130, cathode layer 140, light emitting functional layer 150 and cathode 141.Chromatic filter layer 120 and black matrix 130 are arranged in the first substrate
On substrate 110, the side of chromatic filter layer 120 and black matrix 130 far from the first underlay substrate 110 is arranged in cathode layer 140.Hair
Side of the cathode layer 140 far from chromatic filter layer 120 and black matrix 130 is arranged in light functional layer 150.Cathode layer 140 includes yin
Pole 141, cathode 141 fall into chromatic filter layer 120 on the first underlay substrate 110 in the orthographic projection on the first underlay substrate 110
Orthographic projection.Light emitting functional layer 150 contacts setting with cathode 141, and cathode 141 contacts setting with chromatic filter layer 120.
In the color membrane substrates that the embodiment of the present disclosure provides, since chromatic filter layer 120 and light emitting functional layer 150 are respectively provided with
On color membrane substrates, and light emitting functional layer 150 contacts setting with cathode 141, and cathode 141 is contacted with chromatic filter layer 120 and set
It sets.Therefore between light emitting functional layer 150 and chromatic filter layer 120 be not present gap, thus can avoid due to chromatic filter layer with
There are problems that certain interval between light emitting functional layer and the color offset phenomenon caused or brightness decay.It should be noted that when this
When the color membrane substrates that open embodiment provides are used for display panel, anode can be arranged in array substrate, and by by array
Substrate and color membrane substrates are to box so that anode is electrical connected with the light emitting functional layer contraposition overlap joint on color membrane substrates with realizing.
For example, the first underlay substrate 110 is transparent insulation substrate, for example, can be glass substrate or quartz base plate or its
The substrate for the material production that he is suitble to.
For example, chromatic filter layer 120 is separated multiple colored filters by black matrix 130, black matrix 130 may also function as pixel
The effect of restriction.
For example, in some instances, light emitting functional layer may include electroluminescence layer itself and be located at electroluminescence layer two

The contact setting of light emitting functional layer 150.As a result, using the color membrane substrates display panel in, conductive layer 160 can guarantee anode with
The Ohmic contact of light emitting functional layer.
For example, conductive layer 160 can be made by the way of vapor deposition, chemical vapor deposition (CVD) or transfer.
For example, in some instances, as depicted in figs. 1 and 2, black matrix 130 is in the side perpendicular to the first underlay substrate 110
Upward thickness is greater than thickness of the chromatic filter layer 120 on the direction perpendicular to the first underlay substrate 110.At this point, adjacent
Chromatic filter layer 120 between black matrix 130 can form the sunk structure recessed to the first underlay substrate 110.At this point, being recessed
The cathode and light emitting functional layer formed in structure also can accordingly be recessed to the first underlay substrate 110, so as to be easy to implement hair

It is aligned in the sunk structure.
Fig. 3 is the structural schematic diagram for another color membrane substrates that one embodiment of the disclosure provides, as shown in figure 3, black matrix
130 cross-sectional shape substantially inverted trapezoidal, the long bottom edge of the inverted trapezoidal are located at black matrix 130 far from the first underlay substrate 110
Side, also, thickness of the black matrix 130 on the direction perpendicular to the first underlay substrate 110 be greater than chromatic filter layer 120 exist
Perpendicular to the thickness on the direction of the first underlay substrate 110.It should be noted that being actually formed due to factors such as process conditions
Black matrix cross-sectional shape may and non-critical inverted trapezoidal, as long as to meet black matrix separate for the cross-sectional shape of black matrix
First underlay substrate on one side size be greater than black matrix close to the first underlay substrate while size.
It is and black when the cross-sectional shape of black matrix 130 is rough inverted trapezoidal in the color membrane substrates that this example provides
Thickness of the matrix 130 on the direction perpendicular to the first underlay substrate 110 is greater than chromatic filter layer 120 perpendicular to the first substrate
When thickness on the direction of substrate 110, when using the methods of vapor deposition production cathode layer 140, as shown in figure 3, due to black matrix
130 thickness are greater than chromatic filter layer 120, and the cross sectional shape with substantially inverted trapezoidal shown in Fig. 3, the cathode layer 140 of formation
It can disconnect at the edge of black matrix 130, to be naturally partitioned into two parts for mutually insulated, i.e., be connect with colored filter
The part of touching and the part contacted with black matrix.The part contacted with colored filter can be used as cathode, contact with black matrix
Part can be used as touch control electrode.
For example, as shown in figure 3, cathode layer 140 further includes touch control electrode 170 other than including cathode 141.Touch-control electricity
Pole 170 falls into orthographic projection of the black matrix 130 on the first underlay substrate 110 in the orthographic projection on the first underlay substrate 110.Cathode
141 with 170 mutually insulated of touch control electrode.When the cross-sectional shape substantially inverted trapezoidal of black matrix 130, cathode 141 and touch-control
Electrode 170 can be formed by same conductive layer.Also, since cathode layer can disconnect at the edge of black matrix automatically, cathode
Not needing additional masking process or Patternized technique with touch control electrode reduces cost so as to save technique.
For example, the cross-sectional shape of black matrix 130 is also possible to the other shapes such as hexagon, as long as can be realized cathode
140 partition of layer becomes the two-part purpose of mutually insulated.Therefore, the embodiment of the present invention is not to the cross of black matrix 130
Cross sectional shape is defined.
