Abstract: A display device includes an emissive layer between a plurality of first electrodes and a second electrode, an encapsulation layer on the second electrode, an a touch layer on the encapsulation layer. A plurality of refractive patterns are on the touch layer and overlap the emissive layer, and a refractive film covers refractive patterns. Each of the refractive patterns and the refractive film comprise an organic material, and the refractive index of the refractive film is less than the refractive index of each of the refractive patterns.

Abstract: A display device includes a display member and a touch member disposed on the display member. The touch member includes a first touch insulating disposed on the display member, a first touch conductive layer disposed on the first touch insulating layer and including a touch bridge electrode, a second touch insulating layer disposed on the first touch conductive layer, including an organic material, and including a first contact hole penetrating the second touch insulating layer in a thickness direction, a second touch conductive layer disposed on the second touch insulating layer and including a first lower sensing line overlapping the second touch bridge electrode, and a third touch conductive layer disposed on the second touch conductive layer and including a first upper sensing line overlapping the first lower sensing line. A width of the first upper sensing line is greater than a width of the first lower sensing line.
