makes liquid crystal begin upwards to rise from substrate by means of voltage and become and be black display, though the phase change of the light that at this moment passes through on direction between substrate in liquid crystal layer is not 0, but becomes and are minimum.If phase change becomes and is minimum, then the result just becomes to for example incide the major part maintenance P wave direction polarized light selection reflection horizon incident of substrate one side in opposite directions of the light on the liquid crystal layer with the state of P ripple, for the said reason in top, the major part that can obtain backlight light becomes to can absorbed liquid crystal panel by light or reflected light.

(example 6)

[formation of liquid crystal indicator]

Fig. 5 is the sectional view of liquid crystal indicator of the infiltration type of example 6 of the present invention.Omitted backlight for simplicity.At the downside that liquid crystal layer 106 is clamped in the liquid crystal panel between the upper and lower base plate, diffusion layer 100, light conductor 101, polarized light are selected reflection horizon A102 on the lamination, and polarized light selects reflection horizon B105 then to be laminated to upside.In addition, in Fig. 5, the 103rd, infrabasal plate, the 104th, upper substrate.

[operating principle of liquid crystal indicator]

Within the incident light 107 from backlight, P ripple 108 components are selected reflection horizon A102 by polarized light, and S ripple 109 components then are reflected.Light after the reflection spreads to become in diffusion layer 100 and is natural light, propagates in light conductor 101.In addition, incide the light of the P ripple 108 on the black display part 112,, select reflection horizon B105 reflection, similarly in light conductor 101, propagate so be polarized light owing in liquid crystal layer, be not subjected to polarisation transformation.

In black display part 112, within the light of in light conductor, propagating, after inciding on the liquid crystal layer 106 once more successively, be polarized light and select reflection horizon B105 reflection by the P wave component that spreads 111 natural lights that form, in light conductor 101, propagate once more.

In addition, in white display part 113, incide the light of the P ripple 108 on the liquid crystal layer 106, change 110 and become and be S ripple 109, watch so can see through polarized light selection reflection horizon B105 owing to carrying out PS.For this reason, in white display part 113, can in demonstration, use the light that incides on the black display part 112, thereby the peak value briliancy takes place.

[other item]

(1) selects the reflection horizon as polarized light, can use except that selecting this P ripple and S ripple of reflection, also select the selection reflection horizon of the circularly polarized light about reflection as linearly polarized photon.In addition, polarized light is selected the reflection horizon, also can use the polarized light that absorption polarization layer is laminated on the layer that carries out the polarized light selection to select the reflection horizon.At this moment, adopt at polarized light and select the top, reflection horizon to use the way of absorption polarization layer, just can carry out the light circulation.In addition, even if the selectivity of selecting the reflection horizon to carry out with polarized light is insufficient, because non-selected polarized light is absorbed in absorption polarization layer, so can there not be black floating thing realization high-contrast.

(2) in Fig. 5, as liquid crystal layer, use be when making alive not, to have a vertical orientation, by means of adding that voltage orientation orientation 45 degree that tilt carry out the display mode that white shows.The liquid crystal layer of vertical orientation does not carry out birefringence for the light of vertically propagating with substrate, can not carry out polarisation transformation.At this moment, if the selectivity of polarized light is being intersected vertically up and down, then when making alive not, can obtain black display.

(3) no matter backlight can use any all right in side light type and the directly-below type.

Fig. 6 shows the sectional view under the situation of the backlight that uses side light type.The way that the light conductor that chien shih mainly used in the light circulation during employing was clamped in diffusion layer and the light conductor of backlight are adjacent to each other just can efficient be carried out the light circulation well.Employing is provided with the way of diffusion layer between light conductor, can be to the liquid crystal panel luminous diffusion light of the plane of incidence in fact, thereby can improve the homogeneity of briliancy in the face.

In addition, the optical loss in light conductor extremely lacks, usually below 1%.For this reason, if use the light conductor with the effect of main propagation circulation light, then propagates light can not decay, and is effective.

