It is the film layer schematic diagram of display device plate in the prior art with reference to Fig. 1, Fig. 1.Display device 00 in Fig. 1, including phase
To the cover board 011 and display panel 012 of setting；
Display panel 012 includes that the color membrane substrates 013 being oppositely arranged and array substrate 014, color membrane substrates 013 are located at array
Substrate 014 is close to 011 side of cover board；
It further include collimating aperture 015, collimating aperture 015 runs through color membrane substrates 013 in the direction perpendicular to array substrate 014
With the part film layer of array substrate 014；
Color membrane substrates include the first glass substrate 01, the first light blocking layer 02, the first planarization layer 03, the second light blocking layer 04 with
And second planarization layer 05；
First light blocking layer 02 is located at the first glass substrate 01 close to the side of array substrate 014, and the first light blocking layer 02 wraps
Include multiple first opening portions 021；
First planarization layer 03 is located at the first light blocking layer 02 close to 014 side of array substrate；
Second light blocking layer 04 is located at the first planarization layer 03 close to the side of array substrate 014, and the first light blocking layer 04 wraps
Include multiple first opening portions 041；
Second planarization layer 05 is located at the second light blocking layer 04 close to 014 side of array substrate；
Liquid crystal layer 06 is folded between color membrane substrates 013 and array substrate 014；
Array substrate 014 includes multiple fingerprint identification units 010, the second glass substrate 09, third light blocking layer 07 and the
Three planarization layers；
Fingerprint identification unit 010 is located at array substrate 014 close to 013 side of color membrane substrates；
Third planarization layer 08 is located at fingerprint identification unit 010 close to 013 side of color membrane substrates；
Third light blocking layer 07 is located at third planarization layer 08 close to 013 side of color membrane substrates, and third light blocking layer 07 includes

Where perpendicular to the second glass substrate on the direction of plane, the first opening portion 021, the second opening portion 041, third
Opening portion 071, collimating aperture 015, fingerprint identification unit 010 overlap mutually.
It is understood that including collimating aperture 015, the work of fingerprint identification unit 010 in display device in the prior art
Make principle are as follows: when finger contacts display screen, reflect when light source is irradiated on the valley line and crestal line of finger print, due to paddy
The reflection angle of line and crestal line and the intensity of illumination reflected back are different, and by light projection to fingerprint identification unit 010, fingerprint is known
The inductive signal received is transmitted to fingerprint recognition signal receiving unit by fingerprint signal line and (not shown in figure by other unit 010
Out), so that fingerprint recognition signal receiving unit goes out the valley line and crestal line of fingerprint according to the signal identification received.When finger contacts
When to glass cover-plate 011, a series of fingerprint ridge Q and fingerprint valley P on the skin surface of finger end form fingerprint, and light passes through liquid crystal layer
003, finger is reached after color membrane substrates 001, upper polaroid (not shown) and glass cover-plate 011, by reflection using standard
Straight hole 015 reaches the fingerprint identification unit 010 in array substrate 014.When making display panel, in order to not influence display panel
Usually color blocking is arranged in open region for display, and fingerprint identification unit 010 is arranged in the non-open region of display panel, due to
The position of non-open region is limited, therefore limits collimating aperture size, secures collimating aperture on the direction for being parallel to color membrane substrates
Maximum spacing, i.e. the width d of collimating aperture, due to 01 He of the first glass substrate being folded in light shield layer in color membrane substrates 013
Between fingerprint identification unit 010 in array substrate 014, the height of collimating aperture 015 is again limited, since the width of collimating aperture is solid
It is fixed, the size of fingerprint identification region T area, fingerprint are controlled in range that can only be restricted by the height of control collimating aperture 015
Because the bigger control fingerprint identification region T area of the height of 010 collimating aperture 015 of fingerprint identification unit is smaller, due to fingerprint recognition
Region T area is excessive, causes to include multiple fingerprint ridge Q and multiple fingerprint valley P, as shown in Figure 1,015 insufficient height of collimating aperture, leads
It causes fingerprint identification region T area excessive, including two fingerprint ridge Q and two fingerprint valley P, can not identify and specifically refer to wrinkle ridge Q also
The problem of being fingerprint valley P, reducing detection sensitivity.Finger print information identification region is received in order to solve above-mentioned fingerprint identification unit
It is excessive, reduce detection sensitivity the problem of.The prior art by forming the first frequency modulated light layer 012 on the first glass substrate 01, then
The first planarization layer 03 that a layer thickness is greater than 9 μm is formed on the first frequency modulated light layer 012, although increasing collimating aperture 015
It highly, but is difficult to realize for forming first planarization layer 03 of a layer thickness greater than 9 μm: since planarization layer can not
The primary planarization layer for forming thickness and being greater than 9 μm, needing to carry out repeatedly to form a film leads to manufacturing process low efficiency, simultaneously because flat
Change layer thickness it is excessively high can easily cause substrate shrink, display brightness it is uneven, and display is caused various traces occur
Phenomenon.Thickness insoluble problem can all occur greater than 9 μm of planarization layer, thus by the thickness that increases planarization layer come
It is restricted for increasing the height of collimating aperture, therefore the above method still will appear fingerprint identification unit and receive finger print information cog region
The problem of domain is excessive, reduces detection sensitivity.In order to solve the above-mentioned technical problem, the invention proposes a kind of display devices.It closes
