Abstract: A display device includes a first pixel region (FPR), a second pixel region (SPR), a color conversion pattern (CCP), a first overcoat layer (FOL), a barrier layer (BL), a second overcoat layer (SOL), a liquid crystal layer (LCL), and a switching element (SE). The FPR is configured to display a first color (FC). The SPR is adjacent the FPR, and is configured to display a second color (SC) of a shorter peak wavelength than the FC. The CCP is disposed in the FPR, and is configured to: convert a color of incident light into the FC; and output converted light of the FC. The FOL is disposed on the CCP. The BL is of an inorganic material, and is disposed on the FOL. The SOL is of an organic material, and is disposed on the BL. The LCL is disposed on the SOL. The SE is disposed on the LCL.

Abstract: A display device and a method of manufacturing a display device are provided. An embodiment of a display device includes a substrate; a first conductive layer disposed on the substrate; a first insulating layer disposed on the first conductive layer; a second conductive layer connected to the first conductive layer through a first contact hole in the first insulating layer; a second insulating layer filling an inside of the first contact hole; and a third insulating layer disposed on the second conductive layer and the second insulating layer. The first insulating layer includes a first region that overlaps the second conductive layer and a second region that does not overlap the second conductive layer, and a top surface of the first region of the first insulating layer is positioned higher than a top surface of the second region of the first insulating layer.
