Abstract
A display device includes a substrate having a light emission area, a light emitting element layer including a light emitting element on the light emission area, and an sensing layer on the light emitting element layer and including a sensing electrode having a first opening overlapping the light emission area, a first refraction layer directly on the sensing electrode and having a second opening overlapping the light emission area, and a second refraction layer on the light emitting element layer and the first refraction layer, a first optical refractive index of the first refraction layer being less than a second optical refraction index of the second refraction layer.
