Description
Technical Field
The invention relates to the technical field of liquid crystal display, in particular to a color film substrate, a manufacturing method thereof and a liquid crystal display panel.
Background
A Liquid Crystal Display (LCD) has advantages of good picture quality, small size, light weight, low driving voltage, low power consumption, no radiation, and relatively low manufacturing cost, and is dominant in the field of flat panel displays.
Liquid crystal display devices are now gradually developed toward wide viewing angles, and wide viewing angles can be realized by using liquid crystal display devices of an in-plane switching mode (IPS) or a fringe field switching mode (FFS). The wide viewing angle design enables the user to see a complete and undistorted picture from all directions. However, in the current society, people pay more and more attention to protecting their privacy, and do not like to take out and share with people. In public places, the content is always expected to be kept secret when the user watches a mobile phone or browses a computer. Therefore, the display with single viewing angle mode has not been able to satisfy the user's requirement. In addition to the requirement of a wide viewing angle, there is also a need to be able to switch or adjust the display device to a narrow viewing angle mode where privacy is required.
In order to realize fast switching between wide and narrow viewing angle modes, an electrode layer is additionally arranged in a color film, and the liquid crystal display device is controlled by the electrode layer to switch between wide and narrow viewing angles.
Fig. 1 is a schematic structural diagram of a conventional color filter substrate. As shown in fig. 1, the color filter substrate 20 includes a substrate 22, and a black matrix 23, a color filter layer 24, a first photo-cured planarization layer 25, an electrode layer 26, and a second photo-cured planarization layer 27 sequentially disposed on the substrate 22. The color film layer 24 includes a red resist 241, a green resist 242, and a blue resist 243. The first photo-curing flat layer 25 and the second photo-curing flat layer 27 need to be cured by UV light, and the UV light may damage the blue-blocking material, so that the display screen of the liquid crystal display device has a blue screen mura problem. In addition, the existing color film substrate 20 has a complex structure and a high manufacturing cost.

the foregoing and other technical matters, features and effects of the present invention will be apparent from the following detailed description of preferred embodiments, which is to be read in connection with the accompanying drawings. While the present invention has been described in connection with the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but is intended to cover various modifications, equivalent arrangements, and specific embodiments thereof.
Fig. 2 is a schematic structural diagram of a liquid crystal display panel according to a first embodiment of the invention at a wide viewing angle. Fig. 3 is a schematic structural diagram of a liquid crystal display panel according to a first embodiment of the invention at a narrow viewing angle. As shown in fig. 2 and fig. 3, in the present embodiment, the liquid crystal display panel 10a includes a color filter substrate 12a, an array substrate 14 disposed opposite to the color filter substrate 12a, and a liquid crystal layer 15 located between the color filter substrate 12a and the array substrate 14. In the embodiment, the liquid crystal display panel 10a of the invention is an hva (hybrid View angle) type display panel, and can switch between a narrow viewing angle and a wide viewing angle to achieve the purpose of anti-peeping.
The liquid crystal display panel 10a of the present invention is suitable for a liquid crystal display panel 10a of an in-plane switching (IPS) mode, a Fringe Field Switching (FFS) mode, or the like, in which the common electrode 143 and the pixel electrode 145 are both formed on the array substrate 14, and when a driving electric field is applied between the common electrode 143 and the pixel electrode 145, liquid crystal molecules rotate in a plane substantially parallel to the array substrate 14, thereby obtaining a wide viewing angle.
As shown in fig. 2 and fig. 3, the color film substrate 12a includes a substrate 121, a black matrix 122, a thermosetting planarization layer 123, an electrode layer 124, and a color film layer 126. The black matrix 122 is disposed on the substrate 121, the thermosetting flat layer 123 is disposed on the substrate 121, and covers the black matrix 122; the electrode layer 124 is disposed on the thermosetting flat layer 123, and the color film layer 126 is disposed on the electrode layer 124, i.e., the electrode layer 124 is disposed between the thermosetting flat layer 123 and the color film layer 126.
In this embodiment, the color film 126 includes a first color resist layer 126a, a second color resist layer 126b and a third color resist layer 126c, and the first color resist layer 126a, the second color resist layer 126b and the third color resist layer 126c are sequentially spliced to form the color film 126, that is, the color film 126 is in a band shape. In order to avoid the influence of the color film layer 126 on the electric field and thus the deflection of the liquid crystal molecules, the dielectric constants and the film thicknesses of the first color resist layer 126a, the second color resist layer 126b and the third color resist layer 126c are substantially the same or completely the same, so that the electric fields passing through the first color resist layer 126a, the second color resist layer 126b and the third color resist layer 126c are kept the same. Further, the first color resist 126a, the second color resist 126B and the third color resist 126c are made of color resist materials of three colors of red (R), green (G) and blue (B), respectively, and correspond to sub-pixels (sub-pixels) of the three colors of red, green and blue, respectively.
