Embodiment Construction

[0036] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0037] Such as figure 2 As shown, the embodiment of the present invention provides a color filter substrate, including:

[0038] Substrate 1;

[0039] A black matrix 2 formed on the substrate 1;

[0040] For the columnar spacers 3 formed above the black matrix 2 , the cross-sectional area of ​​both ends (referring to the end connected to the black matrix 2 and the floating end) is smaller than the cross-sectional area of ​​the part between the two ends.

[0041] The longitudinal section of the columnar spacer 3 can be hexagonal, fish-maw or other shapes with a wide middle and narrow ends. When the cross-sectional area of ​​one end of the columnar spacer 3 connected to the black matrix 2 is small, the columnar spacer 3 is not easy t...

Abstract

Provided are a color film substrate, manufacturing method and display device, the color film substrate comprising a substrate (1), a black matrix (2) formed on the substrate (1), and a columnar spacer (3) formed above the black matrix (2); the cross section area at the two ends of the columnar spacer (3) is smaller than that of the part between the two ends. In the color film substrate, the columnar spacer (3) is unlikely to break, and has a strong supporting capability, thus ensuring the thickness of a box.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a color filter substrate, a manufacturing method and a display device. Background technique [0002] With the cost reduction of thin film transistor liquid crystal display and the improvement of manufacturing process, thin film transistor liquid crystal display has become the mainstream product in the field of flat panel display. [0003] A thin film transistor liquid crystal display includes an array substrate, a color filter substrate and a liquid crystal material filled between them. Wherein, the color filter substrate usually includes a substrate, sub-pixels with colors (such as sub-pixels of three primary colors), a black matrix formed in the gap between the sub-pixels, and a columnar spacer formed above the black matrix. Such as figure 1 As shown, when the distance d between the column spacer a and the sub-pixel b is small, the rubbing of the alignment layer correspondin...
