Description
Technical field
The present invention relates to technical field of liquid crystal display, more particularly to a kind of liquid crystal display panel and preparation method thereof.
Background technology
In general, a polarising means is arranged in liquid crystal display upper surface, thus it is line that display, which is emitted to the light of intelligent's eye,
Polarisation.However, the photosensory cell of human eye gets used to natural light, the polarization direction of natural light be evenly distributed in all directions it is non-
Linearly polarized light, the stimulation to human eye photosensory cell are identical, but the received display of human eye on each polarization direction
Light be linearly polarized light, the photosensory cell of human eye only receives the luminous energy stimulation of a polarization direction, the stimulation obtained be it is non-
Weighing apparatus, observer is susceptible to the symptom with asthenopia when receiving linearly polarized light for a long time, therefore proposes rotatory polarization display meaning
Justice is great.
It is the structural schematic diagram of the common circularly polarized light display of current display as shown in Figure 1, includes first inclined successively
Photosphere 10, first substrate 20, liquid crystal layer 30,40 second polarizing layer 50 of second substrate and backlight 60, wherein in the first polarisation
The outside of layer 10 is provided with 1/4 λ wave plates 70 and surface-treated layer 80, by being provided with 1/4 λ wave plates in 10 outside of the first polarizing layer
70, can make outgoing linearly polarized light become circularly polarized light, however this circularly polarized light transformation and it is imperfect, because of 1/4 λ wave plates
The 70 phase delay delta nd=1/4 λ generated can only correspond to some wavelength, (centres of 380~780 wave bands typically 550nm
One wavelength), the light of 550nm and its neighbouring wavelength can preferably be changed into ideal circularly polarized light at this time, however separate
550nm (being less than or greater than 550nm) light of wavelength more cannot perfectly be changed into rotatory polarization, because for far from 550nm
(being less than or greater than 550nm), its phase delay delta of the light of wavelength nd was more than or less than 1/4 λ.
1/4 λ wave plate common used materials are illustrated in figure 2, the modified PC (modified polycarbonate) of signal are normalized in figure, PC (gathers
Carbonic ester), COC (cyclenes copolymer), TAC (Triafol T), COP (cycloolefine polymer), PMMA+LC (acrylic resins
Class+liquid crystal coating) made of 1/4 λ wave plates phase delay delta nd/ (Δ n589) d and wavelength relationship.Wherein there is modified PC materials
The material of the same (Y-axis increases with wavelength and the gradually increases) characteristic of material is referred to as inverse wave length dispersion, wherein having PMMA+LC materials
The material of the same (Y-axis is gradually reduced with the wavelength increase) characteristic of material is referred to as the long dispersion of downsea.Ideal 1/4 λ wave plate materials
Material is as shown in Fig. 2 cathetus, when for using such material same thickness, phase delay delta nd can with wavelength from 380~
780nm increases and increases, and makes the light of each wavelength that can occur the phase delay of 1/4 λ, however this material and is not present.
The wave plate using phase delay delta nd=1/4 λ, λ=550nm is illustrated as shown in Figure 4, for separate 550nm's
B, R light is changed into elliptically polarized light after penetrating 1/4 λ wave plates, it is assumed that the luminous intensity through RGB before sunglasses is R：G：B=1：
1：1, however the luminous intensity for penetrating sunglasses (on sunglasses with polarizing layer structure) RGB afterwards is R：G：B≠1：1：1, because
And color distortion as shown in Figure 3 is resulted in, and 1/4 λ wave plates setting made of positive wavelength and head sea long material is over the display
When, best observation angle under sunglasses is all different when chromaticity coordinates difference minimum () before and after penetrating sunglasses,
The observation angle is the axial angle with display upper polaroid axial direction of polarisation of sunglasses.
Based on above-mentioned actual conditions and theory it can be found that current rotatory polarization display has the following defects：
1) become elliptically polarized light far from the light for fixing some wavelength, be not the perfect circularly polarized light of comparison；
2) the 1/4 λ wave plates that different materials are made, the best observation angle under different sunglasses are different；
2) color change is very big when watching display picture by sunglasses.
