[0039] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0040] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by people with ordinary skills in the field to which this disclosure belongs. The words "first", "second" and similar words used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one", "an" or "the" do not indicate a quantity limitation, but rather indicate the existence of at least one. Words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0041] In the prior art, a thin film transistor-liquid crystal display (TFT-LCD) is a display panel that uses microelectronics processing technology to combine thin film transistors (TFTs) with a liquid crystal display panel. Specifically, the microelectronics processing technology used on silicon is transplanted to large-area glass to produce a TFT array. The resulting array substrate with TFTs is then aligned with another color filter substrate with a color filter layer. After undergoing post-processing steps such as polarizer lamination, the liquid crystal display panel is finally obtained. In a liquid crystal display panel, the array substrate generally includes pixel electrodes and thin film transistors that control the switching of sub-pixels, while the color filter substrate generally includes a common electrode, a black matrix, and a color resist structure. When an electric field that controls the deflection of liquid crystal molecules is formed between the pixel electrode and the common electrode, light passes through the array substrate and irradiates the liquid crystal molecule layer. After being deflected by the liquid crystal molecules, the light is emitted to the color filter substrate. Then, after passing through the red, green, and blue color resists on the color filter substrate, it can be emitted from the display panel surface in the form of red, green, and blue light, ultimately forming a pattern display on the display panel surface.

[0042] like Figure 1 As shown, an exemplary array substrate 10 is provided. The array substrate 10 includes a substrate, a plurality of gate lines 11 extending along the X direction, and a plurality of data lines 12 extending along the Y direction. The plurality of gate lines 11 and the plurality of data lines 12 are cross-arranged and define a plurality of pixel units. Each of the plurality of pixel units includes a display electrode 13, wherein the display electrode can be a common electrode or a pixel electrode. This embodiment is described by taking the display electrode as a pixel electrode as an example.

[0043] It should be noted that, in the embodiment of the present disclosure, the pixel unit not only includes the above-mentioned pixel electrode 13, but also may include a thin film transistor and a common electrode; wherein, the pixel electrode 13 adopts a slit electrode, and the common electrode adopts a plate electrode, so the common electrode is closer to the substrate than the pixel electrode. In addition, in the embodiment of the present disclosure, the gates of the thin film transistors in the pixel units arranged side by side in the X direction are connected to the same gate line 11, and the sources of the thin film transistors in the pixel units arranged side by side in the Y direction are connected to the same data line 12 as an example. The pixel electrode 13 in each pixel unit is connected to the drain of the thin film transistor. In the embodiment of the present disclosure, the X direction and the Y direction can also be any other directions, as long as the X direction and the Y direction intersect, and no specific limitation is made here.

[0044] like Figure 1As shown, the pixel electrode 13 in the array substrate 10 includes at least one electrode portion 131. Each electrode portion 131 includes a main chain electrode 1311 extending along the Y direction and multiple branch electrodes 1312 extending along the X direction. The multiple branch electrodes 1312 are all electrically connected to the main chain electrode 1311. This embodiment is described by taking the pixel electrode 13 including two electrode portions 131 as an example.

[0045] Figure 2 for Figure 1 The light effect diagram of the array substrate is shown in FIG. Figure 2 As shown, the main chain electrode 1311 region has a disordered arrangement of liquid crystal molecules. Due to the disordered arrangement of liquid crystal molecules, the main chain electrode region cannot transmit light normally. Therefore, under white screen conditions, the disordered region has little contribution to the transmittance. However, under black screen conditions, the disordered region will leak light, resulting in increased dark state brightness, which in turn affects the display contrast.

[0046] In order to solve the above problems, the present disclosure provides an array substrate. Figure 3 As shown, the array substrate and Figure 1 The structures of the array substrates shown are substantially the same, with the difference being that the array substrate further includes a black matrix layer 14 disposed on the side of the pixel unit facing away from the substrate. The black matrix layer 14 includes a plurality of openings 141 and light shielding portions 142. The openings 141 of the black matrix layer are disposed corresponding to the pixel electrodes 13. The orthographic projections of the openings 141 on the substrate cover the orthographic projections of the branch electrodes 1312 of the pixel electrode 13 on the substrate. The orthographic projections of the light shielding portions 142 on the substrate cover the orthographic projections of the gate lines 11, data lines 12, and main chain electrodes 1311 on the substrate.

[0047] In this embodiment, since the light-shielding portion 142 of the black matrix layer 14 covers not only the gate line 11 and the data line 12, but also the main chain electrode 1311, when the array substrate is in a black screen, the disordered arrangement area of the liquid crystal molecules corresponding to the main chain electrode 1311 in the pixel unit is shielded by the black matrix layer 14, which can reduce the risk of light leakage in the area and reduce the black state brightness. Under a white screen, the disordered arrangement area of the liquid crystal molecules itself contributes little to the light transmittance and has low luminous efficiency. After being shielded by the black matrix layer 14, it has little effect on the white state brightness, which is equivalent to the white state brightness remaining unchanged while the black state brightness is reduced, thereby improving the display contrast.

