Abstract: A color conversion panel includes an active area corresponding to a display area and including an active pixel portion at which light is emitted, a dummy area adjacent to the active area and including a first dummy pixel portion and a second dummy pixel portion, and a color conversion layer including a bank layer in both the active area and the dummy area. The bank layer defines each of an active opening corresponding to the active pixel portion and defining an active opening planar area, a first dummy opening corresponding to the first dummy pixel portion and defining a first planar area, and a second dummy opening corresponding to the second dummy pixel portion and defining a second planar area. The first planar area of the first dummy opening is different from the second planar area of the second dummy opening.
