Abstract
A touch display device for preventing damage to test patterns is configured such that a test cover layer, which is formed of the same material as at least one of a plurality of insulating films disposed between a light-emitting element and a touch electrode, is disposed on a test pattern formed on a peripheral portion of a substrate, thereby preventing damage to the test pattern during the process of manufacturing a touch sensor.
