The gray scale of each sub-pixel can be independently controlled, and each sub-pixel can be a basic unit for displaying a specific color. Each sub-pixel includes an opening area EA and a non-opening area. The opening area EA is an area in which a color is actually displayed by transmitting light incident on the bottom of the first substrate 3 to the top of the second substrate 5, and the non-opening area is an area for placing a switching element for driving the liquid crystal layer LC and a related signal line.

The extension direction of the scan lines can be parallel to one edge of the first base SUB1 or can be parallel to a direction represented by an arbitrary straight line extending in a specific direction on the first base SUB1. The gates can be formed as protrusions from the scan lines and can be physically connected to the scan lines. As an example, the first conductive layer M1 can contain aluminum-based metals (e.g., aluminum (Al) and aluminum alloys), silver-based metals (e.g., silver (Ag) and silver alloys), copper-based metals (e.g., copper (Cu) or copper alloys), molybdenum-based metals (e.g., molybdenum (Mo) and molybdenum alloys), chromium (Cr), tantalum (Ta), or titanium (Ti).

For example, the ohmic contact layer can be formed of n+ hydrogenated amorphous silicon doped with a high concentration of n-type impurities or can be formed of a silicide. In an embodiment, the active layer ACTL includes an oxide semiconductor and the ohmic contact layer is omitted.

[0027] The second conductive layer M2 is provided on the active layer ACTL and includes a data line, a source of the transistor T, and a drain of the transistor T. The data line can extend in a direction that intersects the extension direction of the scan line, for example, perpendicularly. The data line can supply a data signal to the source.

The source can branch from the data line. In a plan view, the drain can be arranged to be spaced apart from the source with the active layer ACTL interposed therebetween, and the drain can at least partially overlap the gate. As an example, the second conductive layer M2 can be made of aluminum, copper, silver, molybdenum, chromium, titanium, tantalum, or an alloy thereof. Further, for example, the second conductive layer M2 can also have a multi-layer structure having a lower film (e.g., a refractory metal) and a low-resistance upper film formed thereon.

[0028] The first passivation layer PV1 is provided on the second conductive layer M2. The first passivation layer PV1 can be made of an inorganic insulating material and can be provided to cover the transistor T. The first passivation layer PV1 can protect the transistor T and can prevent an undesirable substance from flowing into the active layer ACTL.

[0029] The planar layer PLN can be provided on the first passivation layer PV1 and provided with a plurality of through-holes.

See also Figure 4 and Figure 6The pixel electrode PE includes a main electrode portion MEP and two branch electrode portions BEP connected to the main electrode portion MEP. The two branch electrode portions BEP include a first branch electrode portion BEP1 located in the first domain region DEA1 and a second branch electrode portion BEP2 located in the second domain region DEA2. The pixel electrode layer PEL can be made of a transparent conductive material (e.g., indium tin oxide (ITO), indium zinc oxide (IZO), indium tin zinc oxide (ITZO), or aluminum-doped zinc oxide (AZO), etc.).

[0033] Meanwhile, a first alignment layer ALM1 is disposed on the pixel electrode layer PEL. The first alignment layer ALM1 can control an initial alignment angle of liquid crystals injected into the liquid crystal layer LC.

[0034] Please continue to refer to Figure 1 The second substrate 5 includes a second base SUB2, a black matrix layer BM, a color filter layer CF, a fill layer FIL, and a second alignment layer ALM2.

[0035] The second base SUB2 is disposed to face the first base SUB1. The second base SUB2 can have durability to withstand external impact. The second base SUB2 can be a transparent insulating substrate. For example, the second base SUB2 can be made of a glass substrate, a quartz substrate, a transparent resin substrate, etc.

[0036] The black matrix layer BM is disposed on a surface of the second base SUB2 facing the first substrate 3. The black matrix layer BM is provided with a plurality of matrix openings BMO. The black matrix layer BM can be disposed to overlap the scan lines, the data lines, the transistors T, for example, to overlap the non-opening regions, and can block transmission of light in the non-opening regions.

[0037] The color filter layer CF is disposed on a surface of the second base SUB2 facing the first substrate 3. The color filter layer CF can be a photosensitive organic composition containing pigments for providing colors, and can include, for example, any one of red, green, and blue pigments. As an example, the color filter layer CF can include a plurality of color filter blocks CFP, which overlap the pixel electrode PE in a thickness direction of the display panel 100 and are disposed corresponding to the matrix openings BMO. For example, the color filter blocks CFP can be disposed within the corresponding matrix openings BMO. As an example, any one of the plurality of color filter blocks CFP can display one color of primary colors such as red, green, and blue. In other implementations, the plurality of color filter blocks CFP can display any one of cyan, magenta, yellow, and white.

