Patent number: 11774654Abstract: A substrate, a mask, a display panel and a display device are provided. The substrate includes a base substrate and a color resistance layer on the base substrate. The substrate has a display area and a non-display area. The color resistance layer in the non-display area includes a weakening unit for weakening or disconnecting connection between the color resistance layer in the non-display area away from the display area and the color resistance layer in the display area. During the development and washing process of the substrate, even if the color resistance layer in the non-display area is peeled off, the color resistance layer in the display area will not be peeled off together, which helps to ensure the safety and reliability of the color resistance layer in the display area.Type: GrantFiled: October 29, 2018Date of Patent: October 3, 2023Assignees: ORDOS YUANSHENG OPTOELECTRONICS CO., LTD., BOE TECHNOLOGY GROUP CO., LTD.Inventors: Xiongwei Wang, Baojie Zhao, Jian Li, Li Wang, Xiang Hui, Yan Zhao, Qinglin Ma, Chunhong Ma
