Abstract: A display device includes: a lower panel through which incident light passes and including a substrate on which a thin film transistor is disposed; a color conversion display panel from which converted light is emitted to display an image and overlapping the lower panel; and a polarization film between the lower panel and the color conversion display panel. The color conversion display panel includes a substrate on which are disposed: a first color conversion layer including first semiconductor nanocrystals which convert the incident light to the converted light; a second color conversion layer including second semiconductor nanocrystals which convert the incident light to the converted light; and a transmission layer through which unconverted incident light passes. The substrate of the lower panel or the color conversion display panel includes a flexible substrate including a polymer.
