The embodiment of the invention provides a display panel and a manufacturing method thereof. The following will describe in detail.
Example 1
An embodiment of the present invention provides a display panel 10, as shown in fig. 1 to 3, the display panel 10 includes:
the array substrate 100, the array substrate 100 includes a substrate 101, and a color resist layer 110 disposed on the substrate 101, the color resist layer 110 includes a plurality of filter regions 111 with different colors, each filter region 111 includes a first filter region 112 and a second filter region 113, the first filter region 112 is embedded in the second filter region 113, the first filter region 112 has a first thickness D1 perpendicular to the array substrate 100, the second filter region 113 has a second thickness D2 perpendicular to the array substrate 100, and the first thickness D1 is smaller than the second thickness D2;
the color film substrate 200, the color film substrate 200 is opposite to the array substrate 100;
the liquid crystal layer 300 is disposed between the color film substrate 200 and the array substrate 100, and the liquid crystal layer 300 includes liquid crystal.
According to the color filter array, each light filtering area 111 in the color resistance layer 110 comprises the first light filtering area 112 and the second light filtering area 113, the first light filtering area 112 is embedded in the second light filtering area 113, the first thickness D1 of the first light filtering area 112 is smaller than the second thickness D2 of the second light filtering area 113, the light transmittance of the first light filtering area 112 is improved by utilizing the fact that the light transmittance of the color resistance layers 110 with different thicknesses is different, the technical effect that the light transmittance of the color resistance layers 110 is different is achieved, the influence of phase delay is eliminated, and the purpose of improving the display effect of the display panel 10 is achieved.
Specifically: the correspondence between the thickness of the liquid crystal layer 300 and the light transmittance is shown in the following formula:
where d is the thickness of the liquid crystal layer 300, T is the light transmittance, ψ is the azimuth angle of the liquid crystal, λ is the wavelength of the incident light, and Δn is the refractive index difference between the fast and slow axes of the uniaxial crystal.
As can be seen from the above formula: as the thickness of the liquid crystal layer 300 increases, the light transmittance increases, that is: the greater the thickness of the color resist layer 110, the smaller the light transmittance.
It should be noted that: the thickness difference between the first filter region 112 and the second filter region 113 in the color resist layer 110 is realized through a mask in an exposure stage, specifically, the exposure intensity of the color resist layer 110 is adjusted through the mask, the cross-linking reaction of different degrees of the color resist layer 110 is realized, and different thicknesses are formed after development and solidification, so that the corresponding thickness difference is obtained.
In some embodiments of the present application, the mask is a half tone (half tone) mask.
It should be understood that: according to practical requirements, the color resist layer 110 may or may not include the plurality of different color filter regions 111 with equal thickness, but each color resist in the filter regions 111 includes a first filter region 112 and a second filter region 113, and the first thickness of the first filter region 112 is smaller than the second thickness of the second filter region 113, for example, the color resist layer 110 includes a blue filter region, a red filter region and a green filter region, where the thickness of the blue filter region is greater than the thickness of the red filter region and the thickness of the green filter region, the first thickness of the first filter region 112 in the blue filter region is smaller than the second thickness of the second filter region 113, the first thickness of the first filter region 112 in the red filter region is smaller than the second thickness of the second filter region 113, and the first thickness of the first filter region 112 in the green filter region is smaller than the second thickness of the second filter region 113.
In some embodiments of the present application, the color resist layer 110 may include a red color filter layer, a green color filter layer, and a blue color filter layer. Of course, in some embodiments of the present application, the color blocking layer 110 may include a red color filter layer, a green color filter layer, a blue color filter layer, and a yellow color filter layer. In other embodiments of the present application, the color blocking layer may include a red color filter layer, a green color filter layer, a blue color filter layer, and a white color filter layer.
Further, in some embodiments of the present application, the thickness difference between the first thickness D1 and the second thickness D2 is 0.05 μm to 0.3 μm. By setting the thickness difference between the first thickness D1 and the second thickness D2 to be 0.05 μm to 0.3 μm, a phase retardation difference of 5nm to 35nm can be formed corresponding to the liquid crystal in the liquid crystal layer 300. Therefore, the light transmittance of the first filtering area 112 is significantly higher than that of the second filtering area 113, which is beneficial to the improvement of the viewing angle. Meanwhile, the designs of the different thicknesses of the color resistance layer 110 do not conflict with the liquid crystal rotation direction, and the rotation of the liquid crystal in the pixel area is facilitated due to the gradual change of the thickness of the liquid crystal layer 300.
Further, the first filtering area 112 is diamond-shaped.
Further, the second filter area 113 is rectangular, and each vertex of the first filter area 112 is connected to each side of the second filter area 113.
