Aiming at the phenomenon that the color resistance and the substrate are peeled off in the area close to the corner in the display screen provided by the prior art, the inventor researches the display screen provided by the prior art as follows:
fig. 1 is a schematic view of a partial structure of a color filter substrate according to the prior art. Referring to fig. 1, the color filter substrate includes a substrate 1 and a plurality of color resistors 2 located on the substrate 1, a black matrix 3 is disposed between adjacent color resistors 2, and the black matrix 3 is located between the color resistors 2 and the substrate 1.
In the display panel provided by the prior art, the black matrix cannot be arranged on the side of the color resistor 2 departing from the substrate, because the material properties of the black matrix 3 and the color resistor 2 determine that when the black matrix 3 covers the color resistor 2, the black matrix 3 is easy to peel off from the color resistor 2, thereby reducing the reliability of the display panel.
In order to reduce the pixel aperture ratio of a partial region of the display panel, in the display panel provided in the prior art, the area of the black matrix 3 in the corresponding region of the color filter substrate is increased, so that the light transmission region of the color resistor 2 is reduced. This structure will reduce the contact area between the color resistor 2 and the substrate 1, and increase the risk of peeling the color resistor 2 from the substrate 1 in the color filter substrate.
In view of the above, the present invention provides a color film substrate, a display panel and a display device to solve the problems of color resistance and substrate peeling in a region close to a corner in the prior art. Embodiments of the color filter substrate, the display panel and the display device provided by the embodiments of the invention will be described in detail below.
Fig. 2 is a schematic structural diagram of a color filter substrate provided in the present invention, fig. 3 is a schematic structural diagram of a part of the color filter substrate shown in fig. 2, fig. 4 is a schematic structural diagram of a cross section of the color filter substrate shown in fig. 3, and referring to fig. 2 to fig. 4, the present embodiment provides a color filter substrate, including: a substrate 10;
a display area AA comprising a shaped boundary a1, a body area AA1, and an edge transition area AA2 located between the body area AA1 and the shaped boundary a 1;
the display area AA comprises a color resistor 20, the color resistor 20 is located on one side of the substrate 10, and the color resistor 20 at least comprises a first color resistor 21, a second color resistor 22 and a third color resistor 23;
the edge transition area AA2 includes a first blue color resist 30, the first blue color resist 30 being located on the side of the color resist 20 away from the substrate 10;
the first blue color resist 30 is a grid-like structure including a plurality of mesh openings 31, and a partial area of the color resist 20 located at the edge transition area AA2 is exposed through the mesh openings 31.
Specifically, with reference to fig. 2 to fig. 4, the color filter substrate provided in this embodiment includes a display area AA, where the display area AA includes at least one special-shaped boundary a1, and the special-shaped boundary a1 may be a curved segment, an arc segment, or an oblique segment, and in fig. 2 and fig. 3, only the special-shaped boundary a1 is taken as an example for description, optionally, the display area AA may further include two or more special-shaped boundaries a1, which is not limited in this embodiment.
The display area AA includes a color resistor 20, the color resistor 20 at least includes a first color resistor 21, a second color resistor 22 and a third color resistor 23, the arrangement of the first color resistor 21, the second color resistor 22 and the third color resistor 23 is various, fig. 3 exemplarily shows that the first color resistor 21, the second color resistor 22 and the third color resistor 23 are alternately arranged along the first direction X, in order to prevent color mixing among the first color resistor 21, the second color resistor 22 and the third color resistor 23, the edge of the color resistor 20 is subjected to light shielding, and in the edge transition area AA2, the edge of the color resistor 20 is covered by the first blue color resistor 30, so that the edge of the color resistor 20 is subjected to light shielding.
The display area AA comprises a main body area AA1 and an edge transition area AA2, the edge transition area AA2 is located between the main body area AA1 and the shaped boundary a1, the color resistors 20 in the main body area AA1 are regularly arranged, and in order to match the shaped boundary a1, the plurality of color resistors 20 near the shaped boundary a1 in the edge transition area AA2 are arranged in a step manner to adapt to the shape of the shaped boundary a 1. The visible light passes through the color resistor 20 for displaying images, and the color resistor 20 near the irregular boundary a1 is arranged in a step manner, so that the display panel displays images with a sawtooth phenomenon at the irregular boundary a 1. In order to alleviate the aliasing phenomenon in the area at the shaped boundary a1 when the display panel is displaying, the opening area of the pixel in the edge transition area AA2 where the color resistor 20 is located may be reduced, so that the brightness of the pixel in the edge transition area AA2 is less than the brightness of the pixel in the main body area AA1 when the display panel is displaying, and the edge transition area AA2 has a transition effect between the main body area AA1 and the non-display area, thereby alleviating the aliasing phenomenon at the shaped boundary a1 when the display panel is displaying. Since the opening area of the pixel corresponding to the color resistor 20 in the edge transition area AA2 needs to be reduced, the color resistor 20 in the edge transition area AA2 needs to be partially shielded from light to meet the brightness requirement of the pixel.
