Abstract
A display device includes a substrate including a display region and non-display region, and at least one pixel disposed in the display region. The at least one pixel includes an emission region that emits a light, a non-emission region that does not emit the light, a light emitting element disposed in the emission region, and a pixel circuit that drives the light emitting element. The display device further includes a passivation layer disposed between the pixel circuit and the light emitting element. The passivation layer covers the pixel circuit and includes a concave pattern disposed in the non-emission region. The display device further includes a power supply line disposed on the passivation layer in the non-emission region and connected to the light emitting element. The power supply line includes an uneven pattern corresponding to the concave pattern.
