Abstract: A display device includes a base substrate having a main area, a sub-area, and a bending area. The main area includes pixels that each include a thin film transistor having a semiconductor layer, a gate electrode, a source electrode and a drain electrode. The display device includes a first insulating layer, a first conductive layer and a second insulating layer. The bending area includes a bending organic layer in a bending open portion. A second conductive layer is disposed on the second insulating layer and includes a source connection electrode. An encapsulation layer covers a light emitting element disposed on the second conductive layer for each of the pixels. A touch layer and a color filter layer are disposed on the encapsulation layer. The color filter layer includes a plurality of first color patterns overlapping the source connection electrode in the bending area that are separated from each other.
