The display device includes an interlayer insulating layer disposed over the substrate. The display device includes a first inner contact hole passing through the interlayer insulating layer in the encapsulation area, and connecting an inner conductive layer to an inner lower conductive layer. The display device includes an outer contact hole passing through the interlayer insulating layer in the non-encapsulation area, and connecting an outer conductive layer to an outer lower conductive layer. A slope angle formed by a lateral wall of the outer contact hole with respect to an upper surface of the substrate is less than a slope angle formed by a lateral wall of the first inner contact hole with respect to the upper surface of the substrate.

Abstract: A display device incudes a display panel and an infrared sensing module. The display panel includes an active region in which a pixel that emits light based on a data signal is disposed. The infrared sensing module transmits a first infrared light that passes through the active region and receives a second infrared light that passes through the active region to recognize an object. The wavelength of the first infrared light may have a wavelength greater than a predetermined value so that a luminance of light emitted by the pixel is not affected by operation of the infrared sensing module.