[0038] The fill layer FIL is disposed on surfaces of the color filter layer CF and the black matrix layer BM facing the first substrate 3.

[0039] Meanwhile, a second alignment layer ALM2 can be disposed on a surface of the filling layer FIL facing the first substrate 3. Similar to the first alignment layer ALM1, the second alignment layer ALM2 can control the initial alignment angle of the liquid crystal injected into the liquid crystal layer LC.

[0040] In addition, the display panel 100 can further include a support layer PSL. The support layer PSL includes support columns PS for maintaining a space in which the liquid crystal layer LC is formed. The support columns PS can be disposed on the first substrate 3 or on the second substrate 5.

[0041] In some embodiments, please continue to refer to Figure 1 The color filter block CFP is provided with at least one light-transmitting part TRP, which is disposed in a spaced-apart manner with the pixel electrode PE and overlaps in the thickness direction of the display panel 100. By providing the light-transmitting part TRP in the color filter block CFP in a spaced-apart and overlapping manner with the pixel electrode PE, the transmittance of the opening area EA can be improved, and the spectrum of the backlight module can be modulated.

[0042] In some embodiments, the light-transmitting part TRP includes an opening OP, which penetrates the color filter block CFP in the thickness direction of the color filter block CFP. The opening design not only improves the transmittance of the area where the pixel electrode PE is located, but also modulates the spectrum of the backlight, reduces scattering, and improves the contrast of the display panel 100.

[0043] The filling layer FIL fills the opening OP. The color filter layer CF includes a main material and a color material doped in the main material. The material of the filling layer is the same as the main material. The filling layer has the same refractive index as the main material of the color filter layer CF, which can reduce the scattering of light at the opening due to the difference in refractive index, and further improve the contrast of the display panel 100. Specifically, the filling layer FIL can include a transparent color resistance material.

[0044] The light-transmitting part TRP includes a plurality of openings OP, and the pixel electrode PE includes a plurality of bent connection parts BCP, and the plurality of openings OP are arranged along the arrangement direction of the plurality of bent connection parts BCP. In this way, the specifications such as color points and color gamut can be accurately controlled. In possible implementations, the plurality of openings OP are uniformly arranged along the arrangement direction of the plurality of bent connection parts BCP, and the color points and color gamut can be uniformly regulated. In possible implementations, the distribution density of a part of the openings OP is greater than that of another part of the openings OP, and the color points and color gamut can be locally regulated. In some embodiments, please refer to Figures 2 to 7The pixel electrode PE includes at least one bending connection part BCP, and the light-transmitting part TRP overlaps the bending connection part BCP. The bending connection part BCP of the pixel electrode PE is prone to appear a dark area. Therefore, the light-transmitting part TRP overlaps the bending connection part BCP, so that the dark area phenomenon can be improved. In an embodiment, the length of the light-transmitting part TRP is greater than or equal to the length of the bending connection part BCP. The length of the light-transmitting part TRP refers to the distance between the left edge and the right edge of the light-transmitting part TRP. The length of the bending connection part BCP refers to the distance between the left edge of the leftmost branch electrode in the bending connection part BCP and the left edge of the rightmost branch electrode in the bending connection part BCP. The width of the light-transmitting part TRP is greater than or equal to the width of the bending connection part BCP. The width of the light-transmitting part TRP refers to the distance between the upper edge and the lower edge of the light-transmitting part TRP. The width of the bending connection part BCP refers to the distance between the upper edge and the lower edge of the bending connection part BCP. In this way, the dark area light leakage can be maximally reduced, and local light leakage residues caused by incomplete coverage can be avoided.

[0045] In an embodiment, referring to Figure 2 and Figure 3 , the at least one bending connection part BCP includes a first bending connection part BCP1 connected between the first branch electrode part BEP1 and the second branch electrode part BEP2. The at least one light-transmitting part TRP includes a first light-transmitting part TRP1 overlapping the first bending connection part BCP1. The area where the first bending connection part BCP1 is located is a crab leg dark area in the middle of the pixel dual domain. The first light-transmitting part TRP1 can accurately improve the light transmittance of the area.

[0046] The first light-transmitting part TRP1 is arranged in the middle of the color filter block CFP. The light-transmitting part TRP can be formed synchronously in the preparation process of the color filter block CFP, thereby reducing the process difficulty. Further, the first light-transmitting part TRP1 can be a partition of the opening of the color filter block CFP. On the one hand, the length of the first light-transmitting part TRP1 can be ensured, thereby ensuring the improvement effect on the crab leg dark area. On the other hand, the process difficulty can be further reduced.