In the present embodiment, the black matrix 122 is directly disposed on the substrate 121 and located below the color film layer 126, and preferably, the black matrix 122 is correspondingly disposed at a joint of the first color resist layer 126a and the second color resist layer 126b, a joint of the second color resist layer 126b and the third color resist layer 126c, and a joint of the first color resist layer 126a and the third color resist layer 126 c.
In this embodiment, the thermosetting planarization layer 123 planarizes the electrode layer 124. Since the thermosetting flat layer 123 is cured by heat, the third color resist layer 126c (blue resist material) is not damaged, and the thermosetting flat layer 123 is not in direct contact with the color film layer 126, so that the risk of displaying the blue image mura of the liquid crystal display panel 10 can be effectively reduced.
As shown in fig. 2 and 3, in order to apply a voltage signal to the electrode layer 124 on the color filter substrate 12a, the electrode layer 124 may be electrically connected to the array substrate 14 through the conductive adhesive 13 in the peripheral non-display region of the liquid crystal display panel 10 a. The non-display area of the color film layer 126 is provided with a through hole 101, and the conductive adhesive 13 can pass through the through hole 101 to be electrically connected with the electrode layer 124. In this embodiment, since the thermal curing flat layer 123 cannot be patterned, the electrode layer 124 needs to be disposed on the thermal curing flat layer 123, so as to conveniently open the through hole 101 on the color film layer 126, so that the conductive adhesive 13 penetrates through the through hole 101 to be electrically connected to the electrode layer 124.
As shown in fig. 2 and 3, the array substrate 14 includes a gate insulating layer 141, an insulating protective layer 142, a common electrode 143(common electrode), an insulating spacer 144, and a pixel electrode 145(pixel electrode) on a surface facing the liquid crystal layer 15. The gate insulating layer 141 is formed on the surface of the array substrate 14 facing the liquid crystal layer 15, the insulating protective layer 142 is located on the gate insulating layer 141, the common electrode 143 is formed on the insulating protective layer 142, the insulating spacer layer 144 is formed on the common electrode 143, and the pixel electrode 145 is formed on the insulating spacer layer 144, but the present invention is not limited thereto, and the structure and the order between the respective layers may be appropriately adjusted.
Fig. 4 is a circuit diagram of the array substrate of the present invention. As shown in fig. 4, the array substrate 14 is further provided with a scan line 146 and a data line 147, wherein the scan line 146 and the data line 147 intersect with each other to define a plurality of sub-pixels SP (sub-pixels) arranged in an array. A pixel electrode 145 and a thin film transistor 148 are provided in each sub-pixel SP, and the thin film transistor 148 is located near a position where the scan line 146 and the data line 147 cross. Each tft 148 includes a gate electrode electrically connected to the corresponding scan line 146, a source electrode electrically connected to the corresponding data line 147, and a drain electrode electrically connected to the corresponding pixel electrode 145.
Referring to fig. 2 and 4, a gate insulating layer 141 is formed on the surface of the array substrate 14 facing the liquid crystal layer 15 and covers the scan lines 146 and the gates of the tfts 148, and an insulating protective layer 142 is formed on the gate insulating layer 141 and covers the data lines 147 and the sources and drains of the tfts 148. The insulating spacer layer 144 is located between the common electrode 143 and the pixel electrode 145 to perform an insulating function.
In this embodiment, the electrode layer 124 of the color filter substrate 12a, the common electrode 143 of the array substrate 14, and the pixel electrode 145 may be made of a transparent conductive material such as Indium Tin Oxide (ITO) or Indium Zinc Oxide (IZO). The electrode layer 124 is used for controlling the liquid crystal display panel 10a to switch between a wide viewing angle mode and a narrow viewing angle mode, and different control voltages are applied to the electrode layer 124, so that the liquid crystal display panel 10a can be switched between the wide viewing angle mode and the narrow viewing angle mode; the common electrode 143 is used to apply a common voltage (i.e., Vcom) at the time of screen display; the pixel electrode 145 is formed in each sub-pixel SP (see fig. 4).
In the embodiment, the pixel electrode 145 is located above the common electrode 143 with the insulating spacer 144 therebetween, but the invention is not limited thereto. In other embodiments, the positions of the pixel electrode 145 and the common electrode 143 may be replaced with each other. In addition, when the liquid crystal display panel 10a of an in-plane switching (IPS) mode is employed, the common electrode 143 and the pixel electrode 145 may also be located in the same layer and insulated from each other.
In this embodiment, the liquid crystal molecules in the liquid crystal layer 15 are positive liquid crystal molecules, and the positive liquid crystal molecules have an advantage of fast response. As shown in fig. 2, in an initial state (i.e., when no voltage is applied to the liquid crystal display panel 10 a), the positive liquid crystal molecules in the liquid crystal layer 15 are in a lying posture substantially parallel to the color filter substrate 12a or the array substrate 14, and the long axis direction of the positive liquid crystal molecules is substantially parallel to the surface of the color filter substrate 12a or the array substrate 14. However, in practical applications, a small initial pretilt angle may be provided between the positive liquid crystal molecules in the liquid crystal layer 15 and the color filter substrate 12a or the array substrate 14, and the range of the initial pretilt angle may be less than or equal to 10 degrees, that is: 0 DEG ≦ theta ≦ 10 DEG, but the present invention is not limited to positive liquid crystals.
