As shown in fig. 3 and 4, the lcd panel includes a plurality of pixel regions 10, each pixel region 10 is arranged in an array in the lcd panel, in each pixel region 10, the black matrix 202 includes three independent opening regions, which are a first opening region 11, a second opening region 12 and a third opening region 13, respectively, the color barrier layers include three independent color blocks, which are a first color block 21 covering at least the first opening region 11, a second color block 22 covering at least the second opening region 12 and a third color block 23 covering at least the third opening region 13, respectively, each color block may be disposed only in the corresponding opening region, or may exceed the range of the opening region, but does not contact with each other, and there is a gap. The first color block 21, the second color block 22 and the third color block 23 have different colors, and the three are one of a red color block, a green color block and a blue color block, i.e., any one of the first color block 21, the second color block 22 and the third color block 23 can be one of red, green or blue, and the other two are the rest two colors. When preparing the black matrix and the color resistance layer, the whole layer of the black matrix is prepared, then the opening areas are formed by patterning, and finally the color resistance block is formed in the area where each opening area is located by a proximity exposure machine.
The liquid crystal layer 30 is filled between the array substrate and the color film substrate, and a retaining wall 40 is further disposed on one side of the color film substrate facing the array substrate for supporting. When the display is needed, the pixel electrode and the common electrode are electrified to form an electric field to deflect liquid crystal molecules, and the resistance blocks of each color display different gray scales according to different deflection degrees.
For the three color blocks formed in each pixel area, the first color block 21 and the second color block 22 are arranged along a first direction, and an overlapping area exists between a first orthographic projection of the first color block 21 and the second color block 22 along a second direction, which is perpendicular to the first direction, and a second orthographic projection of the third color block 23 along the second direction. As shown in fig. 5 to 7, the first color block 21 and the second color block 22 are arranged along the first direction S1, the second direction S2 is perpendicular to the first direction S1, a virtual line parallel to the first direction S1 is provided, on the virtual line, the first color block 21 and the second color block 22 form a first front projection along the second direction S2, the first front projection a1-a2 formed by the first color block 21 along the second direction S2 and the front projection A3-a4 formed by the second color block 22 along the second direction S2 respectively are included, the third color block 23 forms a second front projection B1-B2 along the second direction S2, and an overlapping region exists between the second front projection and the first front projection.
The overlapping area between the second front projection and the first front projection may include various situations, specifically, as shown in fig. 5, there is an overlapping area a1-B2 between the second front projection B1-B2 and the front projection a1-a2 of the first color block 21, there is no overlapping area with the front projection A3-a4 of the second color block 22, and a1-B1 is a portion beyond the range of a1-a2, in which case the second front projection of the third color block 23 only overlaps the first front projection of the first color block 21, and the overlap is a partial overlap. As shown in FIG. 6, the second orthographic projection B1-B2 has an overlapping region A1-A2 with the orthographic projection A1-A2 of the first color block 21, and has no overlapping region with the orthographic projection A3-A4 of the second color block 22, in which case the second orthographic projection of the third color block 23 only overlaps with the first orthographic projection of the first color block 21, and the overlap is complete. As shown in FIG. 7, the second orthographic projection B1-B2 has an overlapping region B1-A2 with the orthographic projection A1-A2 of the first color block 21 and an overlapping region A3-B2 with the orthographic projection A3-A4 of the second color block 22, in which case the second orthographic projection of the third color block 23 simultaneously overlaps both the first orthographic projection of the first color block 21 and the first orthographic projection of the second color block 22, and completely overlaps the first color block 21 and partially overlaps the second color block 22.
It should be noted that, the above embodiment only shows some overlapping manners of the second forward projection and the first forward projection, but not limited to this, a person skilled in the art may select whether the second forward projection overlaps with both the two first forward projections or only one of the two first forward projections as needed, and may also select to partially overlap or completely overlap with each of the first forward projections as needed.
As shown in fig. 1, in the prior art, the first color block 21, the second color block 22 and the third color block 23 in each pixel area 10 are all strip-shaped and arranged along a first direction, and the three blocks form a linear arrangement structure. The minimum width of the color block which can be manufactured by the proximity exposure machine on the current market is 7um due to the limitation of the manufacturing process of the color block material and the proximity exposure machine, on the premise, if the liquid crystal display panel is required to reach 1500PPI, the width of each color block can be met only when the width of each color block reaches 5.6um according to the arrangement mode in figure 1, and obviously, the current proximity exposure machine cannot meet the manufacturing requirement, so that the liquid crystal display panel with 1500PPI cannot be manufactured, and the high PPI requirement of the liquid crystal display panel in VR and AR scenes cannot be met. In this application, PPI refers to the number of pixels per inch possessed by the panel, and the higher the value of PPI, the more the number of pixels per equivalent area, and correspondingly the smaller the size of pixels.
