Abstract: A device comprises a substrate, a plurality of emission portions disposed on the substrate and emitting light, a plurality of light sensing portions disposed on the substrate and sensing an incident light, a bank layer partitioning the plurality of emission portions and the plurality of light sensing portions, and a touch sensing layer disposed on the bank layer. The touch sensing layer comprises a first touch insulating pattern disposed on the bank layer and partitioning a light opening overlapping the plurality of light sensing portions and a touch electrode disposed on the first touch insulating pattern. A cross-sectional shape of the first touch insulating pattern has a reverse tapered shape having a width that decreases towards a top surface of the substrate.