If light round-robin light conductor is set, then also has following effect.In general, the light conductor of backlight is provided with and is used for making backlight light equably to the sag and swell of back side of panel irradiation.For this reason, if the double light-guiding mechanism of doing circulation light of the light conductor of backlight, then circulation light is run away from the back side by the sag and swell scattering at the back side, and round-robin efficient reduces.For above reason, adopt and to use with the propagation of circulation light way as the light conductor of fundamental purpose, just can efficient realize that well light circulates.

(4) as the concrete application of liquid crystal indicator, for example, can in LCD TV, LCD monitor, personal digital assistant and mobile phone etc., use.

[concrete example 1 corresponding] with example 6

With the corresponding concrete example 1 of Fig. 6 explanation and example 6.In addition, in Fig. 6, the 205th, infrabasal plate, the 206th, upper substrate, the 211st, incident light A, the 212nd, emergent light A, the 213rd, incident light B, the 214th, emergent light B, the 215th, black display part, the 216th, white display part.

With bulb 210 propylene system light conductor A200 top in abutting connection with configuration, thin slice, lamination light conductor B202 are again spread in 201 configurations as diffusion layer.Secondly, selecting reflected P wave polarization light to select reflection horizon A203 to be laminated to light conductor B202 top.Select the reflection horizon as polarized light, the film that can use multilayer film or cholesteryl liquid crystal polymkeric substance by organic or inorganic to constitute.Secondly, absorption polaroid A 204 is configured so that to see through the P ripple.If use absorption polaroid A,, also can fully become ripple to P from backlight one side incident polarized light even if then the polarized light selectivity of selecting the reflection horizon to carry out with polarized light is insufficient.Be clamped in the liquid crystal layer 209 between upper and lower base plate, liquid crystal has vertical orientation when making alive not.For this reason, liquid crystal layer 209 does not produce polarisation transformation during making alive, and liquid crystal tilts when adding voltage, and polarized light becomes the S ripple from the P wave conversion.In upper substrate 206 tops, select the reflected P ripple to see through S wave polarization light on the lamination and select reflection horizon B207 and absorption polaroid B208.At this moment, be configured so that to see through the S ripple to absorption polaroid B208.In addition,, form transparent electrode layer, drive liquid crystal layer in the inboard of upper and lower base plate though do not draw among the figure.

Carry out white and black displays in the picture top by the border, observe the peak value briliancy that the area that is accompanied by the black display part increases the briliancy increase of white display part.

At picture central authorities display white window, the relation of the area ratio the when area ratio of change white and black displays shows and the briliancy of white display part is shown in Fig. 7.At this moment, be accompanied by the briliancy exponential function ground increase of increase white display part of the area ratio of black display.Particularly reach 80% briliancy of peak value when above and heighten, realized from 1500nit to 2000nit at area ratio.

Secondly, Fig. 8 shows the area ratio of black display is fixed as 90%, makes the position that is equivalent to black display part area show the result of the relation of research briliancy grade and peak value briliancy from black to carrying out the briliancy grade in vain.At this moment, white display part becomes the demonstration for transmitance 100%.Show slinkingly the transmitance of showing part and rise, approaching more white, the peak value briliancy just reduces more.This is because remove and show slinkingly the briliancy grade of showing and show beyond the needed light, all circulate, thereby rise the more absolute value of circulation light of transmitance just reduces the cause that the peak value briliancy reduces more.

As liquid crystal layer, remove outside the above-mentioned vertical orientation, can also use the transverse electric field display mode of normality black of even orientation or the TN pattern of STN pattern and 90 degree distortions etc. etc.

Adopt the way of using diffusion layer 201, can be used as diffused light source to the light of bulb 210, improve internal homogeneity.

As light conductor B, for example, shown in Fig. 9 (a), use to be formed obliquely layer A1300 that refractive index differs from one another and the light conductor of layer B1301.At this moment, adopt to make backlight light 1302 see through light conductor, the way of circulation light 1303 total reflection on the interface of layer is once more from upper surface one side outgoing.The light that goes out to shoot out depends on the show state of liquid crystal layer, in time to watching a side outgoing or being selected reflective layer reflects as circulation light by the polarized light of substrate in opposite directions.Adopt the way of carrying out this process repeatedly, just can make to incide to show slinkingly the light that shows in the part,, in obviously showing partly, propagate until obviously show till the part.

