Abstract

The disclosure provides a display substrate, a display device and a manufacturing method thereof, belonging to the field of display technology. The display substrate includes a substrate; and a blue light suppression layer disposed on the substrate, wherein the blue light suppression layer attenuates a portion of blue light emitted by a light source. In the present disclosure, by forming the blue light suppression layer in the manufacturing process of the existing display device, there is no need to greatly modify the manufacturing process, thereby solving the problem of blue light damage in the display device in a simple and cost-effective manner.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a display substrate, a display device and a manufacturing method thereof. Background technique [0002] The white light generated by LED (light emitting diode, light emitting diode) is mainly realized by combining blue light chip with yellow phosphor powder. Blue light refers to visible light having a wavelength of approximately 400-500 nm. The wavelength and intensity of the blue light in the white light produced by the LED is concentrated around 460nm, such as 440-470nm, which is a great burden on the eyes. When exposed to blue light for a long time, human eyes may suffer various damages. The International Commission on Illumination (CIE) promulgated the CIE S009:2002 "PHOTOBIOLOGICAL SAFETY OF LAMPS AND LAMP SYSTEMS (Photobiological Safety of Lamps and Lamp Systems)" standard in 2002, and began to mention blue light-related hazards. The International Electrote...
