Problems solved by technology

[0008] However, when the color filter unit is manufactured, the thickness of different positions fluctuates greatly, which will cause the height of the spacer column 115 to be uneven. The height refers to the distance between the top of the spacer column 115 and the surface of the transparent substrate 110
The uneven height of the spacer columns 115 will affect the performance of the display panel behind the box
Even in wide viewing angle IPS technology products, a flat layer is set on the color filter unit to buffer the above-mentioned ups and downs, however, it cannot meet the technical needs

Abstract

A display panel, a color filter substrate, and a method for manufacturing a color filter substrate. For a color filter substrate, a notch is provided in a part of a column of color filter units, and the color filter units of an adjacent column are arranged at the notch to match the color filter unit. The protruding part with the matching shape and size of the notch, and a spacer column is arranged on the protruding part. Compared with the color filter substrate in the prior art, where the spacer column is set above the superposition of two columns of color filter units, the spacer column in the present invention is located on a single color filter unit, and the thickness control of a single color filter unit is compared to that of two columns of filter units. The thickness of the superimposed part of the color filter units is easy to control, so the height uniformity of the spacer columns can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a color filter substrate and a manufacturing method of the color filter substrate. Background technique [0002] figure 1 It is a schematic cross-sectional structure diagram of a display panel in the prior art. refer to figure 1 As shown, the display panel includes: a color filter substrate 11 and a TFT substrate 12 . A liquid crystal material (not shown) is filled between the color filter substrate 11 and the TFT substrate 12 . [0003] Taking the liquid crystal drive mode as TN (Twisted Nematic) as an example, the color filter substrate 11 includes: a light-transmitting substrate 110, the material of which can be glass, for example; light-shielding strips arranged on the surface of the light-transmitting substrate 110, and the light-shielding strips are arranged in rows and columns Constitute the black matrix 111, the area not covered by the black matrix 1...