[0047] Specifically, the width of the first bending connection part BCP1 ranges from 4 um to 9 um, and the width of the first light-transmitting part TRP1 ranges from 5 um to 20 um. If the width of the first light-transmitting part TRP1 is too small, the process difficulty of the first light-transmitting part TRP1 increases, and the first light-transmitting part TRP1 is difficult to accurately cover the first bending connection part BCP1. If the width of the first light-transmitting part TRP1 is too large, the color gamut is reduced, and the flow leveling degree of the material filling the light-transmitting part TRP is also reduced.

[0048] In an embodiment, referring to Figure 4 and Figure 5The at least one bending connection portion BCP includes a second bending connection portion BCP2 connected between the main electrode portion MEP and the branch electrode portion BEP, and the at least one light-transmitting portion TRP includes a second light-transmitting portion TRP2 overlapping the second bending connection portion BCP2. The second bending connection portion BCP2 is arranged between the main electrode portion MEP and the branch electrode portion BEP. A dark area is prone to occur in a region where the second bending connection portion BCP2 is located. The second light-transmitting portion TRP2 is arranged to improve the light transmittance of the region. Further, the second light-transmitting portion TRP2 can also overlap the main electrode portion MEP. In this way, the process difficulty of forming the second light-transmitting portion TRP2 can be reduced.

[0049] In the viewing angle along the thickness direction of the display panel 100, the second light-transmitting portion TRP2 is arranged on the side of the color filter block CFP close to the black matrix layer BM. The black matrix layer BM can block stray light at the edge of the panel. The second light-transmitting portion TRP2 is arranged between the color filter block CFP and the black matrix. The second light-transmitting portion TRP2 can improve the dark area through the light-transmitting portion TRP, and can block external stray light from entering the light-transmitting portion TRP through the black matrix layer BM, thereby reducing the interference of stray light. When the second light-transmitting portion TRP2 is an opening, the second light-transmitting portion TRP2 can be formed synchronously when the color filter block CFP is filled in the matrix opening BMO, thereby simplifying the process.

[0050] The second light-transmitting portion TRP2 has two second light-transmitting portions TRP2 arranged at opposite ends of the color filter block CFP. In this way, the viewing angle deviation can be improved.

[0051] In some embodiments, please refer to Figure 4 The support column PS is supported by the black matrix layer BM and is arranged at a distance from the edge of the black matrix layer BM close to the second light-transmitting portion TRP2. In this way, the support column PS can avoid blocking the second light-transmitting portion TRP2, prevent local light leakage or brightness reduction caused by the support column PS, and ensure that the dark state improvement effect of the light-transmitting portion TRP is not weakened.

[0052] The spacing design of the support column PS and the second light-transmitting portion TRP2 can also prevent local light leakage or brightness reduction caused by the collapse of the support column PS. Specifically, the edge of the support column PS close to the second light-transmitting portion TRP2 is spaced apart from the edge of the black matrix layer BM close to the second light-transmitting portion TRP2 by a distance greater than or equal to 8 um, so as to ensure the support effect of the support column PS.

[0053] In some embodiments, please refer to Figure 6 and Figure 7 The at least one bending connection portion BCP includes a first bending connection portion BCP1 and a second bending connection portion BCP2. Correspondingly, the at least one light-transmitting portion TRP includes a first light-transmitting portion TRP1 and a second light-transmitting portion TRP2.

[0054] In some embodiments, referring to Figure 3 , Figure 5 , Figure 7 , the plurality of sub-pixels comprises a first sub-pixel, a second sub-pixel and a third sub-pixel. The plurality of color filter blocks CFP comprises a first color filter block CFPG, a second color filter block CFPR and a third color filter block CFPB, corresponding to the first sub-pixel, the second sub-pixel and the third sub-pixel respectively. For example, the first color filter block CFPG, the second color filter block CFPR and the third color filter block CFPB are green filter block, red filter block and blue filter block respectively. Wherein, the first color filter block CFPG, the second color filter block CFPR and the third color filter block CFPB are all provided with a light transmission part TRP, and the width and length of the light transmission part TRP of the three color filter blocks can be equal to ensure the consistency of the improvement of light transmission rate.

[0055] Optionally, since the color points of the first sub-pixel and the second sub-pixel exceed the standard color point, and the color point of the third sub-pixel is close to the standard color point, considering the color gamut and color point design, the width of the light transmission part TRP of the first color filter block CFPG and the second color filter block CFPR is greater than the width of the light transmission part TRP of the third color filter block CFPB. In other embodiments, the third color filter block CFPB can also not be provided with a light transmission part TRP.

Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more features.
