Patent number: 10444581Abstract: Provided are a COA array substrate and a display device. The array substrate is provided with a base layer, a metal layer, and a color resist layer from bottom to top. The array substrate is further provided with contact holes passing through the color resist layer and in contact with the metal layer, and the contact holes are arranged so that the alignment film droplets can be distributed when the alignment film droplets drop right onto the contact holes. Air bubbles as in the prior art are thus avoided, thereby preventing a cell gap due to accumulation of an alignment film from becoming larger. Thus, a luminance difference is avoided and the quality of the product is improved without upgrading the existing equipment. The brightness uniformity of the display device is improved by using the array substrate.Type: GrantFiled: April 10, 2017Date of Patent: October 15, 2019Assignee: SHENZHEN CHINA STAR OPTOELECTRONICS TECHNOLOGY CO., LTD.Inventors: Li Chai, Maolin Wang, Xing Lei, Chengcai Dong