The display area AA includes a plurality of color resists 20 disposed on one side of the substrate 10, and a first blue color resist 30 is disposed in the edge transition area AA2, wherein the first blue color resist 30 has a grid structure including a plurality of meshes 31. In the edge transition area AA2, only a partial area of the color resistor 20 can be exposed through the mesh 31, and there is an overlapping area of the color resistor 20 and the first blue color resistor 30, and the overlapping area has a low light transmittance, so that the light blocking effect is achieved, and the brightness of the pixel where the color resistor 20 is located in the edge transition area AA2 can be reduced. The principle of the first blue color resistor 30 for shading light is as follows: a part of visible light is lost when passing through the blue color resists, and thus, the transmittance of the region where the color resist 20 and the first blue color resist 30 overlap can be reduced. Moreover, when the color resists 20 are colors other than blue, the transmittance of visible light passing through the color resists of two different colors is low, and the light-shielding effect of the first blue color resist 30 is significant.
Also, the opening area of the pixels in the display panel can be matched by adjusting the size of the mesh 31 in the first blue color resist 30. Because the color resistor 20 and the first blue color resistor 30 can be made of similar materials, the adhesion capability of the color resistor 20 and the first blue color resistor 30 is better, the phenomenon of peeling between the color resistor 20 and the first blue color resistor 30 is effectively avoided, and the first blue color resistor 30 can be arranged on one side of the color resistor 20 far away from the substrate 10, so that the color resistor 20 can completely cover the substrate 10, and the risk of peeling the color resistor 20 from the substrate 10 in the edge transition area AA2 is reduced.
In this embodiment, the material of the first blue color resistor 30 may be a common material for manufacturing a color resistor in a color filter substrate, and the manufacturing process thereof is a common process for manufacturing a color resistor in a color filter substrate, and the same mask plate may be used for manufacturing the first blue color resistor 30 and the color resistor 20, so that the process is effectively reduced, and the production cost is reduced.
With continuing reference to fig. 3 and fig. 4, optionally, the first color resistor 21, the second color resistor 22 and the third color resistor 23 are respectively one of a red color resistor, a green color resistor and a blue color resistor, and the first color resistor 21, the second color resistor 22 and the third color resistor 23 are different.
Specifically, through simulation and experimental detection, after the red color resistance and the blue color resistance are superposed, the transmittance of visible light is close to 0; when the green color resistance and the blue color resistance are superposed, the transmittance of visible light is reduced by about 90 percent compared with the condition that the green color resistance is not superposed with the blue color resistance; when the blue color resistance is superposed with one blue color resistance, the transmittance of visible light is reduced by about 80 percent compared with that of a single blue color resistance; so that the portion of the color resistor 20 in the edge transition area AA2 that needs to be shielded from light can be shielded from light by superimposing the first blue color resistor 30.
It should be noted that, this embodiment exemplarily shows that the color resistor 20 is one of a red color resistor, a green color resistor and a blue color resistor, and the color resistor 20 may also be other colors in other embodiments of the present invention, which is not repeated herein.

Specifically, the sizes of the color resistors 20 in the main area AA1 and the edge transition area AA2 are the same, and the size of the color resistor 20 in the edge transition area AA2 does not need to be additionally set, so that the design difficulty of the color film substrate can be reduced, and the cost can be reduced. Moreover, the color resistors 20 with the same color can be set by the same process, and the same mask can be reused when the color resistors 20 with different colors are manufactured, so that the manufacturing process of the color film substrate is simplified, and the production cost is reduced.

The opening area of the pixel corresponding to the color resistor 20 in the main body area AA1 is larger than the opening area of the pixel corresponding to the color resistor 20 in the edge transition area AA2, so that the sawtooth phenomenon of the area corresponding to the special-shaped boundary a1 when the display panel displays is effectively relieved, and the display effect is better improved.
