Abstract

The invention relates to an array substrate manufacturing method, an array substrate and a liquid crystal display device and relates to the technical field of display. The manufacturing method of thefirst indium tin oxide film layer comprises steps manufacturing ofan indium tin oxide film layer and a metal protection layer in a stacked mode, manufacturing a photoresist layer on one side, deviating from the indium tin oxide film layer, of the metal protection layer, exposing by adopting a semi-gray-scale photomask process to enable the photoresist layer to form a first photoresist region and asecond photoresist region, the first photoresist region corresponding to a red pixel region and a green pixel region, the second photoresist region corresponding to a blue pixel region, and the thickness of the first photoresist region being smaller than that of the second photoresist region, etching for the first time, carrying out ashing treatment, etching for the second time, peeling off the second photoresist region, carrying out annealing treatment of the indium tin oxide film layer and the metal protective layer, etching for the third time, and finally obtaining the first indium tin oxide film layer. The array substrate manufactured by the method can reduce damage of blue light to eyes.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a manufacturing method of an array substrate, an array substrate and a liquid crystal display device. Background technique

[0002] The liquid crystal display device adopts three primary colors for imaging, and the blue light in the three primary colors is indispensable, but the blue light also has the characteristics of strong penetrating power, especially the high-frequency, high-energy blue-violet light below 450 nanometers, that is, The high-energy visible light mentioned by ophthalmologists has the ability to penetrate the cornea and lens, causing damage to the retina and macula, so the anti-blue light function of liquid crystal display devices has always been a concern of technicians.

[0003] In the prior art, the blue light cut-off is achieved by adding a plated high-low refraction matching film structure to the array substrate or color filter plate to enhance the reflec...