In the embodiment of the present application, as shown in fig. 5 to 7, since there is an overlapping region between the first orthographic projection and the second orthographic projection and the color blocks are independent from each other, it means that there is no possibility of the third color block 23 existing in the first direction S1 between the first color block 21 and the second color block 22, the left side of the first color block 21, and the right side of the second color block 22, and the third color block 23 can only be arranged in a certain range of the upper side or the lower side of the first color block 21 and the second color block 22, and at this time, the three color blocks do not form a structure linearly arranged along the first direction S1, but are staggered from each other to form an island structure.
For the straight line arrangement in fig. 1, it is necessary to accommodate the widths of three color blocks and the widths of two gaps in the first direction, and for the arrangement in fig. 5 to 7, it is only necessary to accommodate the width of one gap and the width of no more than three color blocks in the first direction, so that under the same total width, the arrangement in this application can make the widths of the first color block 21, the second color block 22 and the third color block 23 all be set larger, and can make the third color block 23 only partially exceed the left side of the first color block 21 or the right side of the second color block 22, or completely exceed the left side of the first color block 21 and the right side of the second color block 22, until the total width of the color blocks in the first direction can satisfy the limit production size of the current proximity exposure machine, and further can make a higher PPI, meet the high PPI requirement of the liquid crystal display panel
For the arrangement shown in fig. 5, the third color block 23 may partially exceed the left side of the first color block 21 or the right side of the second color block 22, for example, exceed the left side of the first color block 21 by 50%, and at this time, only 2.5 color blocks need to be accommodated, and compared with the width of 3 color blocks in the prior art, the width of the present application may be set to be larger to meet the requirement of the manufacturing process of the proximity exposure machine.
For the arrangement shown in fig. 6 and 7, since the second orthographic projection falls within the range of the first orthographic projection, the widths of two color blocks in the first direction are only required to be satisfied, and at this time, the gap between the first opening region 11 and the second opening region 12 on the corresponding black matrix is set to be 2.5um, so that the widths of the first color block 21 and the second color block 22 can be further increased to 8um or more, and if the size is 8um 9.2um, it is easier to satisfy the requirement of obtaining high PPI by the preparation process.
In one embodiment, the first color block 21, the second color block 22 and the third color block 23 are respectively one of a red color block, a green color block and a blue color block, and the area of the opening area corresponding to the green color block is larger than the area of the opening area corresponding to the red color block and the blue color block. Because the transmissivity of the green color block is greater than the transmissivity of the color blocks of other two colors, the area of the green color block can be increased, and the transmissivity of the whole panel is improved.
In one embodiment, the opening area corresponding to the green color block has a first area, the opening area corresponding to the blue sub-pixel has a second area, the opening area corresponding to the red sub-pixel has a third area, and the ratio of the first area, the second area and the third area is 1.2:1:1, which is better in transmittance.
In one embodiment, the liquid crystal display panel further comprises a light condensing member disposed on a side of the color resist layer close to the liquid crystal layer and/or a side far from the liquid crystal layer, the light condensing member being configured to condense the outgoing light rays in each of the opening regions. As shown in fig. 2, the light-gathering member 50 is disposed on one side of the color resist layer close to the liquid crystal layer 30, the light source of the liquid crystal display panel is provided by the backlight module, and the light emitted from the backlight module propagates upward and is emitted through the color resist blocks in each opening region to form emergent light. Because the luminous light of backlight unit has certain divergence, and the light when passing each opening district is not many for the light efficiency is not high, through set up spotlight component 50 in one side that the colour resistance layer is close to liquid crystal layer 30, can converge earlier light, then pass the colour resistance piece in the opening district again, thereby reach the effect that promotes the light efficiency. As shown in fig. 8, the light condensing member 50 is disposed on a side of the color resist layer away from the liquid crystal layer 30, that is, between the second substrate 201 and the color resist layer, at this time, since the light emitted by the backlight module has a certain divergence and still has a divergence after passing through each opening area, at this time, the light condensing member 50 can condense the part of the light and then emit the light out of the liquid crystal display panel, and the light effect is also improved to a certain extent.
