DISPLAY DEVICE

A display device includes: a display panel including: an active area; a peripheral area adjacent to the active area; a circuit layer including a plurality of insulation layers including: at least one lower insulation layer; and at least one upper insulation layer including an inorganic material; and an element layer including a plurality of light emitting elements in the active area, and a plurality of light sensing elements in the active area. The peripheral area includes an open area in which the at least one upper insulation layer is not disposed, and the circuit layer includes: a plurality of readout lines electrically connected with the plurality of light sensing elements, and extending from the active area to the peripheral area; and an inorganic insulation pattern overlapping with the open area and at least a portion of the plurality of readout lines.
