Publication number: 20210389623Abstract: A display panel and a manufacturing method thereof are provided. The display panel includes: an array substrate with a first protrusion defined thereon; a color filter substrate disposed opposite to the array substrate; a supporting structure, wherein an end of the supporting structure is connected to a lateral side of the color filter substrate, another end of the supporting structure is connected to a lateral side of the array substrate, and the first protrusion is embedded into the supporting structure. The first protrusion is formed on a side of the array substrate near the color filter substrate. Therefore, when the supporting structure of the color filter substrate is aligned and attached to the array substrate, the first protrusion can be embedded into the supporting structure, thereby preventing the supporting structure from being moved. Thus, risk of alignment error is reduced, and abnormality of the display panel is prevented.Type: ApplicationFiled: September 14, 2020Publication date: December 16, 2021Applicant: Wuhan China Star Optoelectronics Technology Co., Ltd.Inventors: Fei AI, Dewei SONG
