Abstract

The invention relates to a color filter substrate and a test method. The color filter substrate comprises a scale structure located on a non-display area of a light-transmissive substrate, wherein thescale structure comprises a second shading pattern layer having a second opening therein, a second filtering layer group, the second filtering layer group comprises a first non-display light filtering layer, the first non-display light filtering layer and the first display light filtering layer are the same in color, the first non-display light filtering layer is located in the second opening, afirst gap area is formed between an edge of the first non-display light filtering layer and the second shading pattern layer, and the first gap area surrounds the first non-display light filtering layer. The color filter substrate is advantaged in that performance of a color filter substrate is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a color filter substrate and a testing method. Background technique [0002] In recent years, with the development of the information and communication field, there is an increasing demand for various types of display devices. Currently, mainstream display devices include liquid crystal displays, plasma displays, electroluminescent displays, and vacuum fluorescent displays. Due to the advantages of lightness, thinness, small size, low power consumption, and low radiation, liquid crystal displays are widely used in various data processing equipment, such as TVs, notebooks, mobile phones, personal digital assistants, etc. [0003] The liquid crystal display mainly includes: a TFT array substrate, a color filter substrate, and a liquid crystal layer between the TFT array substrate and the color filter substrate. The electrodes on the TFT array substrate and the color filter s...
