Abstract: A display device includes: a display substrate; an opposing substrate opposing the display substrate; and a light amount control layer disposed between the display substrate and the opposing substrate. The display substrate includes: a first substrate; a thin film transistor o disposed n the first substrate; and a pixel electrode connected to the thin film transistor. The opposing substrate includes: a second substrate; a color conversion layer disposed on the second substrate; and a first polarizer disposed on the color conversion layer. The first polarizer includes: a base substrate; and a linear polarizer disposed on one surface of the base substrate. The first polarizer opposes the pixel electrode. The one surface of the base substrate on which the linear polarizer is disposed has a flatness of about 60 nm or less.
