Abstract: A method of manufacturing a display device includes preparing a substrate, wherein the substrate includes a pixel area and a transmission area, forming insulating layers in the pixel area and in the transmission area, forming a pixel electrode on the insulating layers in the pixel area and forming a pixel-defining layer on the pixel electrode, wherein the pixel-defining layer exposes at least part of the pixel electrode, forming a metal layer on the pixel-defining layer in the pixel area, the at least part of the pixel electrode exposed by the pixel-defining layer in the pixel area, and the insulating layers in the transmission area, removing the metal layer on the insulating layers in the transmission area, and removing the insulating layers in the transmission area.

Abstract: A display apparatus includes a base substrate, an active pattern on the base substrate including a source region, a drain region, and a channel region that is doped between the source region and the drain region, the channel region including polycrystalline silicon, and a gate electrode overlapping the channel region of the active pattern. The channel region may include a lower portion, an upper portion, and an intermediate portion between the upper portion and the lower portion, and a dopant density of the lower portion may be 80% or more of a dopant density of the upper portion.
