Liquid crystal layer 13 is located between first substrate 11 and second substrate 12, and between the first both alignment layers 161 and the second both alignment layers 162.Liquid crystal layer 13 has multiple liquid crystal molecule, and each liquid crystal molecule has a long axis direction.In this embodiment, liquid crystal layer 13 can be subject to the impact of the first both alignment layers 161 and the second both alignment layers 162 and arrange towards alignment direction.In an embodiment, the long axis direction of each liquid crystal molecule is the LCD alignment direction in orientation (Rubbing) processing procedure.
First Polarizer 14 is arranged at the first substrate 11 side away from second substrate 12, and the second Polarizer 15 is arranged at the second substrate 12 side away from first substrate 11.In the present embodiment, first Polarizer 14 such as can be connected to first substrate 11 in attaching mode (such as can pass through optical cement (opticalclearadhesive away from the lower surface of second substrate 12, or pressure-sensing glue (pressuresensitiveadhesive OCA), PSA) adhesion), and the second Polarizer 15 is also connected to the second substrate 12 upper surface away from first substrate 11 in attaching mode.Wherein, the thickness of the first Polarizer 14 or the second Polarizer 15 can between 5 microns (μm) to 50 micron；Preferably, the thickness of the first Polarizer 14 and the second Polarizer 15 can between 12 microns to 30 microns.
Second Polarizer 15 has one first compensation film 151 and one second and compensates film 152, and the first Polarizer 14 has one the 3rd compensation film 141.Wherein, the first material compensating film 151 or the second compensation film 152 or the 3rd compensation film 141 can be such as cyclic olefin monomers polymer (CycloOlefinPolymers, COP) or Merlon (Polycarbonate, PC) etc..In this, compensate film 151, second for first and compensate the material respectively COP of film 152 and the 3rd compensation film 141.Additionally, the first of the present embodiment compensates film 151 and is directly arranged on the second substrate 12 side away from first substrate 11, and second compensate film 152 be arranged on the first compensation film 151, and the 3rd compensates the blooming that film 141 is a zero-bit difference (or claiming zero optical path difference), and it is directly arranged on the first substrate 11 side away from second substrate 12.Additionally, the thickness of the first compensation film 151 and the second compensation film 152 and d1 compensate the thickness d 2 (d1 > d2) of film 141 more than the 3rd.In one embodiment, the first thickness and d1 compensating film 151 and the second compensation film 152 can be such as 60um, and the 3rd thickness d 2 compensating film 141 can be such as 40um.

In this, so-called " slow-axis direction " refers to, when light is by a certain element, the ray velocity that electric field vibrates along a direction (S axle) is slower, it is slow-axis direction (ray velocity that electric field vibrates is very fast, is quick shaft direction) along the direction (F axle) perpendicular with the direction.Therefore, when light is by compensating film, namely its slow direction can be described as the slow-axis direction of this compensation film.Wherein, light by the speed of a certain element and its refractive index (representing with n) about (n and the light velocity are inversely proportional to).In this, first compensates film 151 or second compensates film 152 and can have multiple axial refractive index, and this first slow-axis direction or this second slow-axis direction be those axially in, maximum one of refractive index is axial.In the present embodiment, the first compensation film 151 and the second compensation film 152 can be respectively provided with the refractive index of three axial (representing with x, y, z) (with Nx、Ny、NzRepresent), and in the first slow-axis direction and the second slow-axis direction respectively those axial x, y, z, refractive index maximum is axially.

Again by way of further example, in another embodiment, if first compensates the 3rd axial refractive index N of film 151zMore than its first axial refractive index Nx, and the first the first axial refractive index N compensating film 151xMore than its second axial refractive index Ny(i.e. Nz> Nx> Ny), then the first the first slow-axis direction compensating film 151 is the 3rd axial z of the first compensation film 151.If it addition, second compensates the first axial refractive index N of film 152xMore than its second axial refractive index Ny, second compensates the second axial refractive index N of film 152yThe refractive index N axial more than the 3rdz(i.e. Nx> Ny> Nz), then the second the second slow-axis direction compensating film 152 is the first axial x of the second compensation film 152, and the present invention does not limit.
