Color filter substrate, liquid crystal box and manufacturing method of color filter substrate and liquid crystal box

Abstract

The invention discloses a color filter substrate, a liquid crystal box and a manufacturing method of the color filter substrate and the liquid crystal box. A red area, a green area and a blue area; a black matrix; a measurement area is arranged in a non-display area of the color filter substrate, the measurement area comprises one or more special test pattern combinations, the special test pattern combinations are provided with retaining walls around the test pattern combinations, and the retaining walls are suitable for blocking or inhibiting spacer column materials on the edges of the test pattern combinations surrounded by the retaining walls from flowing to the periphery. According to the method, the height uniformity of the top end of each spacer column can be evaluated by adopting a conventional spacer column mask test pattern combination, namely, the column height uniformity under the condition of different spacer column sizes can be detected / evaluated at the same time; meanwhile, the negative influence on the detection / evaluation accuracy caused by the height variation of the spacer columns at the edge of the spacer column mask test pattern due to the material flowability is avoided, and the accuracy of detecting / evaluating the height uniformity of the top ends of the spacer columns in the liquid crystal box is improved.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a color filter substrate, a liquid crystal cell and a manufacturing method thereof. Background technique [0002] Liquid Crystal Display (LCD) is a commonly used flat-panel display. Under the action of an electric field, the arrangement direction of liquid crystal molecules is changed to change the light transmittance of the external light source, complete the electrical-optical conversion, and then reuse it. Different excitation of R, G, B (red, green, blue) three primary color signals, through the R, G, B three primary color filter film, complete the color reproduction in time domain and space domain. [0003] Liquid crystal displays have many advantages such as low power consumption, small size, and low radiation. They have been widely used in daily life and in all walks of life. For example, they are often used in the screen display of TV sets or computers. ...

Problems solved by technology

[0006] In the prior art, some solutions adopt the method of setting a measurement area in the non-display area of ​​the color filter substrate to detect / evaluate the uniformity of the top height of the spacer column, and the measurement area includes one or more test pattern combinations, but the above-mentioned solution There is a defect that the accuracy is not high, and the height of the spacer column in the measured measurement area often cannot accurately reflect the actual height of the spacer column in the display area; another part of the scheme cannot simultaneously calculate the column height under different spacer column sizes (PS Size) The uniformity is tested / evaluated, that is, the spacer columns with different spacer column sizes need to be tested / evaluated separately, which is inefficient
