Abstract: A display device may include a display panel including a substrate that includes a display area and a pad area adjacent to the display area, and a first pad and a second pad on the pad area of the substrate, and a chip-on-film package over the pad area of the substrate with the first pad and the second pad in between, the chip-on-film package including an insulation layer, a first wiring on an upper surface of the insulation layer and electrically connected to the first pad, and a second wiring on a lower surface of the insulation layer and electrically connected to the second pad. A first signal having alternating voltage levels may be applied to the first wiring, and a second signal having a constant voltage level may be applied to the second wiring.

Abstract: A display device is provided. The display device includes: a display substrate on which a plurality of light-emitting areas are defined; and a color conversion substrate on which a plurality of light-transmitting areas respectively associated with the plurality of light-emitting areas and light-blocking areas between the plurality of light-transmitting areas are defined, the color conversion substrate comprising color patterns in the light-blocking areas, and light-blocking members on the color patterns, wherein at least one of the light-emitting areas has an area smaller than the area of the light-transmitting area that overlaps it in a thickness direction, and the color patterns include a blue colorant.