[0048] Optionally, the shapes of the main chain electrode 1311 and the branch electrode 1312 can be set according to specific circumstances and are not specifically limited here. Figure 1As shown, both the main chain electrode 1311 and the branch electrode 1312 are in the shape of strips. When both the main chain electrode 1311 and the branch electrode 1312 are in the shape of strips, the area occupied by the main chain electrode 1311 and the branch electrode 1312 in the opening 141 can be reduced, thereby increasing the light transmittance. In addition, the number of main chain electrodes 1311 and branch electrodes 1312 can also be set according to specific circumstances, and will not be explained here one by one.

[0049] Furthermore, to increase light transmittance, the main chain electrode 1311 and the branch electrode 1312 may be made of a light-transmitting material, such as metal oxide, etc. Preferably, the main chain electrode 1311 and the branch electrode 1312 are made of indium tin oxide (ITO).

[0050] Optionally, the number of electrode parts 131 in each display electrode 13 may be one or more. When the number of electrode parts 131 is more than one, the main chain electrodes 1311 in adjacent electrode parts 131 are located on different sides of the branch electrodes 1312. Figure 1 As shown, this embodiment is described by taking the number of electrode parts 131 as two as an example, wherein the two electrode parts 131 are respectively a first electrode part and a second electrode part. Figure 1 In the embodiment, since the main chain electrodes 1311 of the first electrode portion and the second electrode portion are located on different sides of the branch electrodes 1312, that is, the main chain electrode 1311 of the first electrode portion is located on the left side of its branch electrodes 1312, and the main chain electrode 1311 of the second electrode portion is located on the right side of its branch electrodes 1312, the branch electrodes 1312 connected to the main chain electrode 1311 can be distributed more evenly on different sides of the main chain electrode 1311, thereby improving the symmetry of the pixel electrode 13 and further improving the uniformity of the transmittance of the display panel.

[0051] Optionally, the main chain electrodes 1311 in the adjacent electrode parts 131 are electrically connected via the connecting electrode 1313. For example, Figure 1 As shown, the main chain electrode 1311 in the first electrode portion is connected to the main chain electrode 1311 in the second electrode portion via the connecting electrode 1313. When a signal is written to the pixel electrode 13 via the data line, the signal on the main chain electrode 1311 can be transmitted to each branch electrode 1312 via the connecting electrode 1313, thereby cooperating with the common electrode to realize the display function.

[0052] Optionally, the connecting electrode 1313 is located between adjacent electrode portions 131 and has the same extending direction as the branch electrodes 1312 .

[0053] In this embodiment, since the connecting electrode 1313 is located between adjacent electrode portions 131 and extends in the same direction as the branch electrodes 1312, the light transmittance of the pixel unit can be improved. Preferably, the extending direction of the connecting electrode 1313 is parallel to the extending direction of the branch electrodes 1312.

[0054] Optionally, the angle between the connecting electrode 1313 and the main chain electrode 1311 is greater than or equal to 90 degrees. In an embodiment, by setting the angle between the connecting electrode 1313 and the main chain electrode 1311 to be greater than or equal to 90 degrees, the transmittance of the display panel can be prevented from being affected by the length of the main chain electrode 1311.

[0055] Optionally, the angle between the extension direction of the branch electrode 1312 and the gate line 11 ranges from 7 degrees to 20 degrees.

[0056] like Figure 1 As shown, the included angle γ between the extension direction of the branch electrode 1312 and the gate line 11 ranges from 7 degrees to 20 degrees.

[0057] If the angle γ is set too small, the liquid crystal will need to be deflected at a larger angle, which will cause a delay in the display panel displaying the image. If the angle γ is set too large, the liquid crystal will need to be deflected too small, making it difficult to determine the deflection direction of the liquid crystal during deflection. The time required to determine the deflection direction is longer, which will cause a delay in the display panel displaying the image.

[0058] Therefore, in this embodiment, the angle γ between the extension direction of the branch electrode 1312 and the gate line 11 ranges from 7 degrees to 20 degrees, which does not cause delay in displaying images on the display panel.

[0059] Optionally, the pixel units are arranged in an array on the substrate, each pixel unit includes multiple sub-pixels, the shapes of the openings 141 of the black matrix layer 14 corresponding to each sub-pixel in each pixel unit are different, the shapes of the openings 141 of the black matrix layer 14 corresponding to each sub-pixel of adjacent pixel units are also different, and pixel units with the same shape of the openings 141 are arranged at intervals.

[0060] Specifically, such as Figure 4 and Figure 5 As shown, this embodiment is described by taking 4 pixel units and each pixel unit including 3 sub-pixels as an example. In this embodiment, four pixel units are arranged in an array on the substrate, and each pixel unit includes three sub-pixels. The three sub-pixels correspond to Figure 3The openings 141 of the black matrix layer 14 shown are all shaped differently. Furthermore, the shapes of the openings 141 of the black matrix layer 14 corresponding to the sub-pixels of adjacent pixel units are all different. Pixel units with the same opening 141 shape are spaced apart, i.e., the sub-pixels in two pixel units on a diagonal line have the same opening 141 shape corresponding to the black matrix layer 14. This ensures the same transmittance in two adjacent rows of pixel units, thereby improving horizontal mura and viewing angles.

