Abstract

A diode display includes a substrate having a first island and a second island spaced apart from each other, a first pixel disposed on the first island, and a second pixel disposed on the second island. The first pixel includes a first base layer, a first transistor on the first base layer, a first light emitting element electrically connected to the first transistor, and a first encapsulation layer covering the first light emitting element. The second pixel includes a second base layer, a second transistor on the second base layer, a second light emitting element connected to the second transistor, and a second encapsulation layer covering the second light emitting element.
