[0042] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0043] Reference below Figure 1-Figure 10 The color filter substrate 10 according to the first embodiment of the utility model is described.

[0044] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the color filter substrate 10 according to the first embodiment of the utility model includes: a color filter support layer 11 and a color filter 12 .

[0045] Specifically, the color film support layer 11 includes a color film base plate 111 and a black matrix layer 112. The black matrix layer 112 is arranged on one side surface of the color film base plate 111 in the thickness direction. A plurality of mounting grooves 13 arranged in a matrix are formed on the color film support layer 11. In the thickness direction of the color film support layer 11, the mounting grooves 13 penetrate the black matrix layer 112 and penetrate at least part of the color film base plate 111. The plurality of mounting grooves 13 are filled with color films 12.

[0046] Among them, the color film base plate 111 is a light-transmitting member, for example, the color film base plate 111 can be a glass member, and the angle between the observer's line of sight and the thickness direction of the color film substrate 10 is the line of sight angle. It can be understood by those skilled in the art that the color film 12 includes monomers of three colors: red, green and blue, and the monomers of the three colors: red, green and blue are filled in the installation groove 13 in sequence.

[0047] During the operation of the display panel 100, light passes through the color film 12 and the color film bottom plate 111 in sequence, and then is emitted to the external environment. When the light passes through the color film 12 monomer in the installation groove 13 and is emitted from the installation groove 13 toward various angles, a portion of the light can be irradiated on the color film 12 monomer of different colors in the adjacent installation groove 13. In this way, after the light passes through at least two color film 12 monomers of different colors, the color of the light will be distorted under the effect of the color film 12 monomers of different colors, so that outsiders cannot see the image corresponding to this portion of the light.

[0048] In this embodiment, the thickness of the color film 12 can be increased by penetrating the mounting groove 13 through at least a portion of the color film bottom plate 111. On the one hand, when the light passes through the color film substrate 10, when the light passes through the color film 12 in two or more mounting grooves 13, the angle between the light and the thickness direction of the color film substrate 10 will become smaller, thereby reducing the viewing angle of the display panel 100. Thus, the anti-peeping effect of the display panel 100 can be achieved, and there is no need to set an anti-peeping layer on the display panel 100, which can reduce the production cost.

[0049] On the other hand, when the color film 12 becomes thicker, the color intensity of the light passing through the color film 12 is higher and the color is more vivid, thereby improving the effect of the color film substrate 10 .

[0050] At the same time, the portion of the installation groove 13 that passes through the color film bottom plate 111 can form a grating matrix on the color film bottom plate 111, and the light emitted from the side wall of the installation groove 13 will be weakened or even blocked, thereby further improving the anti-peeping effect.

[0051] According to the color film substrate 10 of the first embodiment of the utility model, the viewing angle of the display panel 100 can be reduced to achieve an anti-peeping effect, and there is no need to set an anti-peeping layer on the display panel 100, which can reduce production costs.

[0052] In some embodiments of the present invention, the mounting groove 13 is formed by etching. The etching efficiency and precision are high, which can improve the production efficiency and the yield rate of the color filter substrate 10.

[0053] In some embodiments of the present invention, Figure 3-Figure 5 As shown, on the projection plane perpendicular to the length direction of the installation groove 13, the shape of the installation groove 13 is a trapezoid. In this way, the coverage area of ​​the color filter 12 on the color filter bottom plate 111 can be increased, thereby improving the effect of the color filter substrate 10.

[0054] In some embodiments of the present invention, Figure 3-Figure 5As shown, on the projection plane perpendicular to the length direction of the mounting groove 13 , the shape of the mounting groove 13 is an isosceles trapezoid, so that the light is more uniform after passing through the mounting groove 13 , thereby further improving the effect of the color filter substrate 10 .

[0055] The width dimension of the bottom wall of the mounting groove 13 is smaller than the width dimension of the opening of the mounting groove 13. It can be understood that in the process of filling the color film 12 in the mounting groove 13, the size of the mounting groove 13 gradually decreases from the outside to the inside, which can reduce the difficulty of filling and reduce the probability of a cavity being generated between the color film 12 and the inner wall of the mounting groove 13, thereby improving production efficiency and yield rate.

[0056] The following describes the anti-peeping angle by taking two adjacent mounting grooves 13 as an example. For example, the two mounting grooves 13 are respectively the first mounting groove 13 and the second mounting groove 13. On the projection surface perpendicular to the length direction of the mounting groove 13, it can be understood that, Figure 3-Figure 5 As shown, the angle between the line connecting the side of the opening of the first mounting groove 13 away from the second mounting groove 13 and the side of the bottom wall of the second mounting groove 13 close to the first mounting groove 13, and the color film substrate 10 in the thickness direction is the maximum value of the angle between the light emitted from the first mounting groove 13 and the color film substrate 10 in the thickness direction, that is, the angle between the line connecting the side of the opening of the first mounting groove 13 away from the second mounting groove 13 and the side of the bottom wall of the second mounting groove 13 close to the first mounting groove 13, and the color film substrate 10 in the thickness direction is the maximum value of the visible angle.

[0057] Assuming the viewing angle is β, the depth of the mounting groove 13 is H, and the angle between the side walls of the mounting groove 13 on both sides in the width direction and the plane parallel to the bottom wall of the mounting groove 13 is The width dimension of the opening position of the installation groove 13 is W.

[0058] The viewing angle

[0059] In some embodiments of the present invention, Figure 5 As shown, the angle between the side walls of the mounting groove 13 on both sides in the width direction and the plane parallel to the bottom wall of the mounting groove 13 is For example, the angle between the side walls of the mounting groove 13 on both sides in the width direction and the plane parallel to the bottom wall of the mounting groove 13 is greater than or equal to 45° and less than or equal to 60°. It can be 45°, 50°, 55°, 57° or 60°, so that the parameters of the mounting groove 13 can meet the use requirements. In the process of product design, the angle between the side walls of the mounting groove 13 on both sides in the width direction and the plane parallel to the bottom wall of the mounting groove 13 can be adjusted as needed. So as to meet more product design needs.

[0060] In some embodiments of the present invention, Figure 5 As shown, the depth H of the mounting groove 13 is not less than 10um. For example, the depth H of the mounting groove 13 can be 10um, 11um, 12um, 15um or 20um, so that the depth H of the mounting groove 13 can meet the use requirements. In the process of product design, the depth H of the mounting groove 13 can be adjusted as needed to meet more product design requirements.

[0061] In some embodiments of the present invention, Figure 5 As shown, the width dimension W of the opening position of the mounting groove 13 is greater than or equal to 20um and less than or equal to 30um. For example, the width dimension W of the opening position of the mounting groove 13 can be 20um, 21um, 23um, 25um, 26um or 30um. Thus, the width dimension W of the opening position of the mounting groove 13 can meet the use requirements. During the product design process, the width dimension W of the opening position of the mounting groove 13 can be adjusted to meet more product design requirements.

[0062] In some embodiments of the present invention, Figure 6 As shown, the length of the mounting groove 13 is greater than or equal to 75um and less than or equal to 90um. For example, the length of the mounting groove 13 can be 75um, 76um, 80um, 84um, 87um or 90um, so that the length of the mounting groove 13 can meet the use requirements. In the process of product design, the length of the mounting groove 13 can be adjusted to meet more product design requirements.
