As shown in Figure 1, Figure 2, the utility model embodiment provides a kind of liquid crystal display device, including it is laminated from the bottom up
The liquid crystal display die set 100 and touch-screen 200 of setting, the lower surface of the touch-screen 200 are stacked gradually equipped with line from top to bottom
Light polarizing film 300 and onlap flexion film 400, the penetrating shaft of the polarizing axis for onlapping flexion film 400 and line polarisation film 300 it
Between angle be 45 °, flexion film 400 and the line polarisation film 300 of onlapping is arranged on liquid crystal display die set 100 and touch-screen 200
Between can make liquid crystal display device seem when not showing one black, no color differnece.Wherein, flexion film 400 is onlapped（SRF）For
Retardation film with larger retardation, can be converted into circularly polarized light by linearly polarized light.Liquid crystal described in the utility model
Show that module 100 includes backlight module 110 and the liquid crystal panel module 120 being arranged on backlight module 110, the backlight module
110 for liquid crystal display die set 100 to provide backlight, and the liquid crystal panel module 120 generally comprises from the bottom up layer successively
Folded the first polaroid 121 set, array base palte 122, liquid crystal 123,124 and second polaroid 125 of color membrane substrates, the liquid crystal
Panel module 120 to for liquid crystal display die set 100 provide image display.Further, the liquid crystal display die set 100 is with touching
Touch and pasted between shielding 200 by 500 frame of adhesive, its center patch is four by the surrounding of liquid crystal display die set 100 and touch-screen 200
Week pastes.Further, the adhesive 500 is solid state optics glue or liquid optical cement or two liquid mixed hardening glue.
Since the setting of the first polaroid 121 and the second polaroid 125 in liquid crystal panel module 120 can make whole liquid crystal
The brightness of display module 1 declines, therefore as a further improvement, between the backlight module 110 and liquid crystal panel module 120 also
Equipped with the brightness enhancement film 111 made of APF materials, the setting of the brightness enhancement film 111 can improve the brightness of liquid crystal display die set 1
30%-35%.Wherein, APF materials are the reinforcing materials using aluminized polyester film as surface, coated with the rubber asphalt containing coagent
Adhesive material.Further, the brightness enhancement film 111 is bonded by PSA glue with the first polaroid 121, and the brightness enhancement film 111 is worn
The absorption axiss of saturating axis and the first polaroid 121 are perpendicular.Wherein described brightness enhancement film 111 is pasted by PSA glue and the first polaroid 121
Composition and division in a proportion brightness enhancement film 111 is bonded with backlight module 110 to be easier to be bonded, more precisely.
As shown in Figure 1, when liquid crystal display die set 100 does not shine, light source passes through institute from extraneous natural light, natural light
The linearly polarized light perpendicular to absorption axiss is will convert into after stating line polarisation film 300, when the polarizing axis and line that onlap flexion film 400 are inclined
When angle is 45 ° between the penetrating shaft of light film 300, linearly polarized light becomes circularly polarized light after onlapping flexion film 400, and circle is inclined
Light incidence liquid crystal display die set of shaking inverts behind 100 surface, and the circularly polarized light reflection after inverting is thin by onlapping flexion
The linearly polarized light become again after film 400 has just turned 90 ° with the linearly polarized light after incident inlet wire light polarizing film 300, with line polarisation film 300
Absorption axiss it is parallel and sponged by line polarisation film 300 so that making the natural light of extraneous incidence can not reflect, reach liquid crystal
Display module 100 reduces the purpose of the screen intensity of display device in the case of not shining, and screen is seemed that one is black, colourless
Difference.Since the retardation for onlapping flexion film 400 is larger（Re=8400nm/10500nm）, it is seen that all band light of light all may be used
With by making liquid crystal display device go back no color differnece in addition to reducing reflectivity and seeming enough black when not showing, realizing one
The black effect of body.
Pass through the reflectivity and aberration of three prescription cases of test in the utility model（Test equipment is CM-3600D）With contrast
The beneficial effect of scheme provided by the utility model, wherein scheme one are liquid crystal display die set in common liquid crystal display device with touching
Touch and be directly connected between shielding, scheme two is that rotatory polarization piece is instead pasted between liquid crystal display die set and touch-screen, and scheme three is this reality
With patch onlaps flexion film 400 and line polarisation film 300 between liquid crystal display die set 100 and touch-screen 200 in new, draw as
Lower data：
It was found from above-mentioned data, being pasted between liquid crystal display die set 100 and touch-screen 200 for the utility model use is onlapped
Flexion film 400 can make liquid crystal display device in the case where not showing closer to black with line polarisation film 300.
In the utility model when between the liquid crystal display die set 100 and touch-screen 200 being frame patch, because onlapping flexion
There are air layer between film 400 and liquid crystal display die set 100, the refractive index of air layer and the refractive index of SRF films are larger,
Flexion is being onlapped by the circularly polarized light that liquid crystal display die set 100 reflects in the case that liquid crystal display die set 100 is not shown
The reflection that reflectivity is 5% can occur for the lower surface of film 400 and then generation Circulated reflection can influence liquid crystal display die set 100
Overall reflectivity.Therefore, as a further improvement, the lower surface for onlapping flexion film 400 be additionally provided with antireflective film 600 to
Reduce the reflectivity for the lower surface for onlapping flexion film 400.Further, the thickness of the antireflective film 600 is less than or equal to 30 μ
m。
In the utility model when not pasted between the liquid crystal display die set 100 and touch-screen 200 for frame, then it can be not required
Increase antireflective film, and complete be bonded of flexion film and the second polaroid 125 will be onlapped by optical cement and realize liquid crystal display mode
Group 100 is bonded with touch-screen 200.
As a further improvement, the upper surface of the touch-screen 200 is additionally provided with moth eye film 700, between air and eyes
It is left that 5% can also occur to reduce reflectivity, when entering to inject touch-screen 200 due to natural light for the effective refractive index of the gradual change of formation
Right reflection, 0.3% can be dropped to by adding the reflectivity of 200 upper surface of touch-screen after moth eye film 700.Further, the moth
The thickness of eye mask 700 is less than or equal to 30 μm.
It is last it should be noted that above example only to illustrate the technical solution of the embodiment of the present invention rather than to its into
Row limitation, although the embodiment of the present invention is described in detail with reference to preferred embodiment, those of ordinary skill in the art
It should be understood that still can be to the technical solution technical scheme is modified or replaced equivalently of the embodiment of the present invention, and these are changed or wait
The scope of amended technical solution disengaging technical solution of the embodiment of the present invention cannot also be made with replacement.
