Specific embodiment
The explanation of following embodiment is to can be used to the particular implementation of implementation to illustrate this announcement with reference to additional schema
Example.
Referring to Fig. 1, Fig. 1 shows the colored filter substrate 1 according to one embodiment of this announcement.
The colored filter substrate 1 includes a substrate 10, a color blocking layer 12 and a black matrix" 14.
The color blocking layer 12 is set on the substrate 10 and including multiple color blockings 120.The multiple color blocking 120 is in matrix
It arranges and corresponding with multiple picture elements of array basal plate (not shown) or sub- picture element.
The multiple color blocking 120 can be, but not limited to as red color resistance, green color blocking, blue color blocking or white color blocking.
The black matrix" 14 is set on the substrate 10 and including multiple strip structure 140,142.It is two adjacent
A strip structure 140 or 142 is provided between color blocking 120.In addition, the black matrix" 14 further comprises two strip knots
Structure 144 is respectively arranged at two opposed edge sections of the substrate 10.It is noted that described two strip structures 144 can root
It is arranged or is not provided with according to needs.
The multiple strip structure 140,142,144 extends to the one of the substrate 10 by one first side of the substrate 10
Second side (along the vertical direction of Fig. 1).First side is opposite with described second side.
It is described in the colored filter substrate 1 of this announcement in order to solve the problems, such as not improving aperture opening ratio in the prior art
At least one of multiple strip structures 140 and 144 includes an at least protrusion 146.An at least protrusion 146 is from described more
A strip structure 140 and 144 outwardly protrudes extension.
More particularly, an at least protrusion 146 along the multiple strip structure 140 and 144 short side direction
(i.e. width) is protruded to the both sides of the multiple strip structure 140 and 144 to be extended.In this present embodiment, at least one protrusion
Portion 146 is different from the length that an at least protrusion 146 extends to another side protrusion to the length that one side protrusion extends.Or
Person, an at least protrusion 146 can be convex to another side with an at least protrusion 146 to the length that one side protrusion extends
The equal length extended out.
At least position of a protrusion 146 is corresponding with the position of a photoresist spacer 16.More particularly, described
Photoresist spacer 16 is set on an at least protrusion 146.In in the prior art, since the photoresist spacer 16 has
Certain size, in order to enable a strip structure to cover the photoresist spacer 16 completely, the strip structure needs have
Certain width and aperture opening ratio can not be improved.In the colored filter substrate 1 of this announcement, due to an at least protrusion 146
The photoresist spacer 16 can be covered completely, therefore there is the strip structure 140,144 of an at least protrusion 146
Width needs not be under the size limitation of an at least protrusion 146.That is, having an at least protrusion 146
The width of the strip structure 140,144 can be less than the width without at least strip structure 142 of a protrusion 146
Degree.Due to having the width of the strip structure 140,144 of an at least protrusion 146 that can reduce, the institute of this announcement
The area for stating black matrix" 14 can reduce, therefore aperture opening ratio can be improved.
It is noted that in the embodiment of Fig. 1, the protrusion 146 from the multiple strip structure 140 and 144 to
Outer protrusion extends.In another embodiment, the protrusion 146 can outwardly protrude extension from the strip structure 142.
It is noted that the protrusion 146 is set to the strip structure 140 and 144 in the embodiment of Fig. 1
Both ends, however this announcement is not limited to this.The position of the protrusion 146 can be fitted according to the position of the photoresist spacer 16
Work as design.The photoresist spacer 16 is well known for ordinary skill in the art, and does not add to repeat in this.
Referring to Fig. 2, Fig. 2 shows the colored filter substrate 2 according to another embodiment of this announcement.
The colored filter substrate 2 includes a substrate 20, a color blocking layer 22 and a black matrix" 24.
The color blocking layer 22 is set on the substrate 20 and including multiple color blockings 220.The multiple color blocking 220 is in matrix
It arranges and corresponding with multiple picture elements of array basal plate (not shown) or sub- picture element.
The multiple color blocking 220 can be, but not limited to as red color resistance, green color blocking, blue color blocking or white color blocking.
The black matrix" 24 is set on the substrate 20 and (shows a frame in Fig. 2 including multiple frame-shaped constructions 240
Shape structure 240).A frame-shaped construction 240 is provided between two adjacent color blockings 220.
The multiple frame-shaped construction 240 is generally in rectangle.In order to solve that asking for aperture opening ratio can not be improved in the prior art
It inscribes, in the colored filter substrate 2 of this announcement, at least one four angles of the multiple frame-shaped construction 240 respectively include one
Protrusion 242.The protrusion 242 outwardly protrudes extension from the corresponding angle of the multiple frame-shaped construction 240.More particularly,
The protrusion 242 outwardly protrudes extension along the diagonal line of the frame-shaped construction 240.The size of the protrusion 242 can root
It is appropriately designed according to needing to make.
In the embodiment of Fig. 2, four of the multiple frame-shaped construction 240 can be made by the way that the protrusion 242 is arranged
Angle has the rectangular shaped of protrusion.In the prior art, four angles of a frame-shaped construction are implemented as fillet, and being implemented as fillet can make
Increase at the area of frame-shaped construction.Although this announcement is arranged the protrusion 242, the black matrix" 24 is described in the setting
Four angles that area after protrusion 242 can be less than black matrix" in the prior art are implemented as the area of fillet.It is more clear
Say that the area of the black matrix" 24 of this announcement can reduce, therefore aperture opening ratio can be improved in ground.
It is noted that the protrusion 242 is for having the multiple frame-shaped construction 240 in the embodiment of Fig. 2
Black matrix" 24.In another embodiment, black matrix" that the protrusion 242 can be used for having multiple wedge structures.
From the embodiment of Fig. 1 and Fig. 2 it is found that the colored filter substrate of this announcement include a substrate, a color blocking layer and
One black matrix".The color blocking layer is set on the substrate and including multiple color blockings.The black matrix" is set to the base