Fig. 5 is a schematic structural diagram of a liquid crystal display panel according to a second embodiment of the invention at a wide viewing angle. As shown in fig. 5, the liquid crystal display panel 10b of the present embodiment has substantially the same structure as the liquid crystal display panel 10a of the first embodiment, and is different in the structure of the color filter substrate 12 b.
Specifically, the electrode layer 124 for controlling the switching of the viewing angle, which is disposed on the color filter substrate 12b, is made of a transparent conductive material such as ITO or IZO, and the resistance of ITO or IZO is generally large, so that the resistive load of the electrode layer 124 is large, the signal delay is large in the signal transmission process, the voltage waveform may be distorted in the transmission process, and the display image quality is abnormal due to the waveform distortion or signal attenuation.
Therefore, the color filter substrate 12b of the present invention is further provided with metal conductive strips 125 electrically connected to the electrode layer 124, the metal conductive strips 125 are made of metal with low resistivity, such as Mo, Al, Au, Ag, Cu, and the like, the metal conductive strips 125 respectively extend along the direction of each scan line 146 and/or each data line 147, and the metal conductive strips 125 and the black matrix 122 are disposed in an up-and-down overlapping manner, that is, the metal conductive strips 125 are located right below the black matrix 122. The line width of the metal conductive strips 125 is preferably smaller than the line width of the black matrix 122, so that the metal conductive strips 125 are completely covered by the black matrix 122. Although the metal conductive strips 125 are made of metal and are opaque, the aperture ratio and the transmittance of each sub-pixel SP are not affected by the metal conductive strips 125 because the metal conductive strips are disposed at the position right below the black matrix 122.
Fig. 6 is a schematic flow chart of a manufacturing method of a color film substrate according to the present invention. Referring to fig. 2 to 6, the method for manufacturing a color filter substrate of the present invention includes the steps of:

Specifically, the substrate 121 is made of, for example, transparent glass, but not limited thereto.
In step S2, the black matrix 122 is formed on the substrate 121.
In step S3, the thermosetting flat layer 123 is formed on the substrate 121, and the black matrix 122 is covered with the thermosetting flat layer 123.
Specifically, the thermosetting flat layer 123 is cured by heat, which does not damage the blue resist material, and can effectively reduce the risk of displaying the blue mura on the liquid crystal display panels 10a and 10 b.
In step S4, the electrode layer 124 is formed on the thermally cured planarization layer 123.
Specifically, the electrode layer 124 is used to control the liquid crystal display panels 10a and 10b to perform wide and narrow viewing angle switching, and the liquid crystal display panels 10a and 10b can be switched between a wide viewing angle mode and a narrow viewing angle mode by applying different control voltages to the electrode layer 124.
In step S5, metal conductive strips 125 are fabricated on the electrode layer 124.
Specifically, the metal conductive strips 125 are used to improve the conductivity of the electrode layer 124, so as to avoid the problems of abnormal display image quality caused by waveform distortion or signal attenuation due to large signal delay in the signal transmission process and possible distortion of the voltage waveform in the transmission process due to a large resistive load of the electrode layer 124.
In step S6, a color film layer 126 is formed on the electrode layer 124, and the color film layer 126 covers the electrode layer 124 and the metal conductive strips 125.
Specifically, the color film 126 includes a first color resist layer 126a, a second color resist layer 126b and a third color resist layer 126c, and the first color resist layer 126a, the second color resist layer 126b and the third color resist layer 126c are sequentially spliced to form the color film 126, that is, the color film 126 is in a strip shape. In order to avoid the influence of the color film layer 126 on the electric field and thus the deflection of the liquid crystal molecules, the dielectric constants and the film thicknesses of the first color resist layer 126a, the second color resist layer 126b and the third color resist layer 126c are substantially the same or completely the same, so that the electric fields passing through the first color resist layer 126a, the second color resist layer 126b and the third color resist layer 126c are kept the same.
The black matrix 122 of the color filter substrates 12a and 12b of the present invention is disposed on the substrate 121, the thermosetting planarization layer 123 is disposed on the substrate 121 and covers the black matrix 122, the electrode layer 124 is disposed on the thermosetting planarization layer 123, and the color filter layer 126 is disposed on the electrode layer 124. Because the thermal curing flat layer 123 is thermally cured, the blue resist material is not damaged, and the risk of displaying the blue picture mura by the liquid crystal display panels 10a and 10b can be effectively reduced. In addition, the color film substrates 12a and 12b are simple in structure, and manufacturing cost is reduced.