[0061] Optionally, the width of the main chain electrode 1311 can be greater than or equal to 2.3 μm and less than or equal to 3 μm. In other words, the width of the main chain electrode 1311 is neither too narrow nor too wide. This can prevent the main chain electrode 1311 from being broken due to a narrow width, and can also prevent the transmittance of the display panel from being affected by a wide width of the main chain electrode 1311.

[0062] Furthermore, the width of the branch electrode 1312 can be greater than or equal to 1.3 μm and less than or equal to 2.2 μm. In other words, the width of the branch electrode 1312 can be smaller than the width of the main electrode 1311, and the width of the branch electrode 1312 is not too narrow, thereby preventing the branch electrode 1312 from breaking while improving the transmittance of the display panel.

[0063] Alternatively, as Figure 3 As shown, the light shielding portion 142 includes a main portion and a protruding portion. The orthographic projection of one protruding portion on the substrate covers the orthographic projection of one main chain electrode 1311 on the substrate. The width of the protruding portion ranges from 13 to 25 microns. In this embodiment, since the width of the protruding portion ranges from 13 to 25 microns, the display contrast can be improved while maintaining the aperture ratio.

[0064] In a second aspect, embodiments of the present disclosure provide a display panel comprising a color filter substrate and an array substrate. Specifically, the array substrate comprises a base, a plurality of gate lines and a plurality of data lines disposed on the base, the plurality of gate lines and the plurality of data lines being intersectingly disposed to define a plurality of pixel units. Each of the plurality of pixel units comprises a display electrode; wherein the display electrode comprises at least one electrode portion; each electrode portion comprises a main chain electrode and a plurality of branch electrodes, and the plurality of branch electrodes are electrically connected to the main chain electrode.

[0065] The color filter substrate includes a black matrix layer and a color resist structure. The black matrix layer includes multiple openings and light shielding portions, and the color resist structure is arranged at the openings of the black matrix. The black matrix layer is arranged on the side of the pixel unit facing away from the substrate. The orthographic projection of an opening on the substrate covers the orthographic projection of a branch electrode of a display electrode on the substrate, and the orthographic projection of the light shielding portion on the substrate covers the orthographic projection of the gate line, data line, and main chain electrode on the substrate.

[0066] In this embodiment, since the light-shielding portion of the black matrix layer covers not only the gate lines and data lines, but also the main chain electrodes, under a black screen, the disordered arrangement area of the liquid crystal molecules corresponding to the main chain electrodes in the pixel unit is shielded by the black matrix layer, which can reduce the risk of light leakage in this area and reduce the black state brightness. Under a white screen, the disordered arrangement area of the liquid crystal molecules itself contributes little to the light transmittance and has low luminous efficiency. After being shielded by the black matrix layer, it has little effect on the white state brightness, which is equivalent to the white state brightness remaining unchanged while the black state brightness is reduced, thereby improving the contrast of the display panel.

[0067] The following embodiments are described by taking the black matrix layer disposed on the color filter substrate as an example. The principle is the same as that of the black matrix layer disposed on the array substrate. Therefore, the principles and effects of the following embodiments are not described in detail.

[0068] Optionally, each display electrode includes a plurality of electrode sections, and the main-chain electrodes in adjacently arranged electrode sections are located on different sides of the branch-chain electrodes.

[0069] Optionally, the main chain electrodes in adjacent electrode portions are electrically connected via a connecting electrode.

[0070] Optionally, the connecting electrode is located between adjacent electrode portions and has the same extension direction as the branch electrodes.

[0071] Optionally, the extending direction of the connecting electrode is parallel to the extending direction of the branch electrodes.

[0072] Optionally, the angle between the connecting electrode and the main chain electrode is greater than or equal to 90 degrees.

[0073] Optionally, the angle between the extending direction of the branch electrode and the gate line is in the range of 7 degrees to 20 degrees.

[0074] Optionally, the pixel units are arranged in an array on the substrate, each pixel unit includes multiple sub-pixels, the opening shapes of the black matrix layer corresponding to each sub-pixel in each pixel unit are different, the shapes of the openings of the black matrix corresponding to each sub-pixel of adjacent pixel units are all different, and pixel units with the same opening shape are arranged at intervals.

[0075] Optionally, the width of the main chain electrode is greater than or equal to 2.3 micrometers and less than or equal to 3 micrometers, and the width of each branch electrode is greater than or equal to 1.3 micrometers and less than or equal to 2.2 micrometers.

[0076] Optionally, the light shielding portion includes a main body portion and a protruding portion, an orthographic projection of one protruding portion on the substrate covers an orthographic projection of one main chain electrode on the substrate, and a width of the protruding portion ranges from 13 to 25 microns.

[0077] In a third aspect, an embodiment of the present disclosure provides a display device, which includes the above-mentioned array substrate or the above-mentioned display panel.

[0078] It is understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present disclosure, and the present disclosure is not limited thereto.
