DISPLAY DEVICE

A display device is disclosed. The display device comprises a substrate comprising a main region and a sub-region, the main region comprising a display area and a non-display area, the display area in which a plurality of sub-pixel areas configured to emit light for displaying an image are arranged, the non-display area disposed around the display area, and the sub-region protruding from one side of the main region and comprising a bending area which is deformed to be bent, a thin film transistor layer disposed on the substrate, a scan driver configured to output a scan signal to scan lines of the thin film transistor layer, a light emitting element layer disposed on the thin film transistor layer, a sensor electrode layer comprising a first sensor insulating layer and a second sensor insulating layer, control signal lines electrically connected to the scan driver and disposed in the non-display area and a first sub-region of the sub-region, control connection lines disposed in the bending area and electrically connected to the control signal lines through first control line contact holes, respectively, and a first hole protection layer disposed between the second sensor insulating layer and the control connection lines and corresponding to the first control line contact holes.
