Publication number: 20230061983Abstract: A display apparatus may include at least one switching thin film transistor and a driving thin film transistor, which are disposed on a device substrate. The driving thin film transistor may include a driving semiconductor pattern made of an oxide semiconductor. A light-blocking pattern may be disposed between the device substrate and the driving semiconductor pattern. The light-blocking pattern may be disposed close to the driving semiconductor pattern. Thus, in the display apparatus, a current variation value according to a voltage applied to the driving gate electrode of the driving thin film transistor may be reduced, without changing the characteristics of the switching thin film transistor. Thereby, in the display apparatus, the occurrence of a spot in low grayscale may be prevented.Type: ApplicationFiled: August 10, 2022Publication date: March 2, 2023Applicant: LG Display Co., Ltd.Inventors: Duk Young JEONG, Ki Sul CHO, Jeong Yeop LEE, Jang Dae KIM, Min Cheol KIM
