Disclosed is a display device. The disclosed display device includes a structure in which at least one blue light emitting unit and at least one green light emitting unit are stacked, and includes an OLED substrate emitting blue light and green light mixed light, and for controlling the color of the light generated from the OLED substrate. It may include a color control unit. The OLED substrate may have a tandem structure, and may include, for example, a first blue light emitting unit, a green light emitting unit, and a second blue light emitting unit. The color control unit includes a first color control element including a first quantum dot for green conversion, a second color control element including a second quantum dot for red conversion, a third color control element for blue expression, and the first color a first color filter provided on the control element and a second color filter provided on the second color control element, wherein at least one of the green light emitting units of the OLED substrate includes an organometallic compound represented by the following Chemical Formula 1 can do: <Formula 1> M(L 1 ) n1 (L 2 ) n2 For the description of M, L 1 , n1, L 2 and n2 in Formula 1, refer to the bar described in the present specification, respectively. |
