Publication number: 20220376153Abstract: A display device includes an active pattern, a gate electrode, a gate signal line, and a light emitting diode. The active pattern is disposed on a substrate. The gate electrode is disposed on the active pattern and overlaps the active pattern in a plan view. The gate electrode defines a channel area in an area overlapping the active pattern in a plan view. The gate signal line is disposed on the gate electrode. The gate signal line overlaps the channel area in a plan view. The gate signal line transmits a gate signal to the gate electrode. The light emitting diode is disposed on the gate signal line.Type: ApplicationFiled: March 18, 2022Publication date: November 24, 2022Applicant: Samsung Display Co., LTD.Inventors: Soohong CHEON, Hyungjin SONG, Seongyoung LEE

Patent number: 11176856Abstract: A display device and a method of inspecting signal lines of the display device facilitating inspection of a large number of signal lines are disclosed. According to one embodiment, the display device includes: a substrate; a first signal line disposed in a display area of the substrate; and a first inspection line disposed in a non-display area of the substrate and connected to the first signal line. The first inspection line includes: a first line connected to the first signal line; a second line disposed on a layer substantially the same as a layer on which the first line is disposed, the second line spaced apart from the first line; and a third line disposed on a layer different from the layer on which the first line and the second line are disposed with an insulating layer interposed therebetween, the third line overlapping at least a portion of the first line and a portion of the second line.Type: GrantFiled: February 12, 2019Date of Patent: November 16, 2021Inventors: Donghee Shin, Hyungjin Song, Byoungsun Na, Yoomi Ra, Soohong Cheon
