Abstract: A display device includes a support plate including first to third regions, and a display panel divided into first to third display regions overlapping the first to third regions, and including light emitting elements (LEs) and pixel circuits (PCs). The second display region includes a first partial region in which first and second PCs, and a first LE are disposed, and a second partial region in which a second LE is disposed. The third display region includes a third partial region in which third and fourth PCs, and a third LE are disposed to overlap a first support portion of the third region, and a fourth partial region in which a fourth LE is disposed to overlap each opening in the third region. A first separation distance between the second PC and the second LE is less than a second separation distance between the fourth PC and the fourth LE.

Abstract: A display device includes: a pixel including a light emitting element; a sensor including a sensing element and a sensor driving circuit; and a sensor driver to output a sensor scan signal to the sensor driving circuit. The sensor driver includes: a switching circuit connected between a first input terminal for receiving a first clock signal of a first operating frequency and a first clock node, and to output a first filtering clock signal of a second operating frequency to the first clock node in response to a first enable signal; and a driving circuit to output the sensor scan signal in response to the first filtering clock signal of the first clock node.

Abstract: A display device includes a display panel, first and second insulating layers, and a high refractive insulating layer. The display panel includes emission areas and a non-emission area. The first insulating layer is disposed on the display panel, and first openings are defined in the first insulating layer. Second openings, corresponding to the first openings, are defined in the second insulating layer having a refractive index greater than that of the first insulation layer. The high refractive insulating layer has a refractive index greater than that of the second insulating layer. The high refractive insulating layer is disposed on the first and second insulating layers. The first insulating layer includes a first inclined surface defining the first openings, and the second insulating layer includes a second inclined surface defining the second openings. The first inclined surface and the second inclined surface are spaced apart from each other.
