Abstract

The embodiment of the invention provides a COA substrate, a manufacturing method thereof and a display device, and relates to the field of the display technology. The problem that in an existing COA substrate, a black matrix cannot be aligned with a pattern of a layer structure in front of the black matrix when the black matrix is formed is solved. The display quality of the display device is improved, and the produced display device is prevented from becoming a defective good. The COA substrate comprises the black matrix made of materials through which infrared light can transmit. An aligning light source for aligning the black matrix with the pattern of the layer structure in front of the black matrix is the infrared light. The COA substrate is applied to the manufacturing technology of the display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a COA substrate, a manufacturing method thereof, and a display device. Background technique [0002] Display devices such as Liquid Crystal Display (LCD for short) and Organic electroluminescent device (OLED for short) have become necessities in people's lives. With the improvement of people's needs, in order to improve the display quality of display devices To avoid the deviation of the array substrate and the color filter substrate when the box is aligned, affecting the aperture ratio of the display device and the problem of light leakage, the integrated technology (Color Filter on Array, COA for short) that integrates the color filter and the array substrate is born. COA technology is to arrange black matrix and color filter on the array substrate. [0003] The existing black matrix is ​​generally made of resin coated with carbon black particles. Since the carbon black parti...