In addition, shown in Fig. 9 (b), adopt the way that ditch is set on the lower surface of light conductor B, just can be contained in propagates light in the ditch or make it outgoing at internal communication.At this moment, if ditch is set, then has the effect that the generation of making is contained in the light (circulation light 1307) of light conductor inside in lower surface one side.Containment light for example, can adopt the way that changes the direction of propagation with the diffusion layer etc. of lower surface one side that is arranged on ditch successively, and making becomes possibility from upper surface one side outgoing.

In addition, Fig. 9 (a) (b) in, the 1304th, light conductor, the 1305th, ditch, the 1306th, backlight light, the 1307th, circulation light.

In above-mentioned example,, also can use color filter though do not use color filter.Be equipped with in substrate under the situation of absorption color filter of pigment-dispersing type etc., polarized light select the reflection horizon must in be loaded on the inboard more inward of colour filter.This is because if the cause that absorbing light then can reduce cycle efficieny takes place in colour filter.

[concrete example 2 corresponding] with example 2

With the corresponding concrete example 2 of Figure 10 explanation and example 6.Figure 10 is the example of the transverse electric field display mode of normality black.In addition, in Figure 10, the 100th, big 1 light conductor, the 1001st, diffusion layer, the 1004th, substrate in opposite directions, the 1006th, polaroid, the 1007th, bulb, the 1008th, bulb shield, the 1011st, source electrode line, the 1012nd, gate line.

In array base palte 1003 tops with comb electrode 1014, liquid crystal has even orientation.At this moment, the orientation orientation 1010 of liquid crystal become for the 2nd light conductor 1002 in the main direction of propagation 1009 of light vertical substantially.

By means of above-mentioned formation, also parallel and see through the light of liquid crystal layer 1015 obliquely from the incident light 1016 of the 2nd light conductor 1002 with the direction of propagation even if for not only vertical to liquid crystal layer 1015 incidents, also be difficult to accept phase change.This is to be vertical substantially cause because the angle that the alignment direction 1010 of incident light 1016 and liquid crystal major axis is constituted becomes.For this reason, the polarized light during black display selects the selection reflectivity in reflection horizon 1005 to improve, and the luminous efficiency of peak value briliancy improves.

In addition, the alignment direction of liquid crystal is even if parallelly with the direction of propagation also can obtain same effect.This is because there is not the cause of the phase differential of liquid crystal for the direction of propagation.

Figure 11 shows the alignment direction 1010 and the angle theta of the direction of propagation 1009 and the relation of peak value briliancy of liquid crystal.In addition, the peak value briliancy has been that 0 value of spending has been carried out normalization with θ.

θ is that 0 degree and 90 briliancy of peak value when spending will become and be maximum, becomes to be minimum when 45 spend.This is because for the oblique light that sees through liquid crystal layer, is under the situation of 45 degree at θ, is easy to take place phase differential most and changes, the cause that circulation light reduces.

[formation of liquid crystal indicator and operating principle]

Fig. 4 shows the displaying principle of the liquid crystal indicator of example 7 of the present invention.

Liquid crystal layer 1208 uses vertical alignment mode, selects polarized light reflection horizon A1201 and polarized light to select reflection horizon B1206 to be laminated to the both sides of liquid crystal layer 1208.At this moment, when medium tone shows, exist emergent light A1209 that once sees through liquid crystal layer and the emergent light B1210 that in polarized light selection reflection horizon up and down, reflects the back outgoing.This is because exist S ripple and P ripple owing to mixing in liquid crystal layer, selects with constant ratio light and catoptrical cause to take place to see through in the reflection horizon at polarized light.At this moment, the optical path length of emergent light B1210 in liquid crystal layer 1208 becomes for emergent light A1209 2 times.Therefore, emergent light A1209 has different phase differential with emergent light B1210.For this reason, the result just becomes and is emergent light A1209 and averaging of emergent light B1210 when watching, for the same principle of multi-region type liquid crystal panel, the effect of the briliancy grade that particularly can be reduced counter-rotating.
