Abstract: Provided is a display device. The display device includes: one or more pixels placed in an active area and a pixel circuit associated with the pixels; and a power supply line placed in an inactive area outside the active area and connected to the pixel circuit. At least one side of the power supply line may be covered with an overcoating layer. The overcoating layer includes a first portion adjacent to the side of the power supply line and a second portion which is farther from the power supply line than the first portion. The first portion has a smaller thickness than the second portion. The first portion may be about half the thickness of the second portion.

Abstract: Provided is a display apparatus. The display apparatus includes a substrate including an active area and an inactive area. The display apparatus further includes a transistor and a light emitting diode in the active area. The display apparatus further includes a circuit unit, a dam, and a reference power voltage line in the inactive area. The reference power voltage line includes a first conductive layer, a second conductive layer, and a third conductive layer in the inactive area, wherein at least one of the first conductive layer, the second conductive layer, or the third conducive layer horizontally overlaps with a remaining two conductive layers included in the reference power voltage line in a vertical direction.
