Aiming at the liquid crystal display panel and the display device in the prior art, when the design of COA and POA is adopted, the exposure times of the color film substrate are increased rapidly due to the introduction of a large-size mask splicing product, and the production capacity of the color film substrate manufacturing process is low.
Referring to fig. 1 and fig. 2, a liquid crystal display panel provided in an embodiment of the present invention includes a color film substrate 1 and an array substrate 2 that are disposed opposite to each other, and a liquid crystal layer 3 disposed between the color film substrate 1 and the array substrate 2.
The color film substrate 1 includes a first substrate 11, where the first substrate 11 includes a plurality of sub-pixel regions 111 and a light-shielding region 112 located between two adjacent sub-pixel regions 111, and the sub-pixel regions 111 are provided with a plurality of color resistance units, for example, including a red color resistance unit R, a green color resistance unit G, and a blue color resistance unit B, so as to implement color display of the liquid crystal display panel; the light-shielding region 112 is disposed corresponding to the opaque metal traces on the array substrate 2, and is used to form a black matrix to shield the opaque metal traces, where the opaque metal traces include scan lines and TFT devices. In the embodiment of the invention, the light-shielding region 112 may be a long stripe shape to correspond to the scan line.
The light-shielding region 112 is provided with a first color resist portion 13 and a second color resist portion 14 formed by stacking double-layer color resist blocks, black photoresist layers 15 are arranged on the first color resist portion 13 and the second color resist portion 14, the first color resist portion 13 and the black photoresist layers 15 are stacked to form a main spacer 151, and the second color resist portion 14 and the black photoresist layers 15 are stacked to form an auxiliary spacer 152; a certain step difference needs to be formed between the main spacers 151 and the auxiliary spacers 152, so that the main spacers 151 play a main supporting role for the color filter substrate 1 and the array substrate 2, and when the liquid crystal display panel is squeezed by an external force, the auxiliary spacers 152 play an auxiliary supporting role for the color filter substrate 1 and the array substrate 2, so that the main spacers 151 and the auxiliary spacers 152 are combined to play a multi-stage buffering role, and various Mura or bad effects are prevented.
The key dimension of the orthographic projection of the second color resist part 14 on the first substrate 11 is smaller than the key dimension of the orthographic projection of the first color resist part 13 on the first substrate 11, it should be noted that, in the embodiment of the present invention, the key dimension refers to that the linearity of a specific pattern in a certain characteristic direction is sufficiently small, it can be understood that the key dimension of the orthographic projection of the first color resist part 13 on the first substrate 11 is the minimum side length of the orthographic projection pattern, and the key dimension of the orthographic projection of the second color resist part 14 on the first substrate 11 is the minimum side length of the orthographic projection pattern; that is, the minimum side length of the orthogonal projection pattern of the second color resist 14 on the first substrate 11 is smaller than the minimum side length of the orthogonal projection pattern of the first color resist 13 on the first substrate 11.
Specifically, the first color resist portion 13 includes a first color resist block 131 and a second color resist block 132 which are stacked, the second color resist portion 14 includes a third color resist block 141 and a fourth color resist block 142 which are stacked, and the first color resist block 131 and the third color resist block 141 are disposed on the same layer on the side of the first substrate 11 facing the array substrate 2; in the embodiment of the present invention, the first color blocking block 131 and the third color blocking block 141 are red color blocking blocks, and the second color blocking block 132 and the fourth color blocking block 142 are blue color blocking blocks. Of course, the first color blocking block 131 and the third color blocking block 141, and the second color blocking block 132 and the fourth color blocking block 142 may also be color blocking blocks of other colors, which should not be limited in the embodiments of the present invention.
