Problems solved by technology

That is to say, figure 2 The organic resin layer 120 corresponding to area A and area D in the center is rubbed normally, the organic resin layer 120 corresponding to area C is not rubbed or the degree of rubbing is relatively shallow, the alignment film in area C has insufficient alignment force for liquid crystal, and the dark state effect of the screen is not good , affect the picture quality of the final product, which may seriously cause bright spots near the columnar spacers in the pixel display area or poor light leakage of the display panel
[0008] To sum up, the arrangement of the columnar spacers in the prior art leads to poor quality of the alignment film, which will affect the image display quality in severe cases

Embodiment 1

[0040] see Figure 4 The figure of the cross-section of the columnar spacer 2 is fan-shaped, and the front end part of the figure along the set first direction is the part of the fan shape close to the center o of the circle. That is, the fan-shaped figure close to the circle center o is the figure of the front end part along the first direction, and the figure far away from the circle center o, for example, the figure corresponding to the arc is the figure of the rear end part of the columnar spacer along the first direction.

[0041] That is to say, the shape of the columnar spacer 2 along the first direction has a tapered front end portion and a progressively increasing shape at the rear end portion.

[0042] Specifically, see Figure 4 , there are two first intersection points between the straight line extending along the second direction perpendicular to the first direction and the outer contour of the front end portion of the figure along the first direction, such as ...

Embodiment 2

[0045] see Figure 5 The figure of the cross section of the columnar spacer 2 is a triangle, any side of the triangle is perpendicular to the first direction, and the figures corresponding to the other two sides are the front end of the columnar spacer along the first direction.

[0046] The rear end portion of the pattern of the columnar spacer 2 along the first direction also satisfies that the distance between two boundary points of the pattern gradually becomes smaller in the second direction perpendicular to the first direction. That is to say, there are two first intersection points a and a between the straight line extending in the second direction perpendicular to the first direction and the outer contour of the front end portion of the figure along the first direction. ', the distance d between the two first intersection points a and a' gradually decreases as the vehicle travels along the first direction. There are two second intersection points b and b' between the ...

Embodiment 3

[0049] see Figure 6 , The figure of the cross-section of the columnar spacer 2 is trapezoidal, the figure is trapezoidal, and the extension direction of the bottom of the trapezoidal shape is perpendicular to the first direction. That is, the extending direction of the two parallel sides of the trapezoid is consistent with the second direction and perpendicular to the first direction. The bottom side is the longer side of the two sides parallel to each other.

[0050] For the columnar spacers provided in the second and third embodiments above, the shape of the rear end portion along the first direction is not limited.

[0051] In order to further reduce the hindering effect of the friction wool on the friction cloth and the spacer, further, the cross-sectional pattern of the columnar spacer provided by the embodiment of the present invention has a gradually increasing shape along the rear end portion of the first direction.

[0052] That is to say, there are two second inte...

Abstract

The invention discloses a columnar insulation mat and a display substrate to improve the quality of an alignment layer and the display quality of an image. The cross section of the columnar insulation mat is a closed shape, and the front end part of the shape is in a gradually shrinking shape in the set first direction.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a column spacer and a display substrate. Background technique [0002] In the field of liquid crystal display technology, columnar spacers for supporting the color filter substrate and the array substrate are usually provided in the area corresponding to the black matrix on the display substrate (such as a color filter substrate or an array substrate); as the resolution of display products continues to increase, As it increases, more and more pixels are formed per unit area. In order to ensure a higher aperture ratio of each pixel, the size of the black matrix is ​​getting smaller and smaller. This requires the structure of each pixel display area except the black matrix, such as the structure of the alignment film, to be very precise. [0003] The alignment process of the alignment film is achieved by rubbing the organic resin layer to be rubbed with a rubbing c...