In addition; first Polarizer 14 of the present embodiment has more one first light polarizing film 142 and one first protecting film 143; first light polarizing film 142 is arranged at the 3rd compensation film 141 side away from first substrate 11, and the first protecting film 143 is arranged at the first light polarizing film 142 away from the 3rd side compensating film 141.Additionally; second Polarizer 15 has more one second light polarizing film 153 and one second protecting film 154; second light polarizing film 153 is arranged on the second compensation film 152 side away from second substrate 12, and the second protecting film 154 is arranged at the second light polarizing film 153 away from the second side compensating film 152.Wherein, the material of the first light polarizing film 142 and the second light polarizing film 153 respectively unidirectional polar biased state material, and it is for example and without limitation to polyvinyl alcohol (polyvinylalcohol, PVA), and first the polarization angle of light polarizing film 142 and the second light polarizing film 153 orthogonal (such as the absorption axle of the first light polarizing film 142 is 90 degree, the absorption axle of the second light polarizing film 153 is 0 degree, or on the contrary).It addition, the material of the first protecting film 143 and the second protecting film 154 is for example and without limitation to triacetate fiber (TriacetylCellulose, TAC)).Owing to the material of the first light polarizing film 142 and the second light polarizing film 153 comprises hydrophilic polarized material; therefore; the first light polarizing film 142 can be protected by the first protecting film 143, the second light polarizing film 153 can be protected by the second protecting film 154, produce chemical change in order to avoid aqueous vapor invades and affect its function.
It addition, the display floater 1a of the present embodiment more can include a thin film transistor (TFT) array, a colour filter array and a black-matrix layer (figure does not all show).Wherein, thin film transistor (TFT) array, colour filter array and liquid crystal layer 13 can form a pel array.In the present embodiment, thin film transistor (TFT) array is formed on first substrate 11, first substrate 11 is made to become a thin film transistor base plate (TFT substrate), and black-matrix layer and colour filter array are respectively formed on second substrate 12, second substrate 12 is made to become a colored optical filtering substrates (CF substrate).But, in another embodiment, black-matrix layer or colour filter array also can be respectively formed in first substrate 11 so that it is become a BOA (BMonarray) substrate, or becoming a COA (colorfilteronarray) substrate, the present invention is not all any limitation as.Additionally, display floater 1a more can include plural number scanning line and complex data line (figure does not show), such scanning line and such data wire are crisscross arranged, and are such as mutually perpendicular to and define the region of this pel array.Therefore, when the light E that a backlight module (figure does not show) sends is sequentially through the first Polarizer 14, first substrate 11 (TFT substrate), the first both alignment layers 161, liquid crystal layer the 13, second both alignment layers 162, second substrate 12 (CF substrate) and the second Polarizer 15, can show that color forms image by each pixel of display floater 1a, to reduce big visual angle dark-state light leak and to improve color offset phenomenon, reach preferably compensation effect.
It addition, refer to shown in Figure 1B, it is the schematic diagram of display floater 1b that another of present pre-ferred embodiments implements aspect.
Primary difference is that with display floater 1a, the first substrate 11 of display floater 1a is TFT substrate, and second substrate 12 is CF substrate, but in display floater 1b, its first substrate 11 is CF substrate, and second substrate 12 is TFT substrate, and the light E that backlight module (figure does not show) sends is sequentially through the second Polarizer 15, second substrate 12 (TFT substrate), second both alignment layers 162, liquid crystal layer 13, first both alignment layers 161, when first substrate 11 (CF substrate) and the first Polarizer 14, can show that color forms image by each pixel of display floater 1b.
Additionally, the other technologies feature of display floater 1b can refer to the similar elements of display floater 1a, repeat no more.
