AI Technical Summary
Technical Problem
In existing technologies, when repairing faulty pixels in display devices, the laser beam can easily damage the upper insulating layer and light-emitting elements, and the ultraviolet laser beam can damage the lower polarizer.
Method used
The repair pattern is overlapped with the active layer in an isolated manner, and the faulty pixel is repaired by cutting the active layer with an infrared laser beam, thus avoiding the laser beam directly acting on the conductive layer and the light-emitting element.
Benefits of technology
It effectively repairs faulty pixels, prevents damage to the insulating layer and light-emitting elements, protects the lower polarizer from damage, and improves repair efficiency and reliability.

Abstract
A display device is proposed, comprising: a substrate on which circuit elements constituting pixels are disposed; a repair pattern disposed on the substrate; a buffer layer covering the repair pattern; an active layer disposed on the buffer layer; a conductive layer on the active layer and on which electrodes of circuit elements are disposed; an outer coating layer covering the conductive layer; and a light-emitting element disposed on the outer coating layer, wherein the repair pattern is arranged such that a region thereof overlaps with the active layer.
