Abstract: A display device includes a first layer disposed on a base layer and including a first gate electrode, a first gate insulating layer, and an active layer, and a second layer disposed on the first layer and including a second gate electrode, a second gate insulating layer, and the active layer. The first layer and the second layer share the active layer. The first gate insulating layer has a first dielectric constant, and the second gate insulating layer has a second dielectric constant. The first dielectric constant and the second dielectric constant are different from each other.

Abstract: A method includes: forming a MOSFET layer on a semiconductor wafer substrate, the MOSFET layer including: pixel driver circuits; and a display driver circuit; forming at least one line layer on the MOSFET layer; applying a first supply voltage to a first supply voltage line through a first supply voltage pad; connecting data fan-out lines connected to the pixel driver circuits with a first test line by controlling a test switching circuit in the MOSFET layer; measuring an electrical signal generated from each of the pixel driver circuits through a first test pad connected to the first test line; determining whether each of the pixel driver circuits is defective or not based on the measured electrical signal; and forming a light-emitting element layer including light-emitting elements on the at least one line layer when that the pixel driver circuits are determined to be not defective.