Further, as shown in fig. 1 and fig. 4, the array substrate 100 further includes a pixel electrode layer 102, the pixel electrode layer 102 is disposed on a side of the color resist layer 110 near the color film substrate 200, the pixel electrode layer 102 includes a plurality of pixel electrodes 120 corresponding to the plurality of filter regions 111 one by one, each pixel electrode 120 includes a trunk electrode 121 and a plurality of branch electrodes 122, the plurality of branch electrodes 122 are electrically connected to the trunk electrode 121, and the trunk electrode 121 divides the plurality of branch electrodes 122 into four areas.
By providing the trunk electrode 121 to divide the branch electrode 122 into 4 partitions, the pixel electrode 120 improves not only the color deviation in the up and down directions but also the color deviation in the left and right directions, thus eliminating the problem of the color deviation to the greatest extent.
In one embodiment of the present application, the backbone electrode 121 is in a cross shape.
Further, the plurality of branch electrodes 122 in each partition includes a plurality of first branch electrodes 1221 parallel to each other and a plurality of second branch electrodes 1222 parallel to each other, the first branch electrodes 1221 and the second branch electrodes 1222 corresponding to the first filter area 112 and the second filter area 113, respectively, each of the first branch electrodes 1221 includes at least one first sub-branch electrode, and the plurality of second branch electrodes 1222 are electrically connected to the plurality of first branch electrodes 1221 one by one;
in the present application, the first branch electrode 1221 and the second branch electrode 1222 are designed to correspond to the first filtering area 112 and the second filtering area 113, respectively, that is, the first branch electrode 1221 is embedded in the second branch electrode 1222, so that the aperture opening ratio of the pixel electrode 120 is effectively improved.
Further, the number of the first branch electrodes 1221 is greater than the number of the second branch electrodes 1222 in a unit length in the arrangement direction of the branch electrodes 122.
By setting the number of the first branch electrodes 1221 corresponding to the first filter region 112 in the unit length in the arrangement direction of the branch electrodes 122 to be larger than the number of the second branch electrodes 1222 corresponding to the second filter region 113 in the unit length in the arrangement direction of the branch electrodes 122, the order of the liquid crystal guiding at the position corresponding to the first branch electrodes 1221 in the liquid crystal layer 300 is increased or decreased, which is beneficial to forming a larger pretilt angle, and realizing the technical effect of improving the brightness of the display device 10.
Specifically: by the above arrangement, the liquid crystal at the positions corresponding to the first and second filter regions 112 and 113 can be made to form a liquid crystal rotation difference in driving, while the liquid crystal at the position of the liquid crystal layer 300 corresponding to the first filter region 112 can be made to have a larger pretilt angle so that the region threshold voltage is smaller, thus forming a difference in driving state of the liquid crystal at the positions corresponding to the first and second filter regions 112 and 113, and further improving viewing angle performance.
It should be noted that: as shown in fig. 5, the plurality of first branch electrodes 1221 are parallel to each other, and the interval P1 between every two adjacent first branch electrodes 1221 is the same. The plurality of second branch electrodes 1222 are parallel to each other, and the interval P2 between every adjacent two of the second branch electrodes 1222 is the same. The line width of each first branch electrode 1221 is W1, and the line width of each second branch electrode 1222 is W2:
2*(P1+W1)＝P2+W2
it should be understood that: the material of the pixel electrode 120 is a transparent electrode material such as Indium Tin Oxide (ITO).
Further, in at least one of the partitions, the sum of the line widths of the plurality of first branch electrodes 1221 is equal to the sum of the line widths of the plurality of second branch electrodes 1222.
Preferably, the sum of the line widths of the plurality of first branch electrodes 1221 is equal to the sum of the line widths of the plurality of second branch electrodes 1222 in any one of the partitions.
Further, as shown in fig. 4, the areas of the 4 partitions are equal.
Further, in the same partition, the inclination directions of the plurality of first branch electrodes 1221 and the plurality of second branch electrodes 1222 are identical, so as to ensure uniformity in alignment of the liquid crystal, thereby improving light transmittance; the inclination directions of the plurality of first branch electrodes 1221 and the plurality of second branch electrodes 1222 in any two adjacent partitions are different, and the inclination directions of the first branch electrodes 1221 and the second branch electrodes 1222 in any two adjacent partitions are different, so that the guiding of the liquid crystal is diversified, for example, the difference of the liquid crystal optical path differences under different angles is reduced, and the wide viewing angle display effect of the display panel 10 is effectively improved under the condition of ensuring the aperture ratio.
Further, the oblique directions of the plurality of first branch electrodes 1221 and the plurality of second branch electrodes 1222 in the 4 sections are symmetrical with respect to the trunk electrode 121. Through the arrangement, the stress of the liquid crystal molecules is uniform, and meanwhile, the manufacturing process can be simplified.
