US 2021/0343780 A1 · ARRAY SUBSTRATE, METHOD OF MANUFACTURING THE SAME, AND DISPLAY DEVICE

Abstract

An array substrate includes a base substrate, a thin film transistor on the base substrate, including a gate electrode connected to a gate line, an active layer, a gate insulating layer insulating the gate electrode from the active layer, a first electrode connected to a data line, and a second electrode spaced apart from the first electrode, and a micro light emitting diode on the base substrate, including a first electrode, a first buffer layer, a light emitting layer, and a second electrode, which are stacked on top of each other. The first buffer layer is in a same layer as the active layer. The second electrode of the thin film transistor is connected to one of the first electrode of the micro light emitting diode or the second electrode of the micro light emitting diode.