Accordingly, it is required to ensure that the key dimension of the orthographic projection of the third color blocking block 141 on the first substrate 11 is smaller than the key dimension of the orthographic projection of the first color blocking block 131 on the first substrate 11. It can be understood that the black photoresist layer 15 is a liquid with certain viscosity and fluidity, and has a certain leveling property, when the black photoresist layer 15 is coated on the first color resist portion 13 and the second color resist portion 14, it will level around the second color resist block 132 and the fourth color resist block 142, respectively. The leveling effect of the black photoresist layer 15 depends on the critical dimensions of the first color resist block 131 and the third color resist block 141, that is, the better the leveling effect of the black photoresist layer 15 on the color resist block with the smaller critical dimension, and because the critical dimension of the orthographic projection of the third color resist block 141 on the first substrate 11 is smaller than the critical dimension of the orthographic projection of the first color resist block 131 on the first substrate 11, the height of the main spacer column 151 formed by stacking in a direction perpendicular to the first substrate 11 is greater than the height of the auxiliary spacer column 152 in a direction perpendicular to the first substrate 11.
Specifically, the key dimension of the orthographic projection of the third color bump resist block 141 on the first substrate 11 is smaller than 1/3-1/2 of the key dimension of the orthographic projection of the first color bump resist block 131 on the first substrate 11, at this time, the step difference between the main spacer 151 and the auxiliary spacer 152 can be adjusted to meet the requirement, and it should be noted that, since the manufacturing process and the material are key factors affecting the leveling property, the specific values of the key dimensions of the orthographic projection of the first color bump resist block 131 and the third color bump resist block 141 on the first substrate 11 need to be determined according to the specific actual manufacturing process and material.
It can be understood that, in the present application, the main spacer 151 and the auxiliary spacer 152 are formed by leveling the black photoresist layer 15 with a double-layer color barrier pad, and there is no need to increase the leveling of the organic flat layer to improve the step, so as to effectively reduce the manufacturing process, increase the productivity, and reduce the cost.
Alternatively, the shape of the orthographic projection of the first color blocking block 131 and the second color blocking block 132 on the first substrate 11 may be any shape. Preferably, the shape of the orthographic projection of the first color blocking block 131 and the second color blocking block 132 on the first substrate 11 is a square, the film thickness of the first color blocking block 131 and the second color blocking block 132 can be maximized by adopting a square design, and generally, the key size of the orthographic projection of the first color blocking block 131 on the first substrate 11 is greater than 25um by 25 um.
Further, a key dimension of an orthographic projection of the third color blocking block 141 on the first substrate 11 is smaller than 1/3-1/2 of a key dimension of an orthographic projection of the first color blocking block 131 on the first substrate 11, an area ratio of a bottom side of one side of the third color blocking block 141 close to the first substrate 11 is ensured, a shape of the orthographic projection of the third color blocking block 141 on the first substrate 11 is any one of an "L" shape, a "Z" shape, an "S" shape and an "I" shape, and a shape of the orthographic projection of the fourth color blocking block 142 on the first substrate 11 is any one of an "L" shape, a "Z" shape, an "S" shape and an "I" shape, but the embodiment of the present invention is not limited thereto. In fig. 2, the third color blocking block 141 and the fourth color blocking block 142 are L-shaped.
Referring to fig. 3, generally, the volume of the fourth color blocking block 142 is smaller than that of the third color blocking block 141, and therefore, in order to prevent the critical dimension of the fourth color blocking block 142 from being too small to cause the fourth color blocking block 142 to fall off (peeling) from the third color blocking block 141, the critical dimension of the orthographic projection of the fourth color blocking block 142 on the first substrate 11 is larger than the critical dimension of the orthographic projection of the third color blocking block 141 on the first substrate 11.
Specifically, the key dimension of the orthographic projection of the third color blocking block 141 on the first substrate 11 is smaller than 15um, the key dimension of the orthographic projection of the fourth color blocking block 142 on the first substrate 11 is larger than 15um,

In the embodiment of the present invention, the main spacers 151 and the auxiliary spacers 152 correspond to one of the sub-pixel regions 111, that is, the first color resists 13 and the second color resists 14 correspond to one of the sub-pixel regions 111 and are uniformly arranged according to a certain arrangement rule, so that the formed main spacers 151 and the formed auxiliary spacers 152 have a better supporting effect on the liquid crystal display panel, for example, the main spacers 151 and the auxiliary spacers 152 are uniformly arranged according to an arrangement rule with a quantity ratio of 1:23, and the first color resists 13 and the second color resists 14 are uniformly arranged according to an arrangement rule with a quantity ratio of 1: 23.
