Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein
Described embodiment is merely to illustrate and explained the utility model, is not limited to the utility model.
Fig. 1 shows the schematic diagram for the black matrix structure that the embodiment of the utility model one provides.As shown in figure 1, this reality
A kind of black matrix structure is provided with a new embodiment, the black matrix structure can include substrate 100 and be formed described
One or more black matrix"s 401 on substrate 100, wherein each black in one or more of black matrix"s 401
The surface that matrix 401 is in contact with the substrate 100 is the surface of out-of-flatness, and the surface of the out-of-flatness can cause light to enter
When being incident upon the contact surface of black matrix" 401 and substrate, diffusing reflection occurs.So as to form display surface by the black matrix structure
During plate, in black matrix area diffusing reflection occurs for the reflected light that display panel is incident to from front, improves display panel and shows
The contrast of the picture shown.
Alternatively, black matrix" 401 can be with the arrangement in cycle on the substrate 100.
With further reference to Fig. 1, in one embodiment, each black matrix" 401 can with the surface that substrate 100 is in contact
To be raised.In this embodiment, in order that be formed on the substrate 100 black matrix" 401 with the substrate
100 surfaces being in contact are raised, corresponding on the substrate 100 one or more grooves can be formed, at this or more
The region of each groove in individual groove carries out light blockage coating and is obtained with black matrix" 401, and the black matrix" can make
Diffusing reflection occurs for the light that must be incident on the contact surface of black matrix" and substrate.
Wherein it is possible to the black matrix" forming region on substrate 100 is carried out using the chemical liquid of hydrofluoric acid etc.
To form the groove, the contents of the section will hereinafter describe in detail etching.
Alternatively, substrate 100 can be glass substrate, but the utility model embodiment is not restricted to this.
The black matrix structure that black matrix structure of the prior art and the utility model embodiment will hereafter be provided
It is compared explanation.
Fig. 2 shows that the schematic diagram of mirror-reflection occurs for black matrix structure of the prior art, and Fig. 3 shows this practicality
Irreflexive schematic diagram occurs for the black matrix structure that new embodiment provides.Used in Fig. 2 and Fig. 3 illustrated embodiment
Substrate be glass basic 101.
As shown in Fig. 2 in black matrix structure of the prior art, the contact surface of black matrix" 403 and glass substrate 101
It is smooth.For display panel comprising the black matrix structure after assembling, extraneous light can be from the side of glass substrate 101
Inject.The color layer formed on glass substrate 101 is formed by the photoresist with certain transmitance, therefore, is injected
Reflected light of the extraneous light in color layer region it is very weak.Because the material for making black matrix" 403 is that have extremely low transmitance
Photoresist, therefore it is anti-on smooth contact surface of the black matrix" 403 with glass substrate 101 more minute surface to occur
Penetrate, will greatly reduce visual experience when the reflection light of mirror-reflection enters human eye, influence the contrast of display picture.
As shown in figure 3, Fig. 3 is the partial enlarged drawing of black matrix" 401 shown in Fig. 1, for showing the utility model
There is provided in embodiment with glass substrate 101 have out-of-flatness contact surface black matrix" 401 structure to picture display effect
Lifting.Equally when extraneous light incides the base surface of black matrix" and glass substrate, because black matrix" 401 makes
On groove, it can make incident ray that diffusing reflection occur, such as because of the concaveconvex structure that glass etching is formed in itself plus groove
This, reflected light will not concentrate injection human eye in one direction, thus can substantially increase the contrast of display picture, simultaneously
Lift display effect.
Fig. 4 shows the partial schematic diagram of the structure for the colored filter that the embodiment of the utility model one provides.Such as Fig. 4 institutes
Show, the utility model embodiment also provides a kind of colored filter, and the colored filter can include：Above-mentioned black matrix" knot
Structure；And color layer, the color layer are formed in the same side of the substrate 100 with one or more of black matrix"s 401, and
And the color layer is formed at the non-black matrix area on the substrate 100.The color layer can include：Red pixel
The color layer 303 of the color layer 301 of composition, the color layer 302 of green pixel composition and blue pixel composition.
Alternatively, the color layer can be made up of the photoresist with certain transmitance, to cause extraneous light to exist
Color layer region produces weaker reflected light.
Further, colored filter can also include protective layer, ITO conducting films etc..It is real by using the utility model
The black matrix structure of example offer is provided.
