Abstract
A display device comprises a repair circuit, and a repair circuit connection pattern extending across a pixel and the repair circuit. Each of a first and second subpixels comprises a light emitting element, a first transistor connected thereto, and a second transistor connected to a gate electrode of the first transistor. The repair circuit comprises first and second repair transistors connected to a gate electrode of the first repair transistor. A first source/drain electrode of the first transistor of each of the first and second subpixels is connected to the power line, a second source/drain electrode of the first transistor of each of the first and second subpixels overlaps the repair circuit connection pattern. A first source/drain electrode of the first repair transistor is connected to the power line, and a second source/drain electrode of the first repair transistor overlaps the first repair circuit connection pattern.
