Embodiment 1

[0026] This embodiment provides a black matrix structure, which includes an array of pixel units 10 spliced ​​by a plurality of sub-black matrices 100, each pixel unit 10 includes a pixel opening area 11 and a black matrix pattern area 12 surrounding the pixel opening area 11, and The splicing line 20 formed by splicing two adjacent sub-black matrices 100 is a curve; wherein, the splicing line 20 includes at least one curved unit, and the maximum width of the curved unit in the row direction is not less than the width of the pixel unit 10 , the maximum height in the column direction is greater than the height of the black matrix pattern area 12 between the pixel opening areas 11 in two adjacent rows.

[0027] In the black matrix structure of this embodiment, the splicing line 20 formed by splicing the two sub-black matrices 100 is a curved line, so that poor display caused by the concentrating of the splicing lines 20 on a straight line in the prior art can be avoided. Specifi...

Embodiment 2

[0033] This embodiment provides a mask for forming the pattern of the sub-black matrix 100 in the first embodiment.

[0034] Such as Figure 5 As shown, as a preferred structure of this embodiment, the mask includes a non-transmissive area 32 corresponding to the pixel opening area 11 in the sub-black matrix 100 and an opaque area 32 corresponding to the black matrix pattern area 12. Light-transmitting area 31 . At this time, it is required to coat a negative photoresist on the substrate forming the black matrix material film, and use the mask to expose, so that the photoresist located in the black matrix pattern area 12 is denatured; Removing the photoresist at position 11; removing the black matrix material film at position 11 of the pixel opening area; finally stripping off the remaining photoresist to form the pattern of the sub-black matrix 100 in the first embodiment.

[0035] Such as Figure 6 As shown, as another preferred structure of this embodiment, the mask incl...

Embodiment 3

[0037] This embodiment provides a color filter substrate, which includes the black matrix structure in Embodiment 1, so the performance of the color filter substrate in this embodiment is better.

[0038] Of course, the color filter substrate also includes known structures such as color filters, which will not be described here.

Abstract

The invention provides a black matrix structure, a mask plate, a color membrane substrate and a display device, belongs to the technical field of displaying, and can solve the problem of poor displaying caused by errors in the spliced position of the conventional black matrix structure. The black matrix structure comprises a pixel unit array formed by splicing a plurality of sub black matrixes, wherein each pixel unit comprises a pixel opening region and a black matrix pattern region which surrounds the pixel opening region, and a spliced line formed by splicing every two adjacent sub black matrixes is a curved line; each spliced line comprises at least one bent unit, the maximum width of each bent unit in the row direction is not smaller than the width of the pixel unit, and the maximum height of the bent unit in the column direction is greater than the height of the black matrix pattern region between every two adjacent rows of pixel opening regions. The black matrix and the mask plate are especially suitable for the large-sized display devices.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a black matrix structure, a mask plate, a color filter substrate and a display device. Background technique [0002] Currently, Liquid Crystal Display (LCD for short) has become a mainstream product in the market due to its excellent performance and mature technology. With the development of display technology, high transmittance, large size, low power consumption, and low cost have become the development direction of the display field in the future. [0003] In the process of preparing the color filter substrate of the existing ultra-large-sized liquid crystal display, due to the large size of the substrate, it is impossible to form the entire basic pattern with a single exposure, so a splicing method has to be used to realize the exposure process of the entire substrate. In the traditional splicing exposure method, because the splicing process on both sides of the...
