As shown in Figure 1, structure of polarized light includes the successively folded phase compensation film 100 set, light polarizing film 200, optical compensation films
300, wherein phase compensation film 100 includes incidence surface 100A and light-emitting surface 100B, and incidence surface is the one side for receiving incident light, light
Line enters after the progress phase compensation of phase compensation film 100 from the plane of incidence to be projected from light-emitting surface, since light can go out after liquid crystal
The phenomenon that existing phase delay, by phase compensation film, light phase can be modified.In one embodiment, phase compensation
Film can be the combination of A- plate or C- plate or A- plate and C- plate.Light by phase compensation enters light polarizing film 200, light polarizing film 200
For carrying out polarization manipulation to light to form linearly polarized photon, only the direction of an electric field light parallel with the penetrating shaft of light polarizing film
Light polarizing film can be penetrated, i.e., the direction of an electric field of the light projected from light polarizing film 200 is parallel with the penetrating shaft of light polarizing film.Light polarizing film 200
It can be polyvinyl alcohol film, polyvinyl alcohol film with high transparency, high ductibility energy and has polarization to light.Optical compensation
Film 300 is stacked at the top layer of structure of polarized light, and what is contacted with air is formed with multiple grooves 301 on one side, and optical compensation films have
First refractive index, the first refractive index are greater than air refraction, are from light when light, which penetrates optical compensation films 300, enters air
Compact substance enters the process of light thinning medium.Simultaneously as the width of groove 301 is less than or close to wavelength, which is equivalent to a grating,
In the groove diffraction can occur for light.In a display device, since most light are vertical incidence into polarizer, i.e.,
Most light are perpendicular to incidence surface, and this programme is by being arranged optical compensation films in top layer and connecing in optical compensation films and air
The one side of touching forms groove, which forms grating, and the first refractive index of optical compensation films is greater than air refraction, incident light
When penetrating optical compensation films, diffraction can occur in groove, change the propagation path of vertical incidence light, light is made to deflect,
To make positive visual angle light type energy be assigned to big visual angle, the image quality at side view angle is improved.
As shown in connection with fig. 2, the width of groove is X, and the value range of X can be 300nm≤X≤1000nm, when light is vertical
When penetrating the entrance air of optical compensation films 300, diffraction occurs at groove 301, i.e. light propagation path changes, and light is inclined
It from original normally incident direction, is dissipated to side, therefore has more light and inject side, improve the image quality of side view angle.
It should be understood that first refractive index n1 and the difference of air refraction n2 are bigger, diffraction phenomena is more obvious, easier to face light
Type energy is assigned to big visual angle.In one embodiment, the value range of first refractive index n1 is 1.0 < n1 < 2.5, air refraction

Close to the wavelength of incident light.Due in a display device, the light that backlight module generates is largely to concentrate vertical incidence to aobvious
Show panel, if the surfacing of each tunic and being mutually perpendicular to vertical incidence light in structure of polarized light, vertical incidence light penetrates polarisation
It will not change its direction of propagation when plate, when light vertical incidence, is still vertically projected, and cause light to concentrate on positive angle, so that
The display image quality of positive apparent direction is preferable, and side view angle is since light is weaker, and the image quality of side view angle is poor.In the present solution,
Multiple grooves 301 are formed with due to being provided on optical compensation films and optical compensation films in top layer, groove 301 can make vertically to enter
It penetrates light and generates diffraction, light deviates original normally incident direction, dissipates to side, therefore have more light and inject side
The image quality of side view angle is improved on side.When groove is strip-shaped groove and is arranged side by side, only occur in one-dimensional square (X-direction)
Diffraction makes divergence of beam to the two sides of groove；When groove is arranged in two-dimensional rectangle array, since the length and width of groove is equal
Be less than or close to incident light wavelength, diffraction can occur in the two-dimensional surface (X-direction and Y-direction).In some embodiments, recessed
Slot 301 is cuboid groove, and in other examples, groove 301 can also be the groove of other forms, and the size of groove can make
Diffraction occurs for incident light.In one embodiment, the center spacing of adjacent grooves is less than or equal to 10 μm, i.e., less than one

The vertical all directions of optical axis, i.e. the photoelectricity field direction of the normal refraction of disc-like liquid crystal can be each side parallel with incidence surface
To corresponding normal refractive index is n1o, in the present embodiment, first refractive index is C- compensation film normal refractive index n1o.Light warp
Become linearly polarized light after crossing the polarization manipulation of light polarizing film, the direction of an electric field of the linearly polarized light is parallel with penetrating shaft, i.e. the linear polarization
The direction of an electric field of light and the optical axis of optical compensation films are vertical, therefore normal refraction, first refractive only occur in optical compensation films
The normal refractive index n1 of rate selection optical compensation filmso, n1oGreater than air refraction n2.
In another embodiment, optical compensation films 300 are uniaxial A- compensation film, can be filled in uniaxial A- compensation film to
Column phase liquid crystal, the optical axis of nematic liquid crystal are parallel to incidence surface and are parallel to the penetrating shaft of light polarizing film, the abnormality of nematic liquid crystal
Refractive direction be photoelectricity field direction it is parallel with nematic liquid crystal optical axis, i.e., the photoelectricity field direction of the abnormal refraction of nematic liquid crystal and
The penetrating shaft of light polarizing film is parallel, and corresponding abnormal refraction rate is n1e, in the present embodiment, first refractive index is that A- compensation film is anti-
Normal refractive index n1e.Light becomes linearly polarized light after the polarization manipulation of light polarizing film, the direction of an electric field of the linearly polarized light with penetrate
Axis is parallel, i.e. the direction of an electric field of the linearly polarized light and the optical axis of optical compensation films is parallel, therefore only occurs in optical compensation films
Abnormal refraction, first refractive index choose the abnormal refraction rate n1 of optical compensation filmse, n1eGreater than air refraction n2.