Additionally, please respectively refer to shown in Fig. 2 A and Fig. 2 B, wherein, Fig. 2 A is the phase angle variations schematic diagram that the display floater of known technology represents with Peng Karui (Poincar é) ball, and the phase angle variations schematic diagram that the display floater 1a that Fig. 2 B is the present invention represents with Peng Karui ball.In this, the display floater of known technology equally has the element (first substrate, second substrate, liquid crystal layer, the first Polarizer and the second Polarizer) of display floater 1a, but, it is known that the characteristic that the first of the second Polarizer of display floater compensates film and the second compensation film is different with the embodiment of display floater 1a.
In time ideally watching display floater, when utilizing the compensation film of liquid crystal molecule and Polarizer to reach light by display floater, its polarization direction going out light is orthogonal with the polarization direction entering light, even if also some P2 and some P1 is on axle S1.
nullIn the track of Fig. 2 A，The light that the backlight module of known display floater sends，The first light polarizing film can be first passed through and form the polarization light with phase place，That is on axle, put P2 position，Then via liquid crystal layer can offer curves C1 phase difference track compensate，Its first compensate film can offer curves C2 phase difference track compensate，Its second compensate film can offer curves C3 phase difference track compensate，Make at the polarization light with phase place before the second light polarizing film in the position of a P3，Due to a P3 and it is desirable that still have a spacing (phase contrast) through the some P1 of the polarization light with phase place of the second light polarizing film，Wherein first compensate film and compensate film purpose with second and compensating the big visual angle light leak and color offset phenomenon that cause through phase contrast produced by liquid crystal layer because of light，But it still has very big phase contrast by the first light polarizing film formation with some P1 position on the axle of the polarization light of phase place due to the light phase difference after compensating and expectation，Therefore effect is still undesirable.
Similarly, in Fig. 2 B, the liquid crystal layer 13 of display floater 1a can offer curves C1 phase difference track compensate, the second Polarizer 15 first compensate film 151 can offer curves C2 phase difference track compensate, and the second of the second Polarizer 15 compensate film 152 can offer curves C3 phase difference track compensate.Comparison diagram 2A and Fig. 2 B can find, compared to Fig. 2 A, Fig. 2 B compensates film 151, second through liquid crystal layer 13, first and compensates the polarization light with phase place of film 152 in the position of a P4, its compared to the some P3 position in known Fig. 2 A structure closer to a P1, that is its track is relatively close to the absorption shaft position of Polarizer, therefore that light leak and color offset phenomenon can be more known is less.
It addition, please respectively refer to shown in Fig. 3 A and Fig. 3 B, wherein, Fig. 3 A is full visual angle dark-state light leak schematic diagram (Cono figure) of the display floater of known technology, and the full visual angle dark-state light leak schematic diagram of the display floater 1a that Fig. 3 B is the present invention.

It addition, please respectively refer to shown in Fig. 4 A and Fig. 4 B, wherein, Fig. 4 A is full viewing angle contrast's schematic diagram of the display floater of known technology, and full viewing angle contrast's schematic diagram of the display floater 1a that Fig. 4 B is the present invention.
Comparison diagram 4A and Fig. 4 B it is also seen that, compared to known technology, full viewing angle contrast's property of the display floater 1a of Fig. 4 B is more known uniformly.
It addition, please respectively refer to shown in Fig. 5, wherein, Fig. 5 is the display floater full visual angle color point distribution schematic diagram with the display floater 1a of the present invention of known technology.
Can being found by Fig. 5, compared to known technology, the full visual angle color point distribution of display floater 1a is comparatively concentrated, and the dark-state light leak at its full visual angle is also less.
In sum, because of in the display floater of the present invention, first both alignment layers and the second both alignment layers have identical alignment direction, and the first Polarizer is arranged at the first substrate side away from second substrate, and the second Polarizer is arranged at the second substrate side away from first substrate.It addition, the second slow-axis direction of the first of the second Polarizer the first slow-axis direction and the second compensation film compensating film is substantially respectively perpendicular the alignment direction of the first both alignment layers and the second both alignment layers.Thereby, compared to known technology, the display floater of the present invention can more reduce big visual angle dark-state light leak and improve color offset phenomenon, to reach preferably compensation effect.
